Proto J4770-6M Hand Hex Bit Socket 1/4 in Drive 6 Mm

Product Description

The PROTO J4770-6M is a hand hex bit socket designed for manual drive applications requiring precise hex fastener engagement. Built for 1/4 inch drive tools, this socket accepts a 6 mm hex bit and delivers a 1 inch bit length for solid fastener contact. The overall length measures 1-7/8 inches, keeping the profile compact for work in tighter spaces. It is a standard addition to the toolbox of electricians, HVAC technicians, plumbers, and mechanical contractors who regularly encounter hex-head fasteners during equipment installation and service.

This hex bit socket fits standard 1/4 inch drive ratchets and drive handles, making it suitable for residential and light commercial service work. The 6 mm hex size is common on equipment panels, junction box hardware, machine screws, and fasteners found throughout HVAC units, electrical enclosures, and plumbing fixtures. The compact 1-7/8 inch overall length allows use in moderate access constraints without sacrificing torque transfer through the drive interface.

Installation Notes

This socket is installed by hand tool technicians and trade professionals working on mechanical, electrical, or HVAC equipment. Ensure the drive connection is fully seated before applying torque to avoid rounding the fastener or damaging the socket. De-energize electrical equipment and shut off any relevant systems before accessing fasteners on panels or enclosures. Follow applicable codes and manufacturer torque guidance for the equipment being serviced.
