Value Collection 474017PS Step Bolt 1/4-20 2.5 in Zinc Steel

Product Description

The VALUE COLLECTION 474017PS is a 1/4-20 UNC step bolt designed for structural and mechanical fastening applications where a larger bearing surface under the head is required. The bolt measures 2.5 inches in length under the head and features a 27/32-inch head diameter, conforming to ANSI/ASME B18.5 standards. It is manufactured from 1006/1050 steel with a zinc-plated finish for basic corrosion resistance. This fastener is installed by contractors, millwrights, ironworkers, and maintenance technicians in a wide range of light structural and mechanical assembly scenarios.

Step bolts are commonly used in industrial, construction, and utility applications where climbing, grating, or step attachment points are required. The larger head diameter distributes load across a wider surface area, making this bolt well-suited for connecting ladder rungs, grating panels, and similar structural components. The 1/4-20 UNC thread is a standard coarse-thread configuration compatible with standard nuts and tapped components in inch-system assemblies.

Key Features

• 1/4-20 UNC coarse-thread configuration for compatibility with standard inch-system hardware
• 2.5-inch length under head suits moderate-depth structural connections
• 27/32-inch head diameter (0.813 to 0.844 inches) provides a wide bearing surface for step and grating applications
• Zinc-plated finish offers basic corrosion protection in dry to mildly humid environments
• Manufactured to ANSI/ASME B18.5 dimensional standards for consistent fitment
• 1006/1050 steel construction provides adequate strength for standard structural fastening loads

Compatibility

Designed as an OEM-style replacement or direct-use fastener for inch-system structural assemblies requiring a 1/4-20 UNC step bolt conforming to ANSI/ASME B18.5 specifications.

Installation Notes

Installation is performed by qualified tradespeople using standard hand or power tools appropriate for 1/4-20 fasteners. Always ensure mating threads are clean and free of debris before installation. Apply thread engagement of at least 1.5 times the bolt diameter for structural connections unless specifications dictate otherwise. Follow applicable building codes and structural standards when using step bolts in load-bearing or climbing-surface applications.
