Minerallac 55422J Hex Tap Bolt 3/8-16 X 1-1/4

Product Description

The MINERALLAC 55422J is a hex tap bolt with a 3/8-16 thread and a 1-1/4 inch length. Hex tap bolts are fully threaded fasteners used to secure electrical enclosures, conduit supports, mounting brackets, and structural hardware in commercial and residential applications. The hex head accepts standard wrenches and sockets for straightforward installation. Electricians, HVAC technicians, and general trade contractors reach for this fastener when a reliable, fully threaded hex bolt is needed for a clean, secure connection.

This bolt is suited for a wide range of trade installations where a 3/8-16 coarse-thread fastener is specified. Common applications include securing junction boxes, panel enclosures, equipment mounting feet, and conduit strut hardware. The coarse 3/8-16 thread pitch provides strong engagement in standard tapped holes and pairs well with 3/8-16 nuts and threaded inserts commonly found in electrical and mechanical assemblies.

Key Features

• 3/8-16 coarse thread for broad compatibility with standard tapped hardware
• 1-1/4 inch length suits typical panel and enclosure mounting depths
• Hex head design accepts standard wrenches and socket drives
• Fully threaded shank maximizes thread engagement across the full bolt length

Compatibility

Designed as an OEM-style replacement or standard fastener for electrical enclosures, conduit supports, and mechanical mounting applications requiring a 3/8-16 x 1-1/4 inch hex tap bolt.

Installation Notes

Installation is typically performed by licensed electricians or HVAC technicians as part of enclosure or equipment mounting work. De-energize all circuits and follow applicable NEC guidelines before working inside electrical enclosures. Use a properly sized wrench or socket to torque the bolt against the mating hardware without over-driving. Inspect the mating tapped hole or nut for thread condition before installation to ensure full engagement.
