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.

Steel Flanged Spade-Head Thumb Screws
 |
A built-in flange distributes pressure in thin and soft materials—no washer needed. It also provides extra surface area under the 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.
Steel—An economical choice that's strong, but rusts in moisture. They're best for dry environments.
Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.

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.

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.
