Stainless Steel Flared-Collar Knurled-Head Thumb Screws
 |  |
A flared collar leaves more space for your fingers to grasp these corrosion-resistant thumb screws. It also serves as a decorative finish. The knurled texture on the head creates extra grip as you twist.
Length is measured from under the collar.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Stainless Steel Raised-Profile Knurled-Head Thumb Screws
 |  |
The raised head gives your fingers extra space to grab these corrosion-resistant thumb screws, even with oily fingers. The knurled texture creates extra grip as you twist. Install these thumb screws on panels and covers for routinely serviced equipment, such as HVAC access doors and machine safety shields.
Length is measured from under the collar.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Steel Raised-Profile Knurled-Head Thumb Screws
 |  |
The raised head gives your fingers extra space to grab these thumb screws, even with oily fingers. The knurled texture creates extra grip as you twist. Install these thumb screws on panels and covers for routinely serviced equipment, such as HVAC access doors and machine safety shields.
Length is measured from under the collar.
Black-Oxide Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

Stainless Steel Narrow-Profile Knurled-Head Thumb Screws
 |
The slim head on these corrosion-resistant thumb screws won't snag plugs and cords in electrical panels and other tight spaces. The narrow width can make them harder to turn than screws with wider heads. However, the knurled texture gives your fingers extra grip.
Length is measured from under the head.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Hex-Drive Plastic-Head Thumb Screws
 |
Twist these thumb screws with a hex key when you need more torque than fingers can provide. You can also use a hex key to unfasten them in cramped spaces such as small control boxes. When fastening these thumb screws by hand, the knurled texture of the head creates extra grip as you twist. These thumb screws combine the strength of stainless steel with a lightweight plastic head that won't rust.
Length is measured from under the head.

Stainless Steel High-Profile Knurled-Head Thumb Screws
 |
These corrosion-resistant thumb screws have a head that's twice as tall as low-profile ones for added leverage. Grasp and turn these screws, even with oily fingers. The knurled texture on the head creates extra grip as you twist. Install these thumb screws in regularly inspected and maintained equipment, such as safety enclosures on CNC machines.
Length is measured from under the head.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Stainless Steel Extended-Tip Thumb Screws
 |
Corrosion resistant with an extended tip that acts like a dowel to fit into mating holes, align and hold parts together, and prevent cross-threading. Fasten these screws in workpieces that you regularly reposition or align. The knurled texture on the head creates extra grip as you twist. Also known as dog-point and pilot-point thumb screws.
Length is measured from under the head.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Steel Four-Arm Extended-Tip Thumb Screws
 |
Four arms and an extended tip help you guide these screws into holes with greater control. The arms of the head have more surface area to grip than knurled-head thumb screws. The extended tip acts like a dowel—it fits into mating holes, aligns and holds parts together, and prevents cross-threading. Use these screws for workpieces that you regularly reposition or align. Also known as dog-point and pilot-point thumb screws.
Length is measured from under the collar.
Black-Oxide Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

Plastic Raised-Profile Knurled-Head Thumb Screws
 |  |
The raised head gives your fingers extra space to grab and twist these thumb screws. The knurled texture creates added grip as you twist. Install these thumb screws on panels and covers for routinely serviced equipment, such as HVAC access doors and machine safety shields. A lightweight, economical alternative to metal thumb screws, these plastic ones are nonconductive and naturally rust resistant.
Length measured from under the collar.
Nylon—These screws are slippery and abrasion resistant, so they thread in smoothly and stand up to daily wear and tear.
Glass-Filled Nylon—Reinforced with glass fibers and stronger than standard nylon screws.

