Proto J4705M 5mm 6-point 1/4 Drive Hand Socket Chrome

Product Description

The PROTO J4705M is a 5 mm, 6-point hand socket designed for use with a 1/4 inch drive ratchet or extension. The 6-point geometry provides full contact on fastener flats, reducing the risk of rounding under torque. A chrome-plated finish resists corrosion and makes the socket easy to clean after use. At standard length, this socket fits most bench-level and under-hood fastener work where a deep socket is not required. It is suited for professional mechanics, maintenance technicians, and industrial service personnel who work with metric fasteners.

This socket is used in general mechanical assembly, equipment maintenance, and vehicle service applications where 5 mm metric fasteners are encountered. Standard-length sockets of this size are common in automotive engine accessory work, light equipment repair, and precision assembly tasks. The 1/4 inch drive size is appropriate for lower-torque applications and tight-clearance work where a compact drive is preferred over a larger 3/8 or 1/2 inch drive setup.

Key Features

• 5 mm socket size fits standard metric fasteners
• 6-point design maximizes contact area on fastener flats to reduce rounding
• 1/4 inch drive compatible with standard ratchets, extensions, and torque wrenches
• Chrome-plated finish provides corrosion resistance and easy cleaning
• Standard length profile suits most open-access fastener locations
• Lightweight at 0.02 pounds for reduced hand fatigue during repetitive use

Compatibility

Designed as an OEM-style replacement or addition to any standard 1/4 inch drive socket set. Compatible with 1/4 inch drive ratchets, extensions, and torque wrenches following standard drive coupling dimensions.

Installation Notes

This socket is installed and removed by hand onto a 1/4 inch drive tool — no special tools are required for setup. Ensure the drive detent fully engages the socket before applying torque to prevent slippage. Do not use impact drivers with this hand socket, as it is not rated for impact use. Inspect the socket for cracks or wear before each use and replace if the chrome finish shows significant flaking or the drive square shows deformation.
