Proto J52332AS 32 Pc Socket Set 3/8 Drive Sae Metric

Product Description

The PROTO J52332AS is a 32-piece socket set built around a 3/8-inch drive and covering both SAE and metric sizing. SAE sockets range from 1/4 inch through 7/8 inch, with metric coverage extending to 20 mm. All sockets use a 12-point configuration, which provides multiple contact points on fastener heads and allows work in tight spaces with limited swing angle. This set is suited for HVAC technicians, plumbers, electricians, and mechanical contractors who need a compact, dual-standard socket assortment for equipment installation and service work.

This socket set is appropriate for residential and light commercial service applications where both SAE and metric fasteners are encountered. Common use cases include equipment mounting, panel work, and mechanical connections on HVAC units, electrical enclosures, and plumbing fixtures. The 3/8-inch drive size balances torque capacity and compactness, making it practical for confined equipment spaces. The 32-piece count provides enough coverage for a wide variety of fastener sizes without requiring multiple separate sets on the job.

Installation Notes

This socket set is used by licensed tradespeople across HVAC, plumbing, electrical, and general mechanical service work. Before beginning any service, de-energize electrical equipment and shut off fluid or gas supplies as required by applicable codes. Inspect each socket for cracks or wear before applying torque to critical fasteners. Do not use impact-rated tools with sockets not rated for impact service.
