Value Collection R52001064 Step Bolt 1/4-20 Zinc

Product Description

The VALUE COLLECTION R52001064 is a step bolt designed for use in structural and mechanical fastening applications where a broad bearing head is required. Manufactured from 1006/1050 steel with a zinc-plated finish for basic corrosion resistance, this bolt features a 1/4-20 UNC thread and a length under head of 1.75 inches. The head diameter ranges from 0.813 to 0.844 inches (27/32 inches nominal), providing the wide, low-profile bearing surface characteristic of step bolts. Licensed tradespeople and fabricators working in construction, HVAC support structure, and mechanical systems commonly install this fastener type.

This step bolt is suited for residential and light commercial applications requiring ANSI/ASME B18.5 compliant fasteners. The 1/4-20 UNC thread is one of the most common inch-series thread sizes, making this bolt applicable across a wide range of structural attachment, framing, and bracket-mounting scenarios. It is sold individually but must be ordered in multiples of 50 units to meet the minimum order quantity requirement.

Key Features

• 1/4-20 UNC thread form per ANSI/ASME B18.5 standard
• 1.75 inches length under head for consistent grip length measurement
• 27/32 inches nominal head diameter (0.813 to 0.844 inches) provides wide bearing surface
• 1006/1050 steel construction for reliable tensile strength in general fastening applications
• Zinc-plated finish offers basic corrosion protection in dry to mildly humid environments
• Minimum order quantity of 50 units suits bulk trade procurement

Compatibility

Designed as a general-purpose inch-series step bolt conforming to ANSI/ASME B18.5, suitable for use wherever a 1/4-20 UNC step bolt with a 1.75-inch length under head is specified.

Installation Notes

Step bolts of this type are installed by carpenters, ironworkers, HVAC technicians, and general tradespeople using standard hand tools or impact drivers rated for 1/4-20 fasteners. Always ensure the mating nut or tapped hole thread standard matches UNC before installation. Follow applicable ANSI and project specification torque guidance for 1/4-20 fasteners in the relevant material. Inspect zinc-plated fasteners before use in environments with prolonged moisture exposure, as the coating is not rated for heavy corrosive conditions.
