Minerallac 55426J Hex Tap Bolt 3/8-16 X 1-1/2

Product Description

The MINERALLAC 55426J is a 3/8-16 x 1-1/2 inch hex tap bolt used to fasten components in electrical, mechanical, and structural assembly applications. It features a unified coarse (UNC) thread profile at 3/8-16 and a hex head for standard wrench or socket drive installation. At 1-1/2 inches in length, it is suited for medium-depth fastening tasks common in panel mounting, conduit support, and equipment attachment. Electricians, HVAC technicians, and general trade contractors regularly stock this fastener for routine field and shop work.

This hex tap bolt is appropriate for use in both residential and light commercial applications where a fully threaded, hex-drive fastener is required. Typical scenarios include securing electrical enclosures, mounting brackets, strut channel end caps, and similar hardware assemblies. The 3/8-16 UNC thread size is a widely used standard that fits corresponding tapped holes and hex nuts across a broad range of trade hardware.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard tapped hardware
• 1-1/2 inch length suitable for medium-depth fastening in panels and enclosures
• Hex head drive accepts standard wrenches and sockets for secure installation
• Fully threaded shank provides consistent thread engagement along the full length

Compatibility

Designed as a standard 3/8-16 x 1-1/2 inch hex tap bolt for use wherever a UNC hex fastener of this size is specified in electrical, HVAC, or general mechanical assembly applications.

Installation Notes

Installation is performed by electricians, HVAC technicians, or mechanical contractors using a standard wrench or socket set. Ensure the receiving hole is correctly tapped to 3/8-16 UNC before installation to avoid cross-threading. De-energize any electrical equipment and follow applicable NEC lockout/tagout procedures before fastening hardware inside live enclosures. Do not overtighten, as excessive torque can strip the tapped threads in softer base materials.
