Steel Oval-Tip Set Screws

Adjust as often as you need without scratching or gouging shafts and other mating parts. With a rounded tip, these set screws won't dig into surfaces like cone- and cup-tip screws do. Since the round tip makes contact at an angle, they're good for surfaces with U- or V-shaped grooves. Made of alloy steel, these screws are 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.

Stainless Steel Oval-Tip Set Screws

The most corrosion-resistant oval-tip set screws we offer. Made of stainless steel, they won't rust, but they're not as strong as alloy steel. With a rounded tip, these screws won't dig into surfaces like cone- and cup-tip screws do. This makes them ideal for when you need to adjust screws frequently while avoiding scratches on mating parts. Since the round tip makes contact at an angle, they're good for surfaces with U- or V-shaped grooves.

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.

Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these screws won't degrade when exposed to harsh weather, salt water, and most chemicals.
