Premium S2 tool steel hex key insert bit for driving 1/8" hex socket head cap screws and Allen head fasteners. The 1/4" hex shank fits all standard power drills, impact drivers, and bit holders. At 1" overall length, this stubby insert bit reaches into tight spaces where a longer power bit will not seat.

• Hex size: 1/8"
• Overall length: 1"
• Shank: 1/4" hex (universal insert-bit standard)
• Material: S2 tool steel hardened to 58-62 HRC for high torque without rounding
• Best use: #6-#8 SHCS, bicycle stem and brake hardware, light machinery, furniture assembly
• Manufacturer part: Century Drill & Tool 68458

Tip: Insert bits cam out instantly under angled load. Seat the bit fully in the fastener and keep the driver square to the screw axis. For repeated driving, step up to a longer power bit with a torsion zone to extend bit life.
