About Tapping Screws

Metric Steel Flat Head Drilling Screws for Metal

With a drilling tip, these metric screws cut their own pilot hole and threads as you fasten them into material.

Steel Phillips Flat Head
Thread-Cutting Screws for Metal

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.

Stainless Steel Phillips Flat Head
Thread-Cutting Screws for Metal

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

Torx Flat Head Thread-Cutting Screws for Metal

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.

Metric Stainless Steel Phillips Oval
Head Thread-Cutting Screws for Metal

For a finished appearance that reduces the chance of snags on other material, these screws fit snugly in countersunk holes and have a domed head.

Hinge Screws

Commonly used with door hinge hardware, these screws cut threads in material such as aluminum and brass.

Screws for Wood

Screws for Hardwood

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.

18-8 Stainless Steel Square-Drive Screws
for Softwood and Plastic-Wood Composites

18-8 stainless steel screws have good chemical resistance.

Super-Corrosion-Resistant 316
Stainless Steel Square-Drive Screws for
Softwood and Plastic-Wood Composites

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

Steel Thread-Cutting Small-Head Screws
for Softwood and Plastic-Wood Composites

Because these steel screws cut threads into drilled holes as they’re turned, they require less driving torque and cause less stress on material than thread-forming screws. Also known as trim-head deck screws, they have a small flat head and slender shank to reduce the risk of splitting boards.

18-8 Stainless Steel Thread-Cutting Small-Head
Screws for Softwood and Plastic-Wood Composites

18-8 stainless steel screws have good chemical resistance.

Super-Corrosion-Resistant 316 Stainless
Steel Thread-Cutting Small-Head Screws
for Softwood and Plastic-Wood Composites

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

Sealing Screws for Softwood
and Plastic-Wood Composites

The neoprene-backed washer seals out contaminants.
