Hex Socket Bit 1/4" 7 mm Topex Superlock long (model TOP-08-240)

Long hex socket bit for 1/4" drive in 7 mm size from the Topex Superlock range. The extended shank provides additional reach for fastening and loosening hex-head fasteners located in deep, recessed or hard-to-reach areas. This bit is compatible with 1/4" ratchets, bit holders and screwdriver handles that accept 1/4" bits, and is intended for general mechanical, automotive and DIY use where a longer reach and reliable engagement with hex fasteners are required.

Advantages

The Topex Superlock long 7 mm hex socket bit combines an extended shank length with a 1/4" drive interface to deliver improved access in confined spaces. Its hex geometry ensures secure engagement with fastener heads to reduce slipping and rounding. The long design allows work on deep-set fasteners without the need to disassemble surrounding components, and compatibility with common 1/4" holders and ratchets makes it versatile across toolkits.

Suitable for

• Reaching recessed hex-head fasteners in automotive maintenance
• Tight or deep assembly points in construction and carpentry
• DIY repairs and installations requiring extended reach
• Use with 1/4" bit holders, ratchets and screwdriver handles

Key specifications

• Drive interface: 1/4" (6.35 mm) compatible drive
• Bit type: Hex (Allen) socket
• Bit size: 7 mm across flats
• Shank: long/extended length for increased reach
• Use case: manual and ratchet-driven fastening
• Material: hardened steel construction suitable for torque transmission

How to use

Select a compatible 1/4" holder or ratchet and insert the long 7 mm hex socket bit until it locks securely. Position the socket over the hex-head fastener and apply steady turning force, keeping the bit aligned with the fastener axis to minimize cam-out. For bolts recessed in tight spaces, use the extended reach to access the fastener while maintaining control; when torque requirements are high, use a ratchet or appropriate driver rated for the required torque.

Usage recommendations

Inspect the bit for wear or damage before use and replace if the hex profile rounds. Use appropriate eye protection and workspace lighting when working in confined areas. Avoid excessive bending forces on the long shank; if a higher torque is needed, choose a shorter, stronger socket or a tool specifically rated for impact or high-torque applications.
