Wera 05022630001 Hex Key Long Arm 5/64 Inch

Product Description

The WERA 05022630001 is a long-arm hex key designed for driving hex socket fasteners in tight or recessed applications. The 5/64-inch hex tip engages socket head cap screws and set screws where standard-length keys lack reach. Built from cast steel, this tool delivers the torsional strength needed for repetitive fastening tasks in mechanical assembly, equipment maintenance, and manufacturing environments. The long arm measures 4 inches overall, with a short arm of 1 inch, giving the technician two working orientations. Tradespeople, millwrights, and maintenance mechanics reach for this key when access depth or torque angle dictates a longer reach than a standard key provides.

This hex key suits residential and commercial service work wherever hex socket fasteners are encountered. Typical applications include HVAC equipment assembly and service, electrical panel work, pump and motor maintenance, and general mechanical repairs. The ice blue handle provides quick visual identification in a tool pouch or set. The 5/64-inch size covers common set screw and fastener sizes found on shaft collars, pulleys, and small mechanical components across a broad range of trade and industrial equipment.

Key Features

• 5/64-inch hex tip for socket head cap screws and set screws
• Long-arm design at 4 inches overall length for extended reach into recessed fastener locations
• Cast steel construction for durability and torsional strength under repeated use
• Short arm measures 1 inch for high-torque driving in the alternate orientation
• Ice blue handle color for quick identification in tool storage
• Inch measurement system; 5/64-inch size fits standard SAE fasteners

Compatibility

Designed for use with 5/64-inch hex socket fasteners in SAE inch-standard applications across mechanical, HVAC, plumbing, and electrical service work.

Installation Notes

Install and remove hex fasteners by selecting the correct hex size before applying torque to avoid rounding the socket. Inspect the hex tip for wear or deformation before use, as a damaged tip can damage fastener sockets. For high-torque applications, use the short arm for driving and the long arm for access in confined spaces. Follow equipment manufacturer lockout/tagout procedures before servicing any powered equipment.
