Proto J52205 Metric Deep Socket Set 12pc 3/8 Drive

Product Description

The PROTO J52205 is a 12-piece metric deep socket set built for professional technicians who need extended reach on recessed or deeply set fasteners. The set uses a 3/8 inch drive and covers sizes from 8 mm through 19 mm, giving techs a full spread of common metric fastener sizes in a single kit. Each socket is machined to a 6-point design for maximum contact on hex fasteners, and the chrome finish resists corrosion in shop and field environments. Licensed HVAC technicians, plumbers, electricians, and mechanical contractors reach for deep socket sets when standard-depth sockets cannot fully seat on long studs or deeply countersunk bolts.

This set is suited for residential and light commercial service work where metric fasteners are standard. Deep sockets are commonly used when removing and installing motor mounts, pipe flanges, panel hardware, and equipment access components. The 8 mm to 19 mm size range covers the fastener dimensions found on most mechanical equipment enclosures, junction boxes, and structural hardware. The 3/8 inch drive pairs with a wide range of ratchets, extensions, and flex handles already in most service technicians' kits.

Key Features

• 12-piece metric set covering 8 mm through 19 mm in a single kit
• 3/8 inch drive compatible with standard ratchets and drive accessories
• 6-point socket design maximizes contact and reduces fastener rounding
• Deep socket profile reaches recessed and long-stud fasteners that standard sockets cannot
• Chrome finish provides corrosion resistance for shop and field use

Compatibility

Designed for use with any standard 3/8 inch drive ratchet, extension bar, or torque wrench accepting metric deep sockets.

Installation Notes

Deep socket sets are used by licensed trades and general service technicians across HVAC, plumbing, electrical, and mechanical disciplines. Always confirm the fastener size before seating the socket to avoid slippage and fastener damage. Use an appropriate torque wrench when fastener torque requirements are specified by the equipment manufacturer. Inspect sockets for cracks or deformation before each use and remove any damaged piece from service.
