Value Collection 474008PS Step Bolt 1/4-20 Zinc Steel

Product Description

The VALUE COLLECTION 474008PS is a 1/4-20 UNC step bolt designed for structural and mechanical fastening applications where a broad bearing surface under the head is required. The bolt measures 1 inch in length under the head with a head diameter ranging from 0.813 to 0.844 inches. Manufactured from 1006-1050 steel and finished with a zinc plating for corrosion resistance, this fastener conforms to ANSI/ASME B18.5 standards. It is suited for contractors, maintenance technicians, and tradespeople working with inch-series fasteners in light to medium-duty assemblies.

Step bolts in this size range are commonly used in general construction, equipment mounting, and structural steel connections where a round, flat head profile is needed to distribute load across a wider surface area. This bolt is appropriate for residential and light commercial applications involving wood, metal, or composite substrates. Each unit is sold individually, with a minimum order quantity of 50 pieces per order.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard inch-series nuts and tapped holes
• 1 inch length under head for precise fit in shallow-to-mid-depth fastening applications
• Head diameter of 0.813 to 0.844 inches provides a wide bearing surface to reduce pull-through
• 1006-1050 steel construction offers reliable tensile strength for general-duty use
• Zinc-plated finish provides baseline corrosion protection in dry to mildly humid environments
• Meets ANSI/ASME B18.5 fastener standard for dimensional consistency

Compatibility

Designed as an OEM-style replacement or standard-service step bolt for use with 1/4-20 UNC inch-series hardware in general mechanical and construction fastening applications.

Installation Notes

Step bolts are installed by general contractors, maintenance mechanics, and tradespeople using standard hand or power tools compatible with the head drive type. Always verify thread engagement depth and substrate thickness before installation to ensure full thread capture. Torque to the assembly specification appropriate for the joint material and application. Do not overtighten, as zinc plating on light-gauge steel fasteners can be damaged by excessive torque.
