Proto J47200 Metric Socket Set 12pc 1/4 in Drive 4-14mm

Product Description

The PROTO J47200 is a 12-piece metric socket set built for professional trade use in HVAC, plumbing, electrical, and general mechanical service work. The set uses a 1/4 inch drive and covers sizes from 4mm to 14mm in a 6-point configuration. The 6-point design reduces fastener rounding under torque, which matters when working in tight equipment cabinets or mechanical rooms. At 0.58 pounds total, the set is compact and easy to carry to a job site or keep in a service bag. Licensed tradespeople and experienced technicians will find this set useful for equipment access panels, control board mounting hardware, and small fastener work across a wide range of service calls.

This socket set is suited for residential and light commercial service applications where 1/4 inch drive metric fasteners are common. Typical uses include tightening and loosening mounting hardware on HVAC components, electrical enclosures, pump assemblies, and other mechanical equipment that uses smaller metric fasteners. The 4mm to 14mm range covers the majority of small metric hardware found on modern equipment. The 6-point sockets provide a secure grip on hex fasteners, making the set a reliable choice for production service environments where speed and accuracy are both required.
