Product Description

The WERA 05003181001 is a 7-piece hex bit socket set built for 3/8 inch drive tools. Manufactured from chrome vanadium steel with a chrome-plated finish, this set covers metric hex sizes from 4mm to 10mm. It is suited for fastener-removal and installation tasks in HVAC equipment, plumbing fixtures, electrical enclosures, and general mechanical service work. The seven individual sockets cover the most common metric hex fastener sizes encountered in field and shop environments. Licensed technicians and experienced tradespeople who rely on 3/8 inch drive setups will find this set a direct fit for their existing ratchets and extensions.

This set is intended for use in professional trade environments where metric hex fasteners are common. Typical applications include service and repair of HVAC equipment panels, pump assemblies, motor mounts, and electrical enclosures.

Installation Notes

Hex bit sockets are installed and removed by hand onto a 3/8 inch drive ratchet or torque wrench. Ensure the drive tool is rated for the torque required by the fastener application before use. Inspect sockets for wear or cracking before each use and replace any damaged socket immediately. No power-down or lockout procedure is required for the sockets themselves, but always follow appropriate lockout/tagout procedures on any equipment being serviced.
