About Tapping Screws

Steel Phillips Flat Head Screws for Wood

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

18-8 Stainless Steel Phillips
Flat Head Screws for Wood

18-8 stainless steel screws have good chemical resistance.

Super-Corrosion-Resistant 316 Stainless
Steel Phillips Flat Head Screws for Wood

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

Brass Phillips Flat Head Screws for Wood

Brass screws are corrosion resistant in wet environments and electrically conductive.

Steel Square-Drive Flat Head Screws for Wood

Beveled under the head for use in countersunk holes, these steel screws press threads into material for a tight, secure hold.

Brass Square-Drive Flat-Head Screws for Wood

Brass screws are corrosion resistant in wet environments and electrically conductive.

Steel Slotted Flat Head Screws for Wood

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

Brass Slotted Flat Head Screws for Wood

Brass screws are corrosion resistant in wet environments and electrically conductive.

Stainless Steel Slotted Flat Head Screws for Wood

18-8 stainless steel screws have good chemical resistance.

Torx Flat Head Screws for Wood

With more points of contact than Phillips-, slotted-, and square-drive screws, you can firmly press these Torx-drive screws into wood without stripping them or damaging the recess—their threads create a tight hold.

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.

Torx Drilling Screws for Joining Wood to 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.

Thread-Forming Screws for Joining Wood to Metal

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

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.

Steel Flat Head Screws for Plywood
and Oriented Strand Board

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

Super-Corrosion-Resistant 316
Stainless Steel Flat Head Screws for
Plywood and Oriented Strand Board

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

18-8 Stainless Steel Flat Head Screws
for Plywood and Oriented Strand Board

18-8 stainless steel screws have good chemical resistance.

Flat Head Screws for Particleboard and Fiberboard

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

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.

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 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.

Sealing Screws for Softwood
and Plastic-Wood Composites

The neoprene-backed washer seals out contaminants.

Blunt Screws for Wood

Often used for drawer slides and cabinet hardware, these screws—also known as Euro and Type B screws—create a strong hold in small, shallow holes in wood.

Screws for Joining Drywall to Wood

Hang drywall to wood framing. These screws have a sharp point that penetrates drywall and a curved neck that sinks in without tearing the paper surface.

High-Hold Screws for Joining Drywall to Wood

Alternating high and low threads minimize driving torque and allow the screw to hold more material between threads for a stronger hold and better strip-resistance than standard drywall screws for wood.

Strip-Resistant Screws for Joining Drywall to Wood

Ribs under the head act as a brake to prevent over-tightening and damaging threads.
