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 Hex Head Screw Kits
 |
 |
Fully Threaded |
 |
Partially Threaded |
Everything you need for a complete, corrosion-resistant 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.
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.

Stainless Steel Hex Head Screw, Nut, and Washer Assortments
 |
Stock up on different sizes of corrosion-resistant hex head screws, nuts, and washers. The screws have a head with six flat sides to keep wrenches and sockets from slipping and rounding off the drive.
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 screws can.
Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel screws, these won't degrade when exposed to harsh weather, salt water, and most chemicals.

Steel Hex Head Screw, Nut, and Washer Assortments
 |
Keep a range of hex head screw, nut, and washer sizes on hand for a variety of jobs. The screws in these assortments have heads with six flat sides to keep wrenches and sockets slipping and rounding off the drive.
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.
High-Strength Fastener—Commonly used to fasten components in valves, pumps, motors, and other high-stress applications. These screws have a tensile strength of 125,000 to 160,000 psi.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
Zinc-Yellow-Chromate-Plated Steel—With slightly better corrosion resistance than zinc-plated steel screws, these stand up to more frequent exposure to moisture.

Steel Hex Head Screw Kits for Plastic Pipe Flanges
 |  |
Shown Installed |
All the hardware you need to join plastic pipe flanges. These kits come with screws, nuts, and washers in the right size and number to match your flange's bolt holes. The screws have a head with six flat sides to keep wrenches and sockets from slipping and rounding off the drive.
Screw length is measured from under the head. For a tight seal, you’ll also need a gasket between the flanges.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
