Gibraltar 841107-G Steel T-bolt 5/8-11 Grade 5

Product Description

The GIBRALTAR 841107-G is a Grade 5 steel T-bolt designed for secure fastening in applications that require a sliding or channel-mount connection. It features a 5/8-11 UNC thread with a 2-inch thread length and a 3.5-inch length under the head. The T-shaped head measures 1.125 inches wide and 0.406 inches tall, allowing it to seat into standard T-slot tracks and channel assemblies. Constructed from Grade 5 steel, this bolt provides the tensile strength and shear resistance required in structural and mechanical clamping setups. HVAC, mechanical, and industrial technicians commonly install this hardware in framing, equipment mounting, and duct-support configurations.

This T-bolt is suited for use in T-slot framing systems, aluminum extrusion channels, and slotted steel tracks commonly found in equipment mounting, panel framing, and mechanical support structures. The 5/8-11 UNC thread pattern is a widely used coarse-thread standard, compatible with standard hex nuts and flange nuts of matching thread designation. It is appropriate for both light commercial and industrial applications where a bolt must be inserted into a channel and rotated to lock in place before tightening.

Key Features

• 5/8-11 UNC coarse thread for broad nut and hardware compatibility
• 2-inch thread length provides adequate engagement for standard fastening depth
• 3.5-inch length under head accommodates thicker channel walls and stacked materials
• Head width of 1.125 inches and head height of 0.406 inches sized for T-slot channel seating
• Grade 5 steel construction meets medium-strength fastener requirements
• Sold individually, allowing single-unit replacement or small-quantity procurement

Compatibility

Designed as a standard replacement or new-installation T-bolt for T-slot channel framing systems and slotted mounting tracks using 5/8-11 UNC threaded hardware.

Installation Notes

Installation should be performed by a qualified mechanical or trade technician following applicable structural fastening guidelines. Before installation, confirm the channel slot width is compatible with the 1.125-inch head width to ensure proper seating and rotation. Torque the mating nut to values appropriate for Grade 5 5/8-inch fasteners as specified by the equipment manufacturer or applicable mechanical codes. Do not over-tighten in aluminum extrusion channels, as this may deform the channel walls.
