Minerallac 55440J Hex Head Bolt 3/8-16 X 2.5 in

Product Description

The MINERALLAC 55440J is a 3/8-16 x 2.5-inch hex head bolt designed for secure mechanical fastening in electrical, HVAC, and general trade applications. The 3/8-16 thread designation indicates a 3/8-inch nominal diameter with 16 threads per inch (UNC coarse thread), making it compatible with standard 3/8-16 nuts and tapped holes. At 0.09 pounds, this is a lightweight yet robust fastener suited for panel mounting, equipment anchoring, and structural connections common in trade installations.

This hex head bolt is commonly used by electricians, HVAC technicians, and plumbers for equipment mounting, conduit support hardware, and general mechanical assembly. Its coarse thread pattern allows for faster installation and better resistance to cross-threading in field conditions. The hex head drive accommodates standard 9/16-inch wrenches and sockets, which are standard in every trade kit.

Key Features

• 3/8-16 UNC coarse thread for broad hardware compatibility
• 2.5-inch length suitable for through-bolting standard brackets and enclosures
• Hex head drive compatible with 9/16-inch wrenches and sockets
• Lightweight at 0.09 pounds for easy handling in overhead or confined installations

Compatibility

Designed as a standard 3/8-16 UNC hex head fastener for use with any 3/8-16 threaded nut, insert, or tapped fitting in electrical, HVAC, plumbing, or general mechanical applications.

Installation Notes

Install using a 9/16-inch wrench or socket driver. Power down or de-energize any equipment before fastening hardware to electrical enclosures or panels. Follow applicable NEC or local mechanical code requirements for equipment mounting torque and fastener spacing. Do not overtighten in thin-gauge sheet metal applications to avoid stripping threads.
