Key specifications
Tip profile: Torx size 1
Total length: 89 mm
Shank diameter: 1/4" (standard bit shank)
Compatibility: fits 1/4" bit holders and power drivers
Packaging: single piece
How to use
Insert the 1/4" shank into a compatible bit holder, quick-release chuck or the screwdriver’s bit receptacle until it seats securely. Align the Torx 1 tip with the corresponding fastener head and apply steady axial pressure while turning the driver to avoid slippage. For power drivers, select an appropriate torque setting to prevent over-tightening small Torx fasteners. After use, store the bit in a protective case or bit organizer to protect the tip geometry.
Usage recommendations
Use the bit with properly sized Torx 1 fasteners and avoid excessive side load to preserve tip shape. When using powered tools, set torque limits appropriate for small fasteners to reduce the risk of damage to the fastener or workpiece.
