Gibraltar 842550-G Steel T-slot Bolt 1/2-13 Black

Product Description

The GIBRALTAR 842550-G is a Grade 5 steel T-slot bolt designed for secure fastening in T-slotted framing, fixtures, and machine tables. With a 1/2-13 UNC thread and a 2.5-inch thread length, it delivers reliable clamping force in standard half-inch T-slots. The black finish provides a degree of corrosion resistance for shop and industrial environments. The 5-inch length under head and 7/8-inch head width give the bolt a stable seating profile in most standard T-slot channel configurations. This fastener is typically installed by machinists, millwrights, and fabricators working with modular fixturing systems.

This T-slot bolt is suited for use in manufacturing fixtures, welding tables, CNC machine beds, and modular workholding systems that use half-inch T-slots. It is appropriate for both light industrial and heavy-duty fixturing applications where Grade 5 tensile strength is required. The sold-as-single packaging makes it practical for replacement of individual fasteners or small-run builds.

Key Features

• 1/2-13 UNC thread standard for broad hardware compatibility
• 2.5-inch thread length provides ample engagement depth for most clamping setups
• Half-inch slot width fits standard T-slot channel profiles
• Grade 5 steel construction for reliable tensile and shear strength
• Black finish for corrosion resistance in shop environments
• 5-inch length under head accommodates thicker workpieces and clamp stacks

Compatibility

Designed as a standard replacement or build fastener for T-slotted tables, fixtures, and framing systems that accept 1/2-inch T-slot bolts with 1/2-13 UNC threading.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using standard hand tools. Ensure the T-slot channel is free of debris before inserting the bolt head. Torque to values appropriate for Grade 5 hardware per the applicable fixturing or equipment specification. Do not exceed the rated torque for the clamping hardware being used.
