US PRO 1633 9 Piece Long Ball End Hex Key Set

The US PRO 1633 9 Piece Long Ball End Hex Key Set is designed for professionals who require extended reach, improved leverage, and flexible access when working with recessed or obstructed fasteners. Built for everyday workshop, automotive, and maintenance use, this long length metric hex key set delivers the control, strength, and reliability needed for demanding applications where short keys are not sufficient.

Extended Length for Improved Reach and Control

The long arm design allows easier access to deep seated bolts and fixings positioned behind panels, inside housings, or around surrounding components. The added length provides improved leverage and smoother control, reducing user effort when loosening stubborn fasteners or tightening bolts accurately in hard to reach locations.

This makes the set especially suitable for machinery maintenance, automotive repairs, fabrication work, and general engineering tasks where access is limited but precision is essential.

Ball End Flexibility with Secure Fastening

Each hex key is engineered with a standard hex end on the short arm for direct engagement and maximum torque transfer. This end is ideal for breaking fasteners loose or performing final tightening where full contact is required.

The ball end on the long arm allows the key to operate at angles of up to approximately 30 degrees, enabling fastening where straight line access is not possible. This angled capability improves efficiency and helps reduce the risk of rounding fastener heads when working around obstacles or in awkward positions.

Durable Construction for Professional Use

Manufactured from heat treated CR V chrome vanadium steel, the US PRO 1633 hex keys are built for strength, toughness, and long service life. The heat treatment process enhances resistance to twisting and wear, ensuring dependable performance during repeated use in busy workshop and maintenance environments.

The anti slip coated finish improves grip and handling, particularly when working with oily or greasy hands, while the multi coloured coating allows quick and accurate size identification. This colour coding helps reduce downtime and improves workflow efficiency when switching between sizes during jobs.

Organised and Ready for Work

To keep tools neat and accessible, the set is supplied with a durable storage clip that securely holds all nine hex keys together. This ensures easy storage in toolboxes, drawers, or portable tool bags, keeping the correct size close at hand when needed.
