Gibraltar 841506-G Steel T-bolt 3/8-16 Grade 5

Product Description

The GIBRALTAR 841506-G is a Grade 5 steel T-bolt designed for secure fastening in applications that require a sliding, channel-mounted, or fixture-clamping connection. The T-bolt features a 3/8-16 UNC thread form with a 2-inch thread length and a 3-inch length under the head. The head measures 11/16 inches wide and 1/4 inch in height, allowing it to seat and lock into standard T-slot channels. Grade 5 alloy designation indicates medium-carbon steel with enhanced tensile strength compared to standard Grade 2 fasteners. Licensed trades and maintenance technicians use this type of hardware when assembling jigs, mounting rails, strut channel fixtures, or equipment enclosures.

T-bolts of this profile are commonly used in light industrial, HVAC mounting, and mechanical assembly environments. The 3/8-16 UNC thread is a widely standardized coarse-thread size that accepts matching hex nuts, flange nuts, and wing nuts. The 3-inch under-head length makes it suitable for moderate-depth T-slot tracks. This fastener is sold individually and is appropriate for both new installations and field replacements where a T-slot style bolt is required.

Key Features

• Grade 5 steel construction for higher tensile strength than standard Grade 2 fasteners
• 3/8-16 UNC coarse thread for broad compatibility with standard nuts and hardware
• 2-inch thread length provides ample engagement depth for secure clamping
• 11/16-inch head width sized to fit standard T-slot channel tracks
• 1/4-inch head height for low-profile seating in channel fixtures
• Steel construction suitable for dry and protected indoor mechanical environments

Compatibility

Designed as an OEM-style replacement or direct-use T-bolt for standard 3/8-16 UNC T-slot channel systems and fixture mounting applications.

Installation Notes

Installation is performed by tradespeople and maintenance technicians familiar with T-slot fastener systems. Before installation, ensure the mating channel or track is clean and free of debris that could prevent proper head seating. Torque the fastener to the specification recommended for the receiving structure and nut type used. Verify full thread engagement before applying final load to the joint.
