Stanley 85-388 Deep Standard Socket Set 21 Pc 1/4 in

Product Description

The STANLEY 85-388 is a 21-piece deep and standard socket set built for professional technicians who need a compact, versatile 1/4 inch drive solution. The set covers a size range of 3/16 inch through 1/2 inch and includes both 9 standard and 7 deep 6-point sockets, giving access to fasteners in tight or recessed locations. A chrome finish resists corrosion and makes cleanup straightforward on the job. The set ships with a ratchet, spinner handle, two extensions, and a universal joint, making it a self-contained kit for service work across HVAC equipment, plumbing fixtures, and electrical panels.

This socket set is suited for residential and light commercial service environments where a 1/4 inch drive is the appropriate torque range. The deep sockets handle longer bolts and studs common in equipment access panels, motor mounts, and valve assemblies. HVAC technicians, plumbers, and electricians will find the included accessories particularly useful for working in confined equipment cabinets. The 6-point design reduces the risk of rounding fasteners compared to 12-point alternatives, which matters on corroded or worn hardware in the field.
