Wera 05021728001 13 Piece L-key Hex Ball End Combo Set

Product Description

The WERA 05021728001 is a 13-piece L-handle hex and ball end combo key set covering a hex size range of 0.050 to 3/8 inch. Each key is machined from alloy steel and features a long-arm L-handle design with an overall length of 8.50 inches. The set ships in a caddy for organized storage and quick size identification on the bench or in the van. Mechanical technicians, HVAC installers, electricians, and plumbers reach for this set when working fasteners on equipment panels, motor mounts, valve packing glands, and electrical enclosures where a dedicated hex driver is not practical.

This set is suited for residential and light commercial service work where both standard hex drive and ball end access are needed in a single kit. The ball end tips allow engagement at an offset angle, useful when fastener access is partially obstructed. The caddy organizer keeps all 13 keys sorted by size and prevents loss on a busy job site. It covers the full inch range most commonly encountered on HVAC equipment, plumbing fixtures, and electrical hardware from 0.050 inch up through 3/8 inch.

Installation Notes

Select the correct hex key size before applying torque to avoid rounding fastener sockets. Ensure fasteners are fully engaged with the key tip before turning, particularly when using the ball end at an angle. Store keys in the caddy after use to maintain the set and prevent size mix-ups on the next call.
