About Tapping Screws

18-8 Stainless Steel Phillips Rounded
Head Thread-Forming Screws for Plastic

These 18-8 stainless steel screws have good chemical resistance.

Super-Corrosion-Resistant 316 Stainless
Steel Phillips Rounded Head
Thread-Forming Screws for Plastic

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

Steel Phillips Rounded Head
Thread-Forming Screws for Plastic

Stainless Steel Torx Rounded Head
Thread-Forming Screws for Plastic

18-8 stainless steel screws have good chemical resistance.

Steel Torx Rounded Head
Thread-Forming Screws for Plastic

These steel screws have a black-oxide or zinc-plated finish to resist corrosion.

Stainless Steel Flat Head
Thread-Forming Screws for Plastic

18-8 stainless steel screws have good chemical resistance.

Steel Flat Head Thread-Forming Screws for Plastic

These steel screws are beveled under the head for use in countersunk holes.

Hex Head Thread-Forming Screws for Plastic

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.

Stainless Steel Thread-Forming
Screws for Thin Plastic

18-8 stainless steel screws have good chemical resistance.

Steel Thread-Forming Screws for Thin Plastic

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

Steel Rounded Head Thread-Forming
Screws for Brittle Plastic

These steel screws have alternating high and low threads to minimize cracking and splitting in brittle material such as phenolic and glass-filled plastic.

18-8 Stainless Steel Rounded Head
Thread-Forming Screws for Brittle Plastic

18-8 stainless steel screws have good chemical resistance.

High-Strength 410 Stainless Steel Rounded
Head Thread-Forming Screws for Brittle Plastic

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

Flat Head Thread-Forming Screws for Brittle Plastic

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

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.

Pointed Screws for Plastic

A point centers the screw in a starter hole and widely spaced threads reduce the risk of cracking plastic.

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.

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.

Screws for Softwood and Plastic-Wood Composites

Phillips Screws for Softwood
and Plastic-Wood Composites

Also known as deck screws, these Phillips screws have a sharp point and narrow body to penetrate softwood and plastic-wood composite decking material.

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.

Thread-Forming Small-Head Screws for
Softwood and Plastic-Wood Composites

Thread-forming screws press threads into drilled holes for a tight, vibration-resistant assembly.

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.
