Nut driver bit King Tony 75A112M, 66 mm length, 98.8 g

King Tony 75A112M nut driver bit is a compact hex driver designed for fastening and loosening nuts and hex fasteners in mechanical, electrical and maintenance work. The bit has a length of 66 mm and a weight of 98.8 g, making it easy to handle in confined spaces while providing the reach needed for recessed fasteners. Manufactured from chrome-vanadium alloy steel with an anti-rust oiled, sand-blasted finish, the bit is intended for repeated use and resistance to surface corrosion. A threaded-rod socket and automatic locking cams support secure engagement with fasteners without damaging threads when used correctly.

Advantages

The chrome-vanadium construction delivers a balance of hardness and toughness to withstand torque during tightening and loosening operations. The anti-rust oiling and sand-blasted surface improve corrosion resistance and reduce wear from frequent use. The threaded-rod socket and automatic locking cams enable quick, reliable capture of rod ends and hex fasteners, speeding up repetitive tasks. Its 66 mm length offers additional reach while remaining compact enough for work in tight assemblies.

Suitable for

• Mechanical assembly and disassembly of machines and equipment
• Electrical installations where compact hex drivers are needed
• Maintenance and repair tasks in workshops, service vehicles, and plants
• Applications requiring safe handling of threaded rods and hex nuts

Key specifications

How to use

Select a compatible bit holder or driver that accepts standard nut driver bits and insert the King Tony nut driver bit until it seats securely. Align the threaded-rod socket or hex opening with the fastener, engage the automatic locking cams if present to capture the fastener, and apply torque using a manual driver or powered driver within the tool’s recommended limits. Retract the bit after loosening or finishing the fastening operation and inspect the threads and bit tip for wear before subsequent use.

Usage recommendations

Use appropriate torque settings and avoid excessive force to preserve the bit’s tip geometry and avoid damaging fastener threads. Keep the bit clean and lightly oiled if stored in humid environments to maintain the anti-rust protection. Replace the bit if significant wear or deformation is observed.
