KS Tools 911.5145 screwdriver bit socket Torx T45 30mm hexagon

The KS Tools 911.5145 screwdriver bit is a compact tool element engineered for precision fastening with a Torx T45 profile. With a 30 mm overall length and a hexagonal shank measuring 5/16 inch (127/16 mm), the bit fits many interchangeable bit holders and manual or powered drivers. Its lightweight construction (about 10 g) and precise Torx tip help deliver consistent engagement in recessed fasteners and confined work areas.

Advantages

The Torx T45 geometry ensures improved torque transfer and reduced cam-out compared with slotted or Phillips profiles. The 30 mm length offers a balance between reach and control for work in shallow recesses while maintaining stability. The hexagonal shank provides secure retention in compatible chucks and bit holders, enabling quick changes and compatibility with a wide range of screwdrivers and impact adapters. The small mass and compact size reduce user fatigue during repetitive tasks.

Suitable for

• Automotive maintenance and component assembly where Torx T45 fasteners are used
• Appliance repair and electronic housing removal requiring controlled torque
• Furniture assembly and mechanical installations with recessed Torx screws
• General workshop use with interchangeable bit systems and power drivers

Key specifications

• Tip type: Torx T45
• Length: 30 mm
• Shank style: Hexagonal
• Shank size: 5/16 inch (127/16 mm)
• Weight: approximately 10 g

How to use

Insert the hexagonal shank into a compatible bit holder, ratchet, or power driver until it seats firmly. Align the Torx T45 tip with the fastener recess, apply steady axial pressure, and turn the driver to tighten or loosen the screw. For best results, ensure the bit is clean and undamaged before use to maintain full engagement and reduce wear on both bit and fastener.

Recommendations

Use with appropriate torque settings on powered drivers to avoid fastener or bit damage. Store the bit in a dry place and inspect regularly for wear; replace when the tip shows rounding or deformation. Match the bit size precisely to the fastener to ensure safe and efficient operation.
