Screwdriver bit Jonnesway D125T40A 1/4" Torx T40 x 25 mm

Jonnesway D125T40A is a 1/4" drive Torx screwdriver bit sized T40 with a length of 25 mm. It is manufactured to fit standard 6.35 mm (1/4") hex bit holders, ratchets and compatible electric drivers. The bit provides a precise Torx interface for fastening and maintenance work, offering consistent engagement with T40 fasteners in automotive, machinery and equipment service environments.

Advantages

The Jonnesway T40 x 25 mm bit is made to deliver accurate fit and reliable torque transfer when used with compatible tools. Its compact 25 mm length balances access in confined spaces with sufficient engagement depth. The standardized 1/4" hex shank enables quick changes in bit holders and impact-ready adapters, while the Torx geometry reduces cam-out and wear on both bit and fastener when correctly applied.

Suitable for (tasks / use cases)

• Automotive assembly and repair where T40 Torx fasteners are used
• Maintenance of machinery and industrial equipment
• Field service and on-site fastening tasks using ratchets or cordless drivers
• Electronics and appliance repair requiring controlled torque on T40 screws

Key specifications

• Drive type: 1/4" (6.35 mm) hex shank
• Tip type: Torx T40
• Length: 25 mm
• Compatibility: bit holders, ratchets and electric drivers that accept 1/4" bits
• Typical applications: fastening, maintenance, assembly

How to use

Insert the 1/4" hex shank into a compatible bit holder, ratchet or electric driver until it seats securely. Align the Torx T40 tip with the mating fastener and apply steady axial pressure while turning the tool to prevent slippage. For powered drivers, set the torque or clutch to an appropriate level for the material and fastener to avoid over-torquing. After use, remove the bit and store it in a bit holder or case to protect the tip profile.

Usage recommendations

Use the bit with tools that properly secure 1/4" bits and select the correct torque setting for the application. Replace the bit if the Torx tip shows signs of rounding or excessive wear to maintain fastener integrity and safe operation.
