Proto J47709/64B 1/4 in Drive 9/64 in Hex Bit Socket

Product Description

The PROTO J47709/64B is a ball end hex bit socket designed for hand tool use with a 1/4 inch drive. It accepts a 9/64 inch hex fastener and features a ball end geometry that allows engagement at off-axis angles, making it useful when direct inline access to a fastener is restricted. The overall length is 1.5 inches, with a bit length of 1.047 inches. This type of socket is commonly used by HVAC technicians, electricians, plumbers, and general mechanical trades when working with equipment panels, access covers, and machine screws that require hex drive input.

This hex bit socket suits both residential and light commercial service work. It is a practical addition to a drive socket set when working inside tight equipment cabinets, electrical enclosures, or mechanical assemblies where hex head fasteners are used. The ball end design allows the socket to engage fasteners at an angle when a straight-on approach is not possible, reducing the need to reposition the tool between each fastener. This makes it a time-saving option during panel removal and reassembly tasks common in field service work.

Key Features

• Ball end design allows off-axis fastener engagement for use in confined spaces
• 1/4 inch drive for use with standard hand ratchets and drive extensions
• 9/64 inch hex size for metric and fractional hex fasteners common in equipment assemblies
• Compact 1.5 inch overall length suitable for shallow access areas
• 1.047 inch bit length provides adequate engagement depth on standard hex fasteners

Compatibility

Designed as an OEM-style hand tool socket for use with 1/4 inch drive ratchets, extensions, and drive handles.

Installation Notes

This socket is installed and used by any trade professional working with 1/4 inch drive hand tools. Ensure the drive tool and socket are fully seated before applying torque to avoid rounding fastener heads. The ball end geometry is best suited for initial engagement and final tightening at mild angles; avoid applying heavy torque at extreme off-axis angles to preserve socket and fastener integrity. No power shutoff is required for the tool itself, but always follow site safety procedures when working inside energized equipment enclosures.
