Stainless Steel Button Head Hex-Drive Screw Assortments
 |
Keep a variety of corrosion-resistant button head screws on hand for a range of fastening jobs. Made of stainless steel, these screws won't rust, but they're not as strong as alloy steel. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver.
Length is measured from under the head.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel can.

Steel Hex-Drive Flat Head Screw Assortments
|
With a range of sizes on hand, you can use these assortments to fasten a variety of machinery and equipment. They're made of alloy steel, so they have nearly twice the tensile strength of other screws. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver without slipping and stripping the drive.
Length is measured from the top of the head.
Black-Oxide Alloy 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.

Steel Hex Head Screw Kits
 |  |  |
Fully Threaded | Partially Threaded |
Everything you need for a complete, strong joint—the screws in these kits come with compatible nuts and washers. The screws have a head with six flat sides to keep wrenches and sockets from slipping and rounding off the drive. Washers distribute pressure on both sides of your material, so the nut tightens onto the screw without damaging surfaces.
Screw length is measured from under the head.
Medium-Strength Fastener—Your go-to screws for fastening most machinery and equipment. They have tensile strengths from 90,000 to 120,000 psi.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Stainless Steel Flanged Hex Head Screw and Nut Assortments
 |
Different sizes of corrosion-resistant flanged fasteners for a variety of jobs. The screws and nuts in these assortments both have a flange that spreads pressure over a wide area to protect thin and soft materials. The screws have a head with six flat sides to keep wrenches and sockets from slipping and rounding off the drive.
Head height includes the flange. Length is measured from under the flange.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel screws can.

Steel Button Head Hex-Drive Screw Assortments
 |
Keep multiple sizes of our strongest rounded head screws on hand for a variety of fastening jobs. These screws are made of alloy steel, so they have nearly twice the tensile strength of other screws. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver.
Length is measured from under the head.
Black-Oxide Alloy 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.
