Socket wrench MILWAUKEE Hollowcore 13 mm, hollow shaft design for through-bolts

The MILWAUKEE Hollowcore 13 mm socket wrench features a hollow-shaft construction that allows the socket to fit over long studs and through-bolts. Engineered for situations where a conventional closed socket would be blocked by a protruding bolt or stud, this 13 mm hollowcore socket provides a standard fit for corresponding fasteners while permitting access to recessed or extended bolts without removing the stud. It is intended for mechanical, automotive and assembly tasks where long bolts are present and where a through-socket design improves workflow and reduces disassembly.

Advantages

The hollow-shaft design enables fastening and loosening of nuts located on extended studs or through-bolts without requiring removal of the stud, saving time and effort. The 13 mm dimension matches common fastener sizes, ensuring accurate engagement and torque transfer. Manufactured to MILWAUKEE quality standards, the socket is compatible with standard drive tools and offers reliable mechanical fit for repetitive use in workshop and field environments.

Suitable for

• Automotive repair where wheel hubs, engine mounts, or brake components use long studs
• Mechanical assembly and maintenance with through-bolts or extended threaded rods
• Industrial equipment service requiring access to recessed nuts on protruding studs
• General workshop tasks involving standard 13 mm fasteners and limited clearance

Key specifications

• Socket size: 13 mm
• Design: hollow-shaft (through-socket) to accommodate long studs and through-bolts
• Drive compatibility: fits standard socket drives (check tool drive size before use)
• Typical applications: mechanical, automotive, assembly, maintenance
• Material and finish: manufactured to professional tool standards for durability and corrosion resistance

How to use

Select a compatible drive tool and ensure the drive connection matches the socket. Slide the hollowcore socket over the protruding stud or through-bolt until it seats on the nut. Apply torque using a ratchet, breaker bar or torque wrench as required, keeping the drive and socket aligned to prevent rounding of the fastener. After loosening or tightening, withdraw the socket along the stud. Inspect the socket and fastener for wear after repeated heavy use.

Usage recommendations

Use appropriate personal protective equipment and ensure the correct torque settings for the fastener material; avoid using damaged sockets or incorrect drive sizes to prevent tool failure or fastener damage.
