Gibraltar 841005-G T-bolt 1/2-13 Unc Steel Grade 5

Product Description

The GIBRALTAR 841005-G is a Grade 5 steel T-bolt with a 1/2-13 UNC thread profile, designed for secure fastening in applications that require a sliding or channel-mount connection. It features a 2-inch thread length and a 2.5-inch length under the head, making it suitable for medium-depth clamping assemblies. The black oxide finish provides moderate corrosion resistance and reduces light reflection in industrial environments. This hardware is commonly installed by millwrights, HVAC technicians, electricians, and plumbers wherever T-slot framing, strut channel, or fixture rails are used.

This T-bolt is intended for use in T-slot tracks, channel framing systems, and similar sliding-fastener assemblies found in both commercial and light industrial installations. The 7/8-inch head width and 5/16-inch head height are sized to fit standard T-slot profiles, allowing the bolt to be inserted and rotated into a locked position within the channel. It is a single-piece fastener sold individually and is well suited for equipment mounting, support brackets, and fixture assembly tasks.

Key Features

• 1/2-13 UNC thread for wide compatibility with standard nuts and hardware
• 2-inch thread length provides sufficient engagement depth for secure clamping
• Grade 5 steel construction delivers reliable tensile strength for medium-load applications
• Black oxide finish offers mild corrosion resistance and a low-reflectance surface
• 7/8-inch head width fits standard T-slot channel profiles
• 5/16-inch head height allows clean seating within the channel groove

Compatibility

Designed as an OEM-style replacement or direct installation fastener for T-slot channel framing and strut systems using 1/2-13 UNC hardware.

Installation Notes

Installation is typically performed by a licensed tradesperson or qualified maintenance technician. Disengage all power and relieve any load from the assembly before servicing or replacing fasteners. Use appropriately rated wrenches or sockets for the 1/2-inch thread size and ensure the T-bolt head is fully seated and rotated to the locked position within the channel before applying torque to the mating nut. Follow applicable mechanical codes for fastener selection and load ratings in structural or equipment-support applications.
