Gearwrench 82554 Hex Bit Socket Set 3/8 Drive 6 Pc Metric

Product Description

The GEARWRENCH 82554 is a 6-piece metric hex bit socket set built for 3/8 inch drive ratchets and extensions. The set covers hex sizes from 4 mm through 10 mm, giving technicians the most common metric internal-hex fastener sizes in a single organized package. Bits are machined from S2 steel for impact-grade toughness and finished in chrome for corrosion resistance. The sockets mount on a storage rail that keeps the set organized in a tool chest drawer or service bag. Designed for professional-grade fastener work in HVAC, plumbing, electrical, and general mechanical service.

This set is appropriate for residential and light commercial service applications where metric hex-head fasteners are common. Typical uses include equipment panel fasteners, motor mount bolts, valve assemblies, and access cover hardware across HVAC equipment, pumps, and electrical enclosures. The 3/8 inch drive size is the standard choice for mid-torque applications in confined service areas. Individual sizes included are 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, and 10 mm.

Installation Notes

Install and remove using a 3/8 inch drive ratchet or torque wrench appropriate to the fastener specification. De-energize electrical equipment and shut off gas or fluid supply before breaking fasteners on live systems. Confirm the correct hex size seats fully in the fastener recess before applying torque to avoid rounding the socket or fastener head. Follow applicable codes including NEC, IFGC, and IPC when servicing trade equipment.
