About Tapping Screws

Screws for Joining Sheet Metal to Wood

Able to penetrate overlapping sheets, these screws have a secure hold in wood.

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.

Steel Hex Head Thread-Cutting Screws for Metal

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

Stainless Steel Hex Head
Thread-Cutting Screws for Metal

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

Steel Rounded Head
Thread-Cutting Screws for Metal

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

Stainless Steel Rounded Head
Thread-Cutting Screws for Metal

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

Quick-Install Thread-Cutting Screws for Soft Metal

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

Hinge Screws

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

Electrical Grounding Screws

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

Screws for Wood

Steel Phillips Drilling Screws
for Joining Wood to Metal

These screws speed installation by drilling, tapping, and fastening wood and metal in a single operation.

Stainless Steel Phillips Drilling
Screws for Joining Wood to Metal

18-8 stainless steel screws have good chemical resistance.

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.

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.

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.

Distortion-Free Screws for Plastic-Wood Composites

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

Sealing Screws for Softwood
and Plastic-Wood Composites

The neoprene-backed washer seals out contaminants.

Tapping Screws for Plastic

Thread-Cutting Screws for Plastic

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

Stainless Steel Hex Head Screws
for Joining Plastic to Wood

18-8 stainless steel screws have good chemical resistance.

Steel Hex Head Screws for Joining Plastic to Wood

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

Rounded Head Screws for Joining Plastic to Wood

Cutting wings under the head allow plastic to expand and contract without cracking. A washer made from aluminum and rubber bonded to steel adds a watertight seal.
