Proto J52325S 25 Pc 3/8 Drive 6 Point Sae Socket Set

Product Description

The PROTO J52325S is a 25-piece, 3/8-inch drive socket set designed for professional-grade fastener work across mechanical, HVAC, plumbing, and electrical service applications. The set covers a SAE range from 3/16 to 3/4 inches and features 6-point socket geometry throughout, which reduces the risk of rounding fastener heads under high torque. At 3.37 pounds, the kit is compact enough for a service bag while covering the most common fastener sizes encountered in trade fieldwork. The set ships as a single packaged unit.

This socket set suits residential and light commercial service work where a 3/8-inch drive is the standard — including equipment access panels, motor mounts, bracket hardware, and utility connections. The SAE sizing range from 3/16 to 3/4 inches covers the fastener spectrum found on most mechanical equipment in the field. Licensed technicians and journeyman-level tradespeople carrying a 3/8-inch drive ratchet will find this set a practical bench or van staple.

Key Features

• 25-piece set spanning 3/16 to 3/4 inches SAE
• 3/8-inch drive compatibility across all sockets
• 6-point socket design reduces fastener rounding under load
• Compact packaged dimensions: 10 inches long, 8 inches wide, 1.6 inches tall
• Lightweight kit at 3.37 pounds for field portability

Compatibility

Designed for use with any standard 3/8-inch drive ratchet, extension, or torque wrench. The SAE sizing range makes this set a general-purpose fit for common fastener sizes found on mechanical and HVAC equipment.

Installation Notes

Hand tools of this type require no special certification to use, but always ensure the correct socket size is fully seated on the fastener before applying torque to avoid rounding. When servicing live electrical or refrigerant-bearing equipment, de-energize the system and recover refrigerant per EPA Section 608 requirements before breaking any mechanical connections. Inspect sockets for cracks or wear before use on high-torque fasteners.
