Gibraltar 842635-G Steel T-slot Bolt 5/8-11 Black

Product Description

The GIBRALTAR 842635-G is a Grade 5 steel T-slot bolt designed for use in standard T-slot tracks and fixtures found in machining, fabrication, and industrial clamping applications. With a 5/8-11 UNC thread and a 2-inch thread length, it provides a secure mechanical connection in heavy-duty setups. The black finish offers a degree of corrosion resistance for shop and industrial environments. The low-profile T-slot head slides into the slot before being tightened, allowing fast fixture adjustments without disassembly. This bolt is a standard fastener choice for machinists, tool and die professionals, and industrial maintenance technicians working with slotted table systems.

This T-slot bolt fits into 5/8-inch wide T-slots, which are common on milling machine tables, welding fixtures, jig plates, and modular workholding systems. The 3-1/2-inch length under head accommodates moderate fixture stack heights. The 1-1/8-inch head width and 11/32-inch head height are dimensioned to seat properly in standard 5/8-inch slots without rocking or binding. It is suited for both production shop and toolroom use where repeatable clamping setups are required.

Key Features

• 5/8-11 UNC thread for compatibility with standard metric and fractional clamping hardware using matching nuts
• 2-inch thread length provides adequate engagement for most standard strap clamps and T-nuts
• 5/8-inch slot width fits standard T-slot tracks on milling tables and fixture plates
• Grade 5 steel construction rated for moderate to heavy clamping loads
• Black finish for basic surface protection in shop environments
• 3-1/2-inch length under head accommodates typical workholding stack heights

Compatibility

Designed for use in standard 5/8-inch T-slot tracks as found on milling machines, welding fixture tables, and industrial jig plates requiring 5/8-11 UNC threaded fasteners.

Installation Notes

Installation is performed by machinists or industrial maintenance technicians familiar with T-slot workholding systems. Slide the bolt head into the open end of the T-slot or drop it into an access point before positioning, then thread on the appropriate T-nut or strap clamp nut. Ensure the slot and bolt head surfaces are clean and free of chips before seating. Do not exceed the clamping load limits appropriate for Grade 5 hardware.
