Proto J49903/8XL Hand Hex Bit Socket 3/8 in Drive 3/8 in Hex

Product Description

The PROTO J49903/8XL is a long hand hex bit socket designed for manual drive applications requiring extended reach and precise hex fastener engagement. Built around a 3/8 inch drive, this socket accepts a 3/8 inch hex bit and delivers a 5 inch bit length with an overall length of 6-3/32 inches. The extended OAL makes it well suited for deep fastener access in confined or recessed locations. Electricians, HVAC technicians, plumbers, and general trade professionals reach for long hex bit sockets when standard-length tools cannot seat fully on a recessed fastener or when working through access panels and tight enclosures.

This socket is appropriate for residential and light commercial service work where 3/8 inch drive hand tools are standard. Typical applications include equipment assembly, panel fasteners, motor mounts, and any hex-drive fastener that requires additional bit depth to fully engage. The long configuration is particularly useful when working in equipment cabinets, electrical enclosures, or mechanical rooms where fastener heads sit below a surface or behind a shroud.

Key Features

• 3/8 inch drive fits standard 3/8 inch drive ratchets, breaker bars, and extensions
• 3/8 inch hex bit size for matching hex-drive fasteners
• 5 inch bit length provides extended reach into deep or recessed fastener locations
• 6-3/32 inch overall length for clearance in confined work areas
• Long hex bit socket configuration reduces the need for add-on extensions

Compatibility

Designed as a standard 3/8 inch drive hex bit socket compatible with any 3/8 inch drive ratchet, torque wrench, or extension bar conforming to standard square drive tooling dimensions.

Installation Notes

Used by licensed tradespeople and professional technicians working on hex-drive fasteners in HVAC, electrical, and mechanical applications. Ensure the socket is fully seated on the drive tool and the bit is fully engaged with the fastener before applying torque to avoid rounding fastener heads or damaging the bit. Inspect the socket and bit for wear or cracking before use, and replace if any deformation is observed.
