Socket bit Torx 1/2" Jonnesway T40 x 100 mm S07H4340

Jonnesway Socket bit Torx 1/2" T40 x 100 mm (S07H4340) is a 1/2" drive Torx socket designed for T40 fasteners with an extended 100 mm shank. It is intended for use with 1/2" ratchets, extensions and compatible impact drivers and provides extra reach for recessed Torx screws and bolts in automotive, industrial maintenance and machinery work. The bit features hardened steel construction for wear resistance and a precisely machined Torx profile for secure engagement with fastener heads.

Advantages

The extended 100 mm length increases accessibility to fasteners located in deep or confined spaces while maintaining a stable connection to a 1/2" drive tool. Hardened steel construction and precision machining reduce rounding of Torx heads and improve service life under repeated use. The standard 1/2" drive interface ensures compatibility with common hand and power tools used in workshops and maintenance environments.

Suitable for

• Automotive repair and maintenance where recessed T40 fasteners are present
• Industrial machinery servicing and assembly tasks
• Maintenance work in confined or hard-to-reach locations
• Use with 1/2" ratchets, extensions and impact drivers that accept 1/2" sockets

Key specifications

• Drive size: 1/2"
• Torx size: T40
• Shank length: 100 mm
• Material: hardened steel
• Compatibility: designed for use with 1/2" ratchets, extensions and compatible impact tools

How to use

Select a 1/2" drive ratchet, extension or impact driver compatible with socket bits and attach the Torx socket to the tool's square drive. Align the Torx bit with the T40 fastener head and apply steady torque while keeping the tool square to the fastener to avoid cam-out. For recessed or hard-to-reach fasteners, use the full 100 mm length to reach the fastener while maintaining control of the driving tool. Inspect the Torx profile before use and replace the bit if excessive wear or deformation is visible.

Usage recommendations

When using with power impact tools, select appropriate torque settings and safety equipment. For best results on high-torque or rusted fasteners, use a suitable penetrating lubricant and consider using a longer extension or universal joint only if required to prevent side loading on the bit.
