Socket wrench bit (hollowcore) MILWAUKEE 5.5 mm magnetic

Hollowcore socket wrench bit MILWAUKEE 5.5 mm magnetic is a 5.5 mm socket-style bit designed for fastening tasks where a hollow construction and magnetic tip help retain fasteners. It fits standard bit holders and drivers and is intended for assembly, maintenance and repair work that requires secure screw or bolt engagement in confined spaces or through-hole applications.

Advantages

The hollowcore design allows the bit to pass over protruding threaded shafts or long fasteners, reducing the need to reposition parts. A magnetic tip holds screws and small bolts in place during insertion and extraction, improving one-handed operation and reducing dropped fasteners. Manufactured by MILWAUKEE to typical industrial standards, the bit combines socket-style engagement with compatibility for common hex chucks and quick-change holders, enabling reliable torque transfer and a consistent fit with compatible drivers.

Suitable for

• Assembly of components with long bolts or studs that extend beyond the nut
• Maintenance and repair work in confined or hard-to-reach areas
• Through-hole fastening where access behind the fastener is limited
• Use with power drivers, impact drivers (if specified safe by manufacturer), and manual bit holders

Key specifications

• Bit type: hollowcore socket-style bit
• Effective tip size: 5.5 mm
• Magnetic tip for retaining fasteners
• Compatibility: standard hex bit holders and drivers
• Intended use: fastening screws and small bolts in through-hole or confined applications

How to use

Select a compatible bit holder or driver and insert the hollowcore socket bit until it seats securely. Engage the fastener so that the magnetic tip holds it in place, then apply steady torque with the driver. For through-hole applications, slide the hollowcore bit over the protruding shaft or stud until the socket engages the nut or fastener head. Withdraw the bit straight to avoid dislodging retained fasteners.

Usage recommendations

Inspect the bit before each use for wear or damage. Use the bit with drivers and accessories rated for the intended torque and follow safety guidance for power tools. Avoid using a hollowcore socket bit on oversized or damaged fasteners and replace the bit when magnetic retention or fit becomes compromised.
