About Hex Head Screws and Bolts

These assortments include hex head screws and hex nuts. Length is measured from under the head.

Grade 5 and Class 8.8 steel screws are suitable for fastening most machinery and equipment. Zinc-plated steel screws resist corrosion in wet environments.

Grade 8 and Class 10.9 steel screws are about 25% stronger than Grade 5 and Class 8.8 steel screws. Zinc yellow-chromate plated steel screws are more corrosion resistant than zinc-plated screws in wet environments.

18-8 stainless steel screws are chemical resistant and may be mildly magnetic.

Shoulder Screw Assortments

Shoulder screws have a cylindrical shoulder under the head that allows parts to rotate around or slide along its length. They have a standard shoulder with an undersized tolerance to fit most machinery and equipment.

Alloy steel shoulder screws are stronger than stainless steel shoulder screws. They are comparable to Grade 8 screws.

18-8 stainless steel shoulder screws are chemical resistant and may be mildly magnetic.

Stainless Steel Hex Screw and Nut Kits for Pipe Flanges

Stainless Steel

Stainless Steel with Blue PTFE-Coated Nuts

Use these kits to connect standard-size stainless steel pipe flanges for ANSI Class 150 or 300. They meet ASTM specifications for material quality, and the dimensions meet ASME specifications. Length of screws is measured from under the head.

18-8 stainless steel kits have good chemical resistance and may be mildly magnetic.

316 stainless steel kits are more corrosion resistant than 18-8 stainless steel and have excellent resistance to chemicals and salt water. They may be mildly magnetic. Some kits have blue PTFE-coated nuts. This coating is slippery, chemical-resistant, and prevents galling. It also helps nuts thread smoothly.

Attach deck and platform flooring without unsightly screw holes. These kits conceal screw holes that can snag shoes and show wear over time. They’re compatible with almost all flooring, including composite wood, pressure-treated wood, and vinyl. Because these screws are used outdoors, they have a ceramic coating to prevent rust. The brackets are UV-resistant polycarbonate, so daily sunlight won't cause them to become brittle and crack.

Bottom-mounting kits have brackets that install from beneath the flooring. They work with smooth boards that don't have grooves on the side. Brackets with spacers create a consistent 3/16" gap between floorboards, so water and melting snow run off. Use brackets without spacers to create your own spacing.

Side-mounting brackets install from above the flooring, so you don't have to crawl into cramped spaces or reach overhead. However, one bracket secures two boards, making it more difficult to swap out a single damaged board. Use them to fasten grooved boards, but you can add grooves to your boards using a router bit. Clips (sold separately) anchor the outer edge of the first and last board.
