Gibraltar 841106-G Steel T-bolt 5/8-11 2in Thread Grade 5

Product Description

The GIBRALTAR 841106-G is a Grade 5 steel T-bolt designed for secure fastening applications in mechanical, HVAC, and industrial assembly work. It features a 5/8-11 UNC thread with a 2-inch thread length and a 3-inch length under the head. The head measures 1-1/8 inches wide by 13/32 inches tall, providing a broad bearing surface suited for channel and strut mounting. A black oxide finish offers basic corrosion resistance in dry or sheltered environments. This fastener is installed by mechanical and HVAC tradespeople where a T-slot or channel-track fastening system is required.

This T-bolt is commonly used in strut channel systems, equipment mounting rails, and structural support assemblies in commercial and residential HVAC, plumbing support, and general mechanical installations. The 5/8-11 UNC thread size makes it compatible with standard heavy-duty strut hardware and channel nuts. It is appropriate for indoor and sheltered outdoor use where a black oxide finish provides adequate surface protection.

Key Features

• 5/8-11 UNC thread for compatibility with standard heavy-duty strut and channel hardware
• 2-inch thread length provides ample engagement for secure fastening
• 3-inch length under head accommodates typical strut channel depths
• Grade 5 steel construction for reliable tensile and shear strength
• Black oxide finish for basic surface protection in dry environments
• 1-1/8-inch head width delivers broad bearing contact in T-slot applications

Compatibility

Designed as a standard-fitment T-bolt for use with 5/8-11 UNC channel nuts and strut hardware in mechanical support and equipment mounting applications.

Installation Notes

This fastener is installed by HVAC, plumbing, and mechanical tradespeople working with strut channel support systems. De-energize and depressurize any systems in the work area before installing or adjusting support hardware. Use a calibrated torque wrench appropriate for Grade 5 fasteners and follow the fastener manufacturer or system manufacturer torque guidelines. Refer to applicable building and mechanical codes for support spacing and load requirements.
