Screwdriver bit Wera 05066488001 — Torx TX25, 25 mm, hexagonal 3/8" shank

Wera screwdriver bit 05066488001 is a single-piece Torx TX25 tip bit with a 25 mm overall length and a hexagonal 3/8" shank designed for secure seating in compatible sockets and bit holders. The bit is intended for engagement with recessed TORX® fasteners and is manufactured to provide a hard, wear-resistant contact surface suitable for assembly, maintenance and repair operations. Its compact form factor allows use in confined spaces and with common bit holders, drivers and compatible power tools.

Advantages

The bit offers a Torx TX25 geometry that ensures precise fit and reduced cam-out on matching fasteners. Constructed as a single-piece bit with an extra-hard working tip, it provides improved wear resistance and longevity under repeated use. The hexagonal 3/8" shank delivers secure clamping in sockets and holders, minimising slippage during torque application. The compact 25 mm length makes the bit convenient for tight spaces while remaining compatible with standard holders designed to accept hexagonal bits.

Suitable for

• Assembly of components with Torx TX25 recessed screws
• Maintenance and repair tasks on appliances, electronics and machinery that use TX25 fasteners
• Use in tight or confined work areas where a short bit length is required
• Work with sockets, bit holders and drivers that accept a 3/8" hexagonal shank

Key specifications

• Tip profile: Torx TX25
• Length: 25 mm
• Shank type: hexagonal 3/8"
• Construction: single-piece bit
• Tip hardness: extra-hard working tip for improved wear resistance
• Intended fastening: recessed TORX® screws

How to use

Insert the hexagonal 3/8" shank of the bit into a compatible socket, bit holder or driver until it seats securely. Select a driver or power tool with appropriate torque settings for the fastener and material being worked on. Align the Torx TX25 tip with the matching recessed screw head and apply steady axial pressure while turning to engage the fastener. For power tools, use controlled speed and torque to avoid cam-out or damage to the screw head. Remove the bit after use and inspect the tip for wear before subsequent applications.

Usage recommendations

Use the bit with holders and drivers that accept 3/8" hexagonal shanks and set torque appropriately for the fastener and material. Replace the bit if the Torx profile shows rounding or significant wear to maintain proper engagement and reduce risk of fastener damage.
