Socket wrench MILWAUKEE Hollowcore 8 mm — hand tool for hex fasteners

MILWAUKEE Hollowcore 8 mm socket wrench is a single-size hand socket engineered for tightening and loosening 8 mm hex fasteners. The hollowcore design allows the socket to fit over long studs and bolts, providing access in applications where a closed-end socket would not reach. The socket is compatible with standard 1/4" drive tools and extensions, making it suitable for confined spaces and mechanical assemblies where reach and clearance are required.

Advantages

The hollow design permits use on fasteners seated on protruding threads, reducing the need to remove studs or cut bolts. Compatibility with 1/4" drive tools ensures ease of integration with common ratchets and torque adapters. The single-size construction provides a precise fit for 8 mm hex heads, minimizing rounding and slippage when used with appropriate technique.

Suitable for

• Automotive repairs where long studs or through-bolts are present
• Maintenance work on machinery with protruding fasteners
• Assembly and disassembly of components in tight or recessed locations

Key specifications

• Drive compatibility: 1/4" (6.35 mm) drive
• Socket size: 8 mm hex
• Design: hollowcore to accommodate long studs/bolts
• Application: hand-operated socket for tightening and loosening hex fasteners

How to use

Select a compatible 1/4" drive ratchet or extension and position the hollowcore socket over the fastener so the socket fully engages the hex profile. Turn the ratchet or driver in the required direction to tighten or loosen the fastener, applying steady, controlled force to avoid rounding the hex head. When working over studs, slide the socket down until it seats against the nut or head, ensuring the protruding threads pass through the hollow center.

Usage recommendations

Inspect the hex fastener and the socket for wear before use. Use appropriate torque settings when tightening to prevent damage to the fastener or assembly. Store the socket in a dry place and keep it with complementary 1/4" drive tools to ensure proper fit and ease of access.
