Gearwrench 86540 3/8 Drive Metric Socket Set 28 Pc

Product Description

The GEARWRENCH 86540 is a 28-piece, 3/8 inch drive metric socket set covering sizes from 6mm to 19mm in both standard and deep configurations. Each socket is machined from alloy steel and finished in full-polished chrome for corrosion resistance and easy cleaning. The set includes 6-point sockets throughout, which grip fastener flats rather than corners to reduce rounding on worn or rusted hardware. Sockets are mounted on a rail for organized storage and quick identification on the job. This set suits licensed mechanics, HVAC technicians, plumbers, and electricians who need metric coverage for equipment installation and service work.

This socket set is suited for residential and commercial service environments where metric fasteners are standard. The combination of standard and deep sockets on a single rail covers both flush fasteners and recessed or studded applications without switching drive sets. The 6mm through 19mm range addresses the most common metric fastener sizes found on HVAC equipment panels, electrical enclosures, plumbing fixtures, and general mechanical assemblies. The compact rail format fits in a tool bag, service truck tray, or drawer organizer.

Installation Notes

Ensure the ratchet or drive tool is rated for the torque required by the fastener application before use. Do not use impact-rated tools with chrome-finish hand sockets unless the sockets are specifically rated for impact use. Store sockets on the included rail when not in use to prevent damage to the chrome finish and to maintain inventory. Consult equipment manufacturer torque specifications for critical fastener applications.
