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

These steel screws cut threads in drilled holes as they’re turned, so they require less driving torque and cause less stress on your material than thread forming screws.

A Torx drive has more points of contact than a Phillips drive, allowing you to apply extra force with less slippage or damage to the recess.

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

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

These metric screws have a triangular shank that 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.
