Steel Extended-Tip Set Screws

Like a dowel pin, the tip slides into mating holes to locate and hold components on shafts, tubing, and other surfaces. Made of alloy steel, these screws are strong enough to hold components without wearing down. Also known as half dog-point set screws.

Stainless Steel Extended-Tip Set Screws

Our most corrosion-resistant extended-tip set screws. Made of stainless steel, they won't rust, but they're not as strong as alloy steel. Like a dowel pin, the tip slides into mating holes to locate and hold components on shafts, tubing, and other surfaces. Also known as half dog-point set screws.

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.
