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.

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.

Also known as Type 17 auger point screws, these penetrate hardwood and reduce driving torque. They require a pilot hole to prevent splitting when used near an edge.

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

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