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.

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

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

Attach drywall to metal studs up to 0.036" thick.

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

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.

These blue and silver ultra-corrosion-resistant coated steel screws stand up to wet environments.

Also known as Tapcons, use these screws in applications requiring high strength.

These 410 stainless steel screws are more corrosion resistant than ultra-corrosion-resistant coated steel screws.

Use these stud-style anchors with nuts.

Fins prevent these anchors from spinning during installation.

A spring-loaded toggle holds against the back of the material.

Use these stud-style anchors with nuts.

High-strength toggle anchors provide an extremely strong hold and stay in position when a bolt is removed.

Keep fixtures solidly in place—these anchors have two locking wedges that won't shake loose.

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

A zinc plating provides corrosion resistance in wet environments.

An open-end cap nut provides a finished appearance.

Bolts are beveled under the head for a flush finish in countersunk holes.

Use in applications requiring high strength.

A zinc plating provides corrosion resistance in wet environments.

Also known as caulk-in anchors, these stay secure when there's not much material to hold.

The fastest way to install shallow-hole female-threaded anchors. Just push the tip of the tool into the anchor and turn the tool with a power drill.

Often referred to as four-way expansion anchors, these expand in four directions to resist loosening from vibration.

Install like a stud anchor—just thread the anchor, a nut, and a washer onto the end of a threaded rod, drive into a hole, and turn the nut to expand the base. Also known as rod anchors, they're often used with threaded rod to hang pipe and wiring.

Drive these tools with a hammer until the thicker portion of the tool makes contact with the anchor, causing it to expand.

These 316 stainless steel anchors have excellent resistance to chemicals and salt water.

Used with adhesive in bricks and hollow blocks, such as cinder blocks, these mesh tubes create a stronger hold for rods and studs than other anchors.

A pivoting toggle bar creates a strong hold.

These steel anchors are available with corrosion-resistant finishes.

These steel anchors are available with corrosion-resistant finishes.

A wing-like toggle holds against the back of the material and spreads the force over a large area to hold 30 lbs. or more.

18-8 stainless steel has good corrosion resistance.

Use these bits with handheld power drills, drill presses, and hammer drills.

These bits have a round or hex shank that fits into the three-jaw chuck on a hammer drill.

These hollow bits cut with their outside edge for drilling holes larger than 1 1/2" in diameter.

These bits allow you to easily switch to another size by changing only the bit body. They are hollow and cut with their outside edge for drilling holes larger than 1 1/2" in diameter.

Drill holes up to 1 1/2" in diameter.

Use these diamond-coated hollow bits for wet drilling of masonry, concrete, and rebar with a drilling rig.

The SDS-Max shank has three deep slots and two shallow slots for use with SDS-Max-drive rotary hammers.

The SDS-Plus shank has two deep slots and two shallow slots for use with SDS-Plus-drive rotary hammers.

A more controlled chip removal reduces heat buildup. Use these bits on brittle materials such as block and brick.
