Minerallac 55024J Hex Head Bolt 1/4-20 X 1-1/2 in Zinc Plated

Product Description

The MINERALLAC 55024J is a zinc-plated hex head bolt with a 1/4-20 thread size and 1-1/2-inch length. It is a general-purpose fastener used to secure conduit supports, electrical enclosures, equipment mounting brackets, and related hardware in mechanical and electrical installations. The zinc plating provides corrosion resistance suited to typical indoor and light commercial environments. Electricians, HVAC technicians, and plumbers commonly use this bolt when mounting strut channel fittings, hangers, and access panels.

This bolt is appropriate for light commercial and residential trade work where a 1/4-20 threaded fastener is specified. It fits standard 1/4-20 hex nuts and threaded inserts commonly found in unistrut and similar channel systems. The 1-1/2-inch length provides adequate thread engagement for most single-bracket and back-to-back mounting applications encountered in everyday trade service work.

Key Features

• 1/4-20 thread size for compatibility with standard nuts and threaded fittings
• 1-1/2-inch length suitable for single and stacked bracket installations
• Zinc plating for corrosion resistance in typical trade environments
• Hex head drive for use with standard wrenches and nut drivers

Compatibility

Designed as an OEM-style replacement or standard-stock fastener compatible with any application requiring a 1/4-20 x 1-1/2-inch zinc-plated hex head bolt.

Installation Notes

Install using a properly sized open-end wrench, box wrench, or nut driver rated for the fastener size. De-energize any electrical equipment before installing hardware in or near live panels or enclosures, in accordance with NEC lockout/tagout requirements. Do not overtighten, as this can strip threads in softer base materials such as aluminum strut or plastic mounting blocks. Verify thread engagement is sufficient for the load before placing the system in service.
