Proto J5017MH Deep Hand Socket 17mm 3/8 Drive 6-point

Product Description

The PROTO J5017MH is a 17 mm deep hand socket designed for 3/8 inch drive ratchets and breaker bars. It features a 6-point internal geometry that delivers full-face contact on fastener flats, reducing the risk of rounding under torque. The chrome-plated finish resists corrosion and simplifies surface cleaning after use. At 2.8 inches in length, the deep profile provides the reach needed to seat on recessed or stud-mounted fasteners that a standard-length socket cannot engage. This socket is suited for automotive, mechanical, and industrial maintenance work performed by professional technicians and experienced tradespeople.

The J5017MH is used in situations requiring clearance over long bolt shanks, protruding studs, or deeply countersunk fastener heads. Common applications include suspension work, engine accessory removal, and general equipment maintenance where standard sockets lack the necessary reach. The 3/8 inch drive size positions this socket for medium-duty fastener work where torque requirements do not call for a larger drive. It is a hand-tool application and is not intended for impact driver use.

Key Features

• 17 mm socket size fits metric fasteners common in automotive and industrial equipment
• 6-point design maximizes contact area on fastener flats to reduce cam-out and rounding
• Deep length of 2.8 inches provides reach over studs, long bolts, and recessed fasteners
• 3/8 inch drive accepts standard ratchets, extensions, and breaker bars
• Chrome-plated finish resists corrosion and wipes clean in shop environments

Compatibility

Designed as an OEM-style hand socket compatible with standard 3/8 inch drive ratchets, extensions, and breaker bars in professional and service-shop tool setups.

Installation Notes

A licensed or experienced technician should verify fastener size and torque specifications before use. Always ensure the socket is fully seated on the fastener before applying torque to prevent slippage and fastener damage. Inspect the socket and drive square for wear or cracks before each use. This socket is rated for hand-tool use only and should not be used with pneumatic or electric impact drivers.
