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

A Torx drive has more points of contact than Phillips, slotted, and square drives, allowing you to apply extra force with less slippage or damage to the recess.

A flange under the head distributes holding pressure and reduces the risk of crushing thin metal.

A free-rotating, permanently attached washer distributes holding pressure over a wider area than a flange and remains stationary to prevent scratching the material surface as you tighten the screw.

These steel screws have a black-oxide finish to resist corrosion in dry environments.

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

These screws have a hex head for a secure grip with a wrench.

Also known as Fastite screws, these offer more thread engagement in 0.028" to 0.063" thick sheets to prevent overtightening and damaging threads.

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

410 stainless steel is strong, wear resistant, and mildly chemical resistant.

These screws have the strength of 410 stainless steel with added corrosion resistance.

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

18-8 stainless steel screws have good chemical resistance.

By drilling their own holes and fastening in a single operation, these square-drive screws save time and effort. Made of 410 stainless steel, they're both stronger and more wear resistant than 18-8 stainless steel screws.

Also known as pancake head screws, these have a head that is about two-thirds the height of standard rounded head screws.

Made from stainless steel, these screws are more corrosion resistant than steel, and almost as strong.

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

A tamper-resistant Torx driver is required for installation and removal. Also known as pin-in-Torx, these screws allow you to apply extra force with less slippage or damage to the recess.

These steel screws have a head encapsulated by 18-8 stainless steel.

Beveled under the head for use in countersunk holes.

Serrations under the head act as a brake to prevent overtightening and damaging threads.

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.

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

Also known as Swageform screws, threads at the tip are designed to grab material for a fast start with low torque in a wide range of materials.

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.

Attach metal framing to metal studs up to 0.036" thick.

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

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.

These square-drive screws have a drill point that powers through drywall and into metal studs up to 0.105" thick. Heads are one-third smaller than those of other drywall screws.

With a square-drive head, these screws attach drywall to metal studs up to 0.036" thick. The head is one-third smaller than other drywall screws.
