Steel Cup-Tip Set Screw Assortments

Keep a range of sizes on hand to fasten a variety of machinery and equipment. These screws are made of alloy steel, so they're strong enough to hold components without wearing down. The tip has thin edges that dig into surfaces for a secure hold. They often lock gears, pulleys, and other transmission components onto shafts.

Black-Oxide Alloy Steel—These screws have a dark matte finish that offers minimal corrosion resistance, so they're best for dry environments.

Zinc-Plated Alloy Steel—A common choice for areas with occasional exposure to moisture.

Stainless Steel Cup-Tip Set Screw Assortments

Keep a range of sizes on hand of our most corrosion-resistant set screws. Made of stainless steel, they won't rust, but they're not as strong as alloy steel. The tip has thin edges that dig into surfaces for a secure hold. These screws often lock gears, pulleys, and other transmission components onto shafts.

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.

Serrated-Locking Steel Cup-Tip Set Screw Assortments

Keep a variety of set screws on hand that won’t shake loose from vibrating machinery. The set screws in these assortments have knurled edges that dig deep into your material to stay put. They hold on tighter than standard cup tips, so they’re often used on gears, pulleys, and other moving equipment. Made of alloy steel, they’re strong enough to hold components without wearing down.

Black-Oxide Alloy Steel—These screws have a dark matte finish that offers minimal corrosion resistance, so they're best for dry environments.

Clamp-On Framing and Fittings

Fittings come in two pieces to clasp over rails, making assembly and disassembly quicker than our other framing. Use it to form temporary partitions, modular conveyors, and workstations. To assemble, clamp fittings onto the rail and tighten the included cap screw and nut. For permanent connections and added strength, fittings have a _5/32" hole to drill in an additional screw (not included).

Nylon-Tip Stainless Steel Set Screw Assortments

Stock up on set screws that won’t mar delicate surfaces or rust from moisture. The set screws in these assortments have a soft nylon tip for holding glass, plastic, or polished metals. The stainless steel body holds up in wet areas, but it’s not as strong as an alloy steel body.

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.
