Screwdriver Bit Makita B-63703 2 pcs Torx T40 25 mm

The Makita B-63703 2 pcs Torx T40 25 mm screwdriver bits are precision-engineered accessories designed for reliable fastening. Each bit measures 25 mm in length and is shaped to the Torx T40 profile to ensure proper engagement with compatible fasteners. Supplied as a two-piece set, these bits are intended for use with screwdrivers, bit holders, and impact drivers that accept standard 1/4" hex shanks.

Advantages

These Torx T40 bits offer consistent tip geometry for secure seating and reduced cam-out during torque application. Manufactured to handle frequent use, they provide dimensional accuracy for repeatable performance and fit. The 25 mm length balances access and control, allowing work in moderately recessed fasteners while maintaining driver stability.

Suitable for

• Assembly and disassembly of Torx T40 fasteners in furniture and cabinetry
• Automotive interior and trim fastening tasks requiring T40 engagement
• Maintenance and repair tasks where moderate bit length is needed

Key specifications

• Bit type: Torx T40
• Quantity: 2 pieces per set
• Length: 25 mm
• Shank form: 1/4" hex-compatible
• Intended use: manual and powered drivers including impact drivers (check tool compatibility)

How to use

Insert a bit into a compatible bit holder or directly into the screwdriver chuck until it seats securely. Align the Torx T40 tip with the fastener recess and apply steady axial pressure while operating the driver at an appropriate speed and torque setting. For powered use, start at low speed to ensure correct engagement, then increase speed as needed. Remove the bit by withdrawing it from the holder after use and inspect the tip for wear before storage.

Usage recommendations

Use the bits with tools rated for the intended application, and select torque settings that match the fastener and material to avoid damage. Replace bits when tip wear or rounding is visible to maintain safe, effective fastening.
