Proto J4990R-6M Hex Bit Socket 6mm 2.75 Inches

Product Description

The PROTO J4990R-6M is a hex bit socket designed for hand tool use in professional trade and industrial settings. Built from steel with a chrome finish, this socket accepts a 6 mm hex bit and measures 2.75 inches in overall length. It is a non-insulated, non-sparking drive tool intended for use with standard ratchets and extensions. HVAC technicians, plumbers, electricians, and general mechanical trades rely on hex bit sockets for fastener engagement in tight or deep-access locations where a standard wrench cannot reach. The chrome finish provides corrosion resistance during regular shop or field use.

This socket is suited for residential and commercial service work where 6 mm hex fasteners are common, including equipment panels, junction boxes, pipe fittings, and mechanical assemblies. The 2.75-inch bit length provides additional reach for recessed fasteners without requiring an extension in many applications. Sold individually, it fits into standard hex bit socket sets or serves as a standalone replacement when a specific size is needed.

Key Features

• 6 mm hex bit size for precise fastener engagement
• 2.75-inch overall length for added reach in recessed applications
• Steel construction with chrome finish for durability and corrosion resistance
• Non-insulated design for standard mechanical use
• Sold as a single unit, compatible with standard ratchet drives

Compatibility

Designed as an OEM-style replacement or addition for standard hex bit socket sets requiring a 6 mm bit socket.

Installation Notes

This socket is intended for use by qualified trade professionals working with hand ratchets or extensions. Confirm the drive size of your ratchet matches the socket drive before use. Do not use this non-insulated socket on live electrical components. Inspect the socket for wear or cracking before each use and replace if damage is observed.
