Socket bit 1/2" Topex 17 mm hex long 38D756

The Topex Socket bit 1/2" 17 mm hex long (38D756) is a long hex socket designed for use with 1/2-inch drive ratchets and torque tools. Its extended length and hexagonal profile allow access to recessed or hard-to-reach fasteners while maintaining a secure fit on 17 mm hex heads. The design suits tasks where standard short sockets cannot reach, providing added clearance in deep bores, behind panels, or inside assemblies.

Advantages

This long hex socket bit offers enhanced reach while preserving torsional strength for reliable torque transfer. The 1/2" drive interface ensures compatibility with common ratchets and torque wrenches used in professional and hobby workshops. Its precise 17 mm hex geometry reduces rounding of fastener corners and improves grip during loosening or tightening operations.

Suitable for

• Automotive repairs where bolts are recessed or located in tight engine compartments
• Machinery maintenance and industrial equipment servicing
• General workshop tasks involving deep-set hex fasteners
• Assembly and disassembly of appliances and metalwork with restricted access

Key specifications

• Drive size: 1/2 inch
• Socket profile: 6-point hex
• Nominal head size: 17 mm
• Overall length: extended/long type for deep access
• Material and finish: hardened steel construction with protective coating for wear resistance

How to use

Select the 17 mm long hex socket bit and attach it securely to a compatible 1/2" drive ratchet or torque wrench. Insert the socket onto the fastener head, ensuring full engagement of the hex profile before applying torque. Use steady, controlled force to avoid slippage; when using a torque tool, follow the required torque specification for the fastener. Retract the socket from the workpiece after loosening or tightening, and store it in a protective case to prevent damage.

Usage recommendations

Inspect the socket and fastener for wear or damage before each use. For high-torque applications, use a calibrated torque wrench and avoid impact tools unless the socket is rated for impact use. Keep the socket clean and lightly lubricated to prevent corrosion and ensure long service life.