Slotted Stainless Steel Knurled-Head Thumb Screws
 |
Fasten these corrosion-resistant thumb screws by driver and by hand. In cramped spaces where fingers can't fit, such as small control boxes, turn these screws with a slotted driver. When twisting by hand, the knurled texture of the screw head creates extra grip.
Length is measured from under the head.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Stainless Steel Flanged Spade-Head Thumb Screws
 |
These corrosion-resistant thumb screws have a built-in flange that distributes pressure in thin and soft materials—no washer needed. It also provides extra surface area under the screw head to hold down material. The head of these thumb screws is slim and flat like a coin for extra leverage when twisting.
Length is measured from under the flange.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Slotted Plastic High-Profile Knurled-Head Thumb Screws
 |
Twist these nonconductive, rust-resistant, lightweight thumb screws by driver and by hand. The head is nearly twice as tall as low-profile heads for a better grasp. In cramped spaces where fingers can't fit, such as small control boxes, turn these screws with a slotted driver. When twisting by hand, the knurled texture of the screw head creates extra grip.
Length is measured from under the head.
Nylon—These screws are slippery and abrasion resistant, so they thread in smoothly and stand up to daily wear and tear.

Self-Aligning Four-Arm Swivel-Tip Thumb Screws
 |  |
The large tip on these thumb screws secures a bigger surface area than our other swivel-tip screws. It pivots to sit flat against uneven and angled workpiece surfaces without causing damage. Remove the tip to thread these screws through a hole, then reattach the tip on the other side. The four arms of the head create natural grooves for your hand to grip when fastening.
Length is measured from under the collar.
Black-Oxide Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
Extra Large—To maximize surface contact, these are twice the size of the tip included with these thumb screws.
Acetal Tips—Nonmarring, so they're safe to use on delicate surfaces.

Slotted Stainless Steel Narrow-Profile Knurled-Head Thumb Screws
 |
Fasten these slim, corrosion-resistant screws by driver and by hand in even the tightest of spaces. Turn these screws with a slotted driver in cramped spaces where fingers can't fit. When twisting by hand, the knurled texture of the screw head creates extra grip.
Length is measured from under the head.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Steel Extended-Tip Thumb Screws
 |
The extended tip acts like a dowel to fit into mating holes, align and hold parts together, and prevent cross-threading. Fasten these screws in workpieces that you regularly reposition or align. The knurled texture of the head creates extra grip as you twist. Also known as dog-point and pilot-point thumb screws.
Length is measured from under the head.
Black-Oxide Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

Plastic Thumb Screws
 |
A lightweight, economical alternative to metal thumb screws, these plastic ones are nonconductive and naturally rust-resistant. The knurled texture on the head creates extra grip as you twist.
Length is measured from under the head.
Nylon—These screws are slippery and abrasion resistant, so they thread in smoothly and stand up to daily wear and tear.

Sanitary Thumb Screws
 |
Harsh cleaners and sanitizers won't corrode these stainless steel thumb screws. Fasten in areas that experience frequent washdowns, such as food and pharmaceutical plants. These screws have smooth sides and rounded edges to reduce the risk of bacteria growth. The head is slim and flat like a coin for extra leverage when twisting. Fasten with a sanitary sealing washer (sold separately) to keep contaminants out, lock fluids in, and eliminate space where bacteria can get caught.
Length is measured from under the head.
EPDM Sealing Washers—These washers are highly resistant to tearing, scuffs, and scrapes. They are more economical than Fluoroprene Fluoroelastomer, however, they aren't as heat resistant.
Fluoroprene Fluoroelastomer Sealing Washers—These sanitary sealing washers withstand higher temperatures than EPDM, so you can sterilize them with steam. They also resist more chemicals, such as oil, solvents, and acids.

Secure components at an angle or against uneven surfaces with these thumb screws. The tip pivots to conform to surfaces and is narrow enough to fit through threaded holes. The knurled texture of the head creates extra grip as you twist.
Length is measured from under the head.
Black-Oxide Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

Stainless Steel Hex-Head Thumb Screws
 |
When you need more torque than fingers alone can provide, crank these stainless steel thumb screws with a wrench. For finger tightening, the thick, hex-shaped head transmits added torque for a stronger hold than other head shapes. These thumb screws aren't recommended for structural, load-bearing applications.
Length is measured from under the head.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
