Socket Bit Torx Long 1/2" Proxxon T40 100mm

Long Torx socket bit for 1/2" drive by Proxxon, model T40 with a length of 100 mm. Designed to reach recessed or deep-set Torx fasteners, this 1/2" Torx long bit provides extended access where standard sockets cannot. The bit combines a long shank with a precise T40 Torx profile to ensure stable engagement and reduced cam‑out when working on automotive, machinery and equipment maintenance tasks.

Advantages

The Proxxon 1/2" T40 100 mm long Torx socket bit offers increased reach for recessed fasteners and a secure fit to minimise stripping. Its hardened tip maintains the Torx profile under torque, while the elongated chrome-vanadium or similar alloy shank (hardened and tempered) resists bending during use. The bit is compatible with standard 1/2" sockets and breakers, enabling use with ratchets, extensions and torque tools for controlled tightening and loosening.

Suitable for

• Accessing recessed or deep-set T40 Torx screws in automotive repair
• Maintenance and assembly of machinery and industrial equipment
• Workshops and hobby projects requiring extended reach Torx engagement
• Use with 1/2" ratchets, torque wrenches and breaker bars

Key specifications

• Torx size: T40
• Overall length: 100 mm
• Shank type: long straight shank for deep access
• Material and treatment: hardened tip with tempered alloy shank for durability
• Fit: designed for secure Torx engagement to reduce cam‑out

How to use

Select the Proxxon T40 long Torx bit and insert it into a compatible 1/2" socket or adapter. Fit the assembly to a ratchet, torque wrench or breaker bar as required. Insert the Torx tip fully into the fastener recess to ensure full seating of the profile before applying torque. Use steady, controlled force appropriate to the fastener and application; when tightening with a torque wrench, observe the required torque setting. After use, clean the bit and store it in a dry tool case to preserve the hardened surfaces.

Usage recommendations

Use the bit only with 1/2" drive tools and avoid excessive side loading to prevent bending. For high-torque applications, use a calibrated torque wrench and ensure the Torx profile is free of debris. Replace the bit if wear or rounding of the tip is observed to maintain safe and effective engagement.
