Gibraltar 841004-G Steel T-bolt 1/2-13 Unc Grade 5

Product Description

The GIBRALTAR 841004-G is a Grade 5 steel T-bolt designed for secure fastening applications that require a sliding or track-mounted connection. The T-profile head fits into slotted channels or fixture tracks, allowing repositioning before final torque. It carries a 1/2-13 UNC thread and measures 2 inches in length under the head, with 1.75 inches of usable thread length. A black oxide finish provides moderate corrosion resistance in dry or lightly controlled environments. HVAC, electrical, and mechanical contractors commonly use T-bolts like this one for equipment mounting, strut-channel assemblies, and framing connections where a standard hex head cannot be inserted from above.

This T-bolt is suited for light industrial and commercial mechanical applications. Its 1/2-13 UNC thread pattern is compatible with standard UNC nuts and hardware. The black oxide finish makes it appropriate for interior installations where appearance and mild corrosion protection both matter. A head width of 0.875 inches and head height of 0.3125 inches are sized to fit common slotted-channel and T-track profiles used in mechanical and HVAC system framing.

Key Features

• 1/2-13 UNC thread for compatibility with standard nuts and hardware
• Grade 5 steel construction for reliable tensile and shear strength
• Black oxide finish for moderate corrosion resistance in interior environments
• T-profile head slides into slotted channel tracks for adjustable positioning
• 1.75 inches of thread length provides adequate engagement depth for secure fastening

Compatibility

Designed as an OEM-style replacement or direct-use fastener for slotted-channel and T-track framing assemblies in mechanical, HVAC, and light industrial installations.

Installation Notes

Installation is performed by licensed mechanical contractors or qualified tradespeople working with channel-frame systems. De-energize or de-pressurize any system section before tightening fasteners into live assemblies. Use a calibrated torque wrench appropriate for Grade 5 fasteners at 1/2-13 UNC thread engagement. Follow applicable mechanical and structural codes for the jurisdiction when specifying fastener grade and quantity for load-bearing connections.
