Wera 05023450001 Metric Hex Key Set Long Arm 7 Piece

Product Description

The WERA 05023450001 is a 7-piece metric hex key set built for trade professionals who need reliable, long-arm Allen wrenches across a broad size range. The set spans 2.5 mm through 10 mm, covering the most common fastener sizes encountered in HVAC equipment panels, electrical enclosures, plumbing fixture assemblies, and general mechanical service work. The long arm style provides extended reach into recessed fasteners and delivers greater torque leverage compared to standard-length keys. At 2.47 pounds, this is a substantial, tool-grade set intended for daily field and shop use.

This hex key set is suited for residential and light commercial service applications where metric fasteners are standard. HVAC technicians will find the size range practical for accessing blower motor mounts, control board brackets, and equipment access panels. Electricians and plumbers working on imported equipment or metric-fastened fixtures will appreciate having 2.5, 3, 4, 5, 6, 8, and 10 mm keys in a single organized set. The long arm design also allows use of the short end for higher torque on stubborn fasteners.

Installation Notes

Select the correct key size before applying torque to avoid rounding fastener sockets. Power down or de-energize equipment before accessing internal fasteners on electrical or HVAC systems. Use the short arm end when higher torque is needed and the long arm end for reach into deep or obstructed fastener locations. Inspect keys for wear or deformation before use and do not use damaged keys on precision fasteners.
