Proto J4716L Deep Hand Socket 1/2 in 6-point 1/4 in Drive

Product Description

The PROTO J4716L is a deep hand socket designed for professional hand-tool use in mechanical, industrial, and maintenance applications. Built on a 1/4 inch drive, this socket accepts 1/2 inch fasteners and features a 6-point internal geometry that maximizes contact with fastener flats, reducing rounding under torque. The chrome-plated finish provides corrosion resistance and makes the socket easy to clean after use. At 1.1 inches in length and weighing 0.13 pounds, it is compact enough for confined spaces while the deep configuration accommodates threaded studs and extended bolt shafts that a standard-depth socket cannot reach.

This socket is suited for automotive, fleet, and general mechanical work where 1/4 inch drive tooling is preferred for lighter fastener applications. The deep length makes it especially useful in engine bays, instrument panels, and equipment housings where fasteners sit recessed or are mounted on long studs. It is commonly used by automotive technicians, industrial maintenance mechanics, and skilled tradespeople who require precise torque application on 1/2 inch fasteners in tight or restricted access areas.

Key Features

• 6-point socket geometry maximizes flat contact with fastener surfaces to reduce slippage and rounding
• Deep length at 1.1 inches accommodates recessed fasteners and extended studs
• 1/4 inch drive fits standard quarter-drive ratchets, extensions, and torque tools
• Chrome-plated finish resists corrosion and simplifies cleanup
• Compact 0.7 inch width suitable for confined or restricted access locations
• Lightweight at 0.13 pounds for comfortable extended use

Compatibility

Designed as an OEM-style professional-grade deep hand socket compatible with standard 1/4 inch drive ratchets, extensions, and torque wrenches accepting 1/2 inch fasteners.

Installation Notes

Install and remove using a calibrated torque wrench or ratchet rated for 1/4 inch drive. Ensure the socket is fully seated on the fastener before applying torque to prevent rounding. Inspect the socket for cracks or deformation before each use and replace if any damage is found. Do not use impact drivers or air tools with hand sockets not rated for impact service.
