Gibraltar 841512-G Steel T-bolt 3/8-16 Grade 5

Product Description

The GIBRALTAR 841512-G is a Grade 5 steel T-bolt designed for secure fastening in structural and mechanical assemblies. It features a 3/8-16 UNC thread standard with a 2-inch thread length and a 6-inch length under the head, making it suitable for applications that require extended reach through thick materials or channel track systems. The T-shaped head measures 11/16 inches wide and 1/4 inch tall, allowing it to seat and lock into slotted channel framing without rotation. Licensed tradespeople working with unistrut-style channel or similar slotted framing systems will find this bolt meets standard Grade 5 mechanical strength requirements for general industrial and construction use.

This T-bolt is commonly used in channel framing installations, equipment mounting, solar panel racking, electrical enclosure mounting, and structural support systems. Its 3/8-16 UNC thread is a widely used standard pitch, compatible with matching nuts and washers used across residential and commercial mechanical and electrical installations. The 6-inch length under the head provides enough clearance for thick brackets, multiple stacked materials, or gusseted mounting points.

Key Features

• Grade 5 steel construction for reliable tensile and shear strength in mechanical assemblies
• 3/8-16 UNC thread standard ensures broad compatibility with standard hardware
• T-shaped head locks into slotted channel framing to prevent rotation during tightening
• 2-inch thread length provides adequate engagement for full-strength fastening
• 6-inch length under head accommodates thick material stacks and deep channel profiles

Compatibility

Designed as a standard replacement or new-installation T-bolt for use with 3/8-16 UNC slotted channel framing systems and compatible T-bolt nuts in mechanical, electrical, and structural applications.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with mechanical fastening and applicable structural or electrical codes. Power down or de-energize any adjacent equipment before working in enclosures or panel mounting areas. Insert the T-bolt head into the channel slot, rotate 90 degrees to lock in place, then tighten with an appropriate wrench to the torque specification required by the channel manufacturer. Do not over-torque, as this may deform the channel slot or compromise clamping integrity.
