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

These steel screws are zinc plated to resist corrosion in wet environments.

Made from 18-8 stainless steel, these screws are chemical resistant.

A rubber O-ring under the head creates a seal that withstands liquid and gas pressure.

Made from 410 stainless steel, these screws are strong, wear resistant, and mildly chemical resistant.

These steel screws are zinc plated to resist corrosion in wet environments.

These steel screws are zinc plated to resist corrosion in wet environments.

A wide cutting slot provides excellent chip clearing and low driving torque in soft metal.

The green color identifies these as grounding screws. They have a flange that provides a wide flat surface for making solid electrical connections.

The triangular shank presses tightly as it forms threads, so screws resist loosening in soft metals such as brass, aluminum, and copper.

Also known as Swageform screws, threads at the tip are designed to grab material for a fast start with low torque in a wide range of materials.

Threads change direction to cut into composites and push material back into the hole to prevent distorting the surface around the hole.

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

18-8 stainless steel screws have good chemical resistance.

18-8 stainless steel screws have good chemical resistance.

Press threads into plastic to create a strong hold. Use a wrench, hex socket bit, or nutdriver to securely grip the hex head and tighten these screws.

18-8 stainless steel screws have good chemical resistance.

Stronger and more wear resistant than 18-8 stainless steel screws, these are mildly chemical resistant.

Screws are beveled under the head for use in countersunk holes.
