Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws.

Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws.

More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water. They may be mildly magnetic.

Brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

These screws are drilled through the shaft to vent fluids and gases trapped under the screw.

Made from 316 stainless steel, these set screws have excellent chemical resistance and can be used in saltwater environments.

Brass set screws are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

Made from black-oxide alloy steel, these set screws resist corrosion in dry environments. They dig into hard surfaces for a secure hold and have serrations on the cup edge that grip the material surface to resist loosening.

These alloy steel set screws have a thin edge that digs into hard surfaces for a secure hold. A nylon locking element grips threads to resist loosening.

These 18-8 stainless steel set screws are chemical resistant. They have a nylon locking patch that grips threads to resist loosening.

Made from 18-8 stainless steel, these set screws are chemical resistant. The tip makes good contact on flat surfaces and allows you to make frequent adjustments with minimal surface damage.

A nylon locking patch grips threads to resist loosening.

These metric set screws have a brass tip, which is harder than nylon and silver, for a secure hold on hard surfaces. The body has a black-oxide finish to resist corrosion in dry environments.

Available in metric sizes, these screws have a tip that is harder than nylon and silver to provide a secure hold on hard surfaces. The body is 18-8 stainless steel for good chemical resistance.

Available in metric sizes, these alloy steel set screws have an extra-soft nylon tip that minimizes the damage that can occur from metal-on-metal contact. Use them on soft surfaces such as aluminum.

These alloy steel set screws have an extra-soft nylon tip, which minimizes the damage that can occur from metal-on-metal contact. Use them set screws on soft surfaces such as aluminum.

Made of alloy steel, these set screws are often used in U-shaped and V-shaped grooves and on other sloped or angled surfaces. The oval tip allows for frequent adjustments with minimal surface damage.
