Socket wrench bit Milwaukee HollowCore 5 mm magnetic

Milwaukee HollowCore 5 mm magnetic socket wrench bit is engineered for fastening and loosening 5 mm nuts and bolts in situations where access is limited by long threaded rods or extended fasteners. The hollow-core design permits the bit to pass over protruding studs, while the integrated magnetic tip holds small fasteners in place for one-handed starts and accurate placement. It fits standard 1/4" hex bit holders and many impact drivers, making it suitable for workshop, assembly, maintenance, and repair tasks.

Advantages

The hollow-core construction provides clearance for long bolts and threaded rods without the need for socket adapters or extensions, reducing tool changes and saving time. The magnetic tip secures nuts and screws during insertion, improving control in tight spaces and when working overhead. Precision-machined engagement surfaces deliver a secure fit on 5 mm fasteners to minimize rounding and wear, and compatibility with standard bit holders and impact drivers ensures versatile use across handheld and powered tools.

Suitable for

• Fastening and loosening 5 mm nuts and bolts on machinery and equipment
• Assembly lines and production work where threaded rods protrude
• Maintenance and repair tasks in tight or recessed spaces
• Automotive and bicycle repairs requiring narrow access
• Overhead or single-handed installations where magnetic retention is beneficial

Key specifications

• Bit type: Hollow-core socket wrench bit
• Nominal size: 5 mm for nuts and bolts
• Tip feature: Integrated magnetic tip for fastener retention
• Drive compatibility: Standard 1/4" hex holders and compatible impact drivers
• Construction: Precision-machined steel for secure engagement and durability

How to use

Insert the 1/4" hex shank into a compatible bit holder, screwdriver, or impact driver. Slide the hollow-core bit over the threaded rod or bolt so the socket seats on the 5 mm fastener. Use the magnetic tip to hold the fastener in position while starting by hand if needed, then apply torque with the chosen tool. When using an impact driver, select appropriate torque settings and avoid prolonged high-torque impacts on worn fasteners to prevent damage.

Usage recommendations

Inspect the bit and fastener before use; replace the bit if deformation or excessive wear is present. For maximum life, avoid applying torque beyond the fastener’s specification and use an appropriate torque-limiting driver for precision assembly. Keep the magnetic tip free of metallic debris to maintain retention performance.
