Proto J5206MH 6mm 6-point 3/8 Drive Hand Socket

Product Description

The PROTO J5206MH is a 6 mm, 6-point hand socket built for professional-grade fastener work. Machined from alloy steel with a chrome finish, this standard-length socket fits a 3/8 inch drive and delivers clean, precise engagement on hex fasteners. At 1-3/64 inches overall length and 0.05 pounds, it is compact and lightweight without sacrificing durability. Manufactured to ASME B107.110-2012 standards, the J5206MH is a reliable choice for mechanics, maintenance technicians, and tradespeople who need consistent performance across high-cycle applications.

This socket is suited for general mechanical and maintenance work where a 6 mm fastener and a 3/8 inch drive tool are the standard combination. Typical applications include equipment assembly, HVAC component fastening, electrical panel hardware, and plumbing fixture work. The 6-point design reduces the risk of rounding fastener heads compared to 12-point alternatives, making it well-suited for both new installation and service work on existing equipment.

Key Features

Compatibility

Designed as a standard 3/8 inch drive hand socket compatible with 3/8 inch drive ratchets, torque wrenches, and extensions from major tool manufacturers.

Installation Notes

Install and remove using a calibrated torque wrench when fastener torque specifications are critical. Ensure the drive tool and socket are fully seated before applying force to avoid slippage or fastener damage. Inspect the socket for wear or cracks before each use, and remove from service if the drive square or socket walls show signs of deformation.
