US PRO 1634 9 Piece Extra Long Ball End Hex Key Set

The US PRO 1634 9 Piece Extra Long Ball End Hex Key Set is built for demanding fastening tasks where standard and long hex keys simply do not offer enough reach or leverage. Designed for professional technicians, maintenance teams, and serious DIY users, this extra long metric hex key set provides superior access, torque control, and durability in challenging working environments.

Extra Long Design for Deep and Restricted Access

The extended length of each hex key allows effortless access to fasteners positioned deep within housings, behind panels, or around obstructions. The increased leverage also helps reduce user effort when loosening stubborn bolts, making this set particularly effective for machinery maintenance, automotive repairs, fabrication, and industrial assembly work.

Ball End Flexibility with Secure Torque

Each key features a standard hex end on the short arm for maximum fastener engagement and torque transfer, ideal for breaking tight fixings free and final tightening. The ball end on the long arm enables operation at angles of up to approximately 30 degrees, allowing users to work efficiently where straight line access is not possible while reducing the risk of rounding fastener heads.

Built for Professional Durability

Manufactured from heat treated CR V chrome vanadium steel, the US PRO 1634 hex keys offer excellent resistance to twisting, wear, and fatigue during repeated use. The anti slip coated finish improves grip and control, especially when working with oily or greasy hands, while the multi coloured design allows instant identification of the correct size, helping maintain workflow efficiency in busy environments.

Organised and Ready for Daily Use

The set is supplied with a durable storage clip that keeps all nine keys securely organised and easy to access. This makes storage in toolboxes, drawers, or portable tool bags simple and efficient, ensuring the right tool is always close at hand.
