Stanley STMT71651 Standard Socket Set 85 Pc

Product Description

The STANLEY STMT71651 is an 85-piece standard socket set covering both 1/4 inch and 3/8 inch drive sizes in a combined inch and metric range. Sockets span from 5/32 inch up to 7/8 inch on the inch side and 4 mm up to 19 mm on the metric side, all featuring a 6-point contact design for reduced fastener rounding. The chrome finish resists corrosion in shop and field environments. The set ships in a blow-molded case that organizes each piece and protects against damage during transport. Weighing 7.76 pounds, it is sized for a full-time toolbox or a service van. Licensed mechanics, HVAC technicians, plumbers, and electricians reach for this set for general fastener work across residential and light commercial service calls.

This socket set is suited for general mechanical and trade service work where both standard inch and metric fasteners are encountered on the same job. The dual-drive configuration lets a technician move between tight-clearance work on 1/4 inch drive and higher-torque applications on 3/8 inch drive without swapping to a second set. The blow-molded case makes it practical for organized storage in a service vehicle. The included ratchets, extensions, spinner handle, and bit holder socket reduce the need to source additional accessories for basic disassembly and reassembly tasks.
