Break stuck screws free using screwdriver bits. Strike the end of the handle with a hammer to turn the bit and tighten or loosen fasteners. Use these tools as an impact wrench without the bit adapter.

When vertical space is tight or you need an extra twist on your socket, use one of the dual-drive Phillips bit sockets in this set. They work with a standard square-drive tool and a box or open-end wrench. Tighten them with your square-drive tool and give them an additional turn with the leverage from your open-end or box wrench. Or just use a box or open-end wrench when you can’t fit your square-drive tool. Pair them with hand-drive tools only. The sockets in these sets come with a clip rail to make sure they stay put and organized when not in use.

Drive Pozidriv® fasteners with a ratchet or torque wrench for greater torque control and less wrist fatigue. The Pozidriv tip resists cam-out better than a standard Phillips, so fasteners seat to a consistent depth. Common in cabinetry, electronics enclosures, and European-manufactured equipment. Chrome-plated steel resists corrosion for long tool life in shop environments. These sockets conform to ISO 1174 and ISO 8764-1 for reliable fit with Pozidriv fasteners.
