Gibraltar 841007-G T-bolt 1/2-13 Grade 5 Steel Black Oxide

Product Description

The GIBRALTAR 841007-G is a Grade 5 steel T-bolt designed for secure fastening applications where a standard hex bolt cannot rotate freely into position. The T-shaped head slides into a mating channel or slot, then locks in place when torqued, making it a standard choice for machine tables, fixtures, framing channels, and structural connections. The bolt features a 1/2-13 UNC thread form with a 2-inch thread length and a 3-1/2-inch length under head. A black oxide finish provides moderate corrosion resistance for indoor and light-duty industrial environments. Licensed tradespeople and equipment technicians install this hardware in fabrication shops, HVAC equipment mounting, and similar mechanical assembly work.

This T-bolt is suited for use in T-slot tables, strut channel systems, and equipment mounting frames where a captured head fastener is required. The 7/8-inch head width and 5/16-inch head height are sized to fit standard T-slot profiles used in light to medium industrial assemblies. The 1/2-13 UNC coarse thread engages standard hex nuts and flanged nuts commonly stocked for structural and mechanical work.

Key Features

• Grade 5 steel construction for reliable tensile and shear strength in structural fastening
• 1/2-13 UNC coarse thread for broad compatibility with standard nuts and hardware
• 2-inch thread length provides adequate engagement for typical fastening depths
• 3-1/2-inch length under head accommodates standard T-slot channel and fixture thicknesses
• Black oxide finish offers moderate corrosion resistance for dry and indoor environments
• T-head profile seats into T-slot channels and locks when tightened

Compatibility

Designed for use in standard T-slot channels and strut channel framing systems requiring a 1/2-13 UNC captured-head bolt. Verify T-slot width and depth dimensions against the 7/8-inch head width and 5/16-inch head height before installation.

Installation Notes

Install this T-bolt by sliding the head into the T-slot channel before assembling the joint, as the head cannot be inserted after surrounding components are in place. Use standard hand tools and a torque wrench sized for 1/2-inch fasteners. Follow applicable mechanical or structural codes for the fastener grade and torque class required by the assembly. Always de-energize and lock out any powered equipment before working on mounting hardware secured to machinery.
