Wood Screw Driver Bits

Choose the correct 4-inch driver bit for your wood screw.

An accurate driver tip fit is required for proper screw installation, especially with brass screws. Brass is softer than steel. A tip that does not fit the screw correctly can slip, damage the slot, strip the head, or contribute to a broken screw.

All options are 4-inch round-body power bits with 1/4-inch hex shanks.

Choose the correct tip

• Phillips #1 — for smaller Phillips recesses
• Phillips #2 — for the most commonly encountered Phillips recesses
• Phillips #3 — for larger Phillips recesses
• Slotted #6–7 — for #6 and #7 slotted wood screws
• Slotted #8–10 — for #8 through #10 slotted wood screws
• Slotted #10–12 — for #10 through #12 slotted wood screws
• Slotted #12–14 — for #12 through #14 slotted wood screws

Choose the tip that seats fully and securely in the screw head before applying power.

Installing brass screws

Set the clutch low on your drill and use the proper predrill size. Apply wax to the screw threads when installing in hardwood.

If driving the screw requires more power than you could reasonably apply with a screwdriver by hand, stop. Excess force can snap a brass screw.

When in doubt, finish with a hand screwdriver. If the screw is difficult to back out, the predrilled hole is probably too small. Increase the predrill size, apply wax, and try again.
