Proto J54415/8XL 1/2 in Drive 5/8 in Hex Bit Socket Long

Product Description

The PROTO J54415/8XL is a long hex bit socket designed for professional hand-tool use in mechanical, HVAC, plumbing, and electrical trade applications. Built for a 1/2 inch drive, it accepts a 5/8 inch hex fastener and delivers extra reach with a 7-3/16 inch overall length and a 5-3/16 inch bit length. The extended length makes it well suited for deep fastener access in confined or recessed locations where a standard-length socket cannot reach. Licensed trades and service technicians who regularly work on equipment panels, flanged assemblies, or structural fasteners will find the added bit length reduces the need for extensions.

This hex bit socket is appropriate for residential and commercial service work across HVAC, plumbing, and general mechanical trades. It fits standard 1/2 inch square drive ratchets, breaker bars, and torque wrenches. The long configuration is especially useful when working around motor mounts, equipment frames, or pipe flanges where bolt heads are recessed well below the surface. It is a hand-tool application — not intended for impact driver use.

Key Features

• 1/2 inch square drive fits standard ratchets, breaker bars, and torque wrenches
• 5/8 inch hex bit size for common fastener sizes found in mechanical and trade equipment
• 7-3/16 inch overall length provides extended reach into recessed or deep fastener locations
• 5-3/16 inch bit length allows engagement with long hex fasteners and deep-set bolts
• Long hex bit socket configuration reduces reliance on add-on extensions in tight spaces

Compatibility

Designed for use with 1/2 inch square drive hand tools including ratchets, breaker bars, and torque wrenches. Fits 5/8 inch hex fasteners in standard hand-tool applications.

Installation Notes

Install and remove fasteners with the drive tool fully seated on the socket to prevent rounding. Confirm the hex bit is fully engaged with the fastener head before applying torque. This socket is rated for hand-tool use — do not use with impact drivers or pneumatic tools unless the tool and socket are both rated for impact service. Inspect the socket for cracks or wear before each use.
