Value Collection 474012PS Step Bolt 1/4-20 1-1/2 in

Product Description

The VALUE COLLECTION 474012PS is a 1/4-20 step bolt designed for structural and mechanical fastening applications where a larger bearing surface under the head is required. Manufactured from 1006/1050 steel with a zinc-plated finish for basic corrosion resistance, this bolt measures 1-1/2 inches in length under the head and carries a 27/32-inch head diameter. It conforms to ANSI/ASME B18.5 standards, ensuring dimensional consistency for trade and industrial use. Licensed tradespeople working in equipment assembly, structural mounting, or mechanical installations will find this bolt suited for standard inch-system fastening tasks.

This step bolt is intended for use in general mechanical, structural, and industrial applications where UNC thread engagement and a large-diameter round head are specified. The 1/4-20 UNC thread is one of the most common inch-series thread sizes, making this fastener compatible with a wide range of standard tapped holes, nuts, and threaded inserts. Typical install scenarios include equipment framing, bracket attachment, and panel mounting where the broad head distributes load across the mating surface.

Key Features

• 1/4-20 UNC thread for compatibility with standard inch-series tapped components
• 1-1/2 inch length under head for consistent grip length in standard clearance holes
• 27/32-inch head diameter (0.8130 to 0.8440 inches) provides a wide load-bearing surface
• 1006/1050 steel construction for reliable tensile strength in light to moderate fastening applications
• Zinc-plated finish offers basic corrosion and oxidation resistance for indoor and sheltered environments
• Conforms to ANSI/ASME B18.5 fastener standard for dimensional accuracy

Compatibility

Designed as an OEM-style replacement or standard-service fastener for applications specifying a 1/4-20 UNC step bolt per ANSI/ASME B18.5 in inch-measurement systems.

Installation Notes

Installation is performed by qualified mechanics, millwrights, or trade technicians using standard hand or power tools appropriate for 1/4-20 fasteners. Always verify thread engagement depth and hole clearance before driving. Do not exceed the load rating of the mating material. Follow applicable ASME or facility-specific fastener torque guidelines when specified by the equipment manufacturer.
