Value Collection C80529 Step Bolt 1/4-20 2 Inch Zinc-plated

Product Description

The VALUE COLLECTION C80529 is a 1/4-20 UNC step bolt made from steel with a zinc-plated finish. Step bolts are carriage-style fasteners with an enlarged, low-profile dome head and a smooth shank section below the head, designed to resist pull-through in wood, grating, and structural applications. This bolt measures 2 inches in length under the head with a head diameter between 0.813 and 0.844 inches. Material grade ranges from 1006 to 1050 steel, providing moderate tensile strength suitable for general structural and utility fastening tasks. Sold in a package of 25. Installers working in mechanical, electrical, or structural trades use this bolt where a wide bearing head and flush-seating profile are required.

Step bolts are commonly used in utility and construction applications such as securing wood or composite treads to metal stringers, attaching grating panels, and fastening structural members where a low-profile head is needed. They are appropriate for both indoor and outdoor installations when used with the zinc-plated finish, which provides a baseline level of corrosion resistance in dry to mildly exposed environments. These conform to ANSI/ASME B18.5 dimensional standards, making them drop-in compatible with standard UNC hardware assemblies.

Key Features

• 1/4-20 UNC thread with 2-inch length measured under the head
• Enlarged dome head at 0.813 to 0.844 inches in diameter for increased bearing surface
• Steel construction, material grade 1006-1050, for general-duty structural fastening
• Zinc-plated finish for basic corrosion resistance in dry and mildly exposed conditions
• Meets ANSI/ASME B18.5 fastener standard for dimensional consistency
• Packaged in a quantity of 25 per unit

Compatibility

Designed as a general-purpose UNC step bolt conforming to ANSI/ASME B18.5, suitable for use in standard 1/4-20 threaded applications requiring a wide-bearing dome head profile.

Installation Notes

Step bolts are typically installed by carpenters, ironworkers, electricians, or general maintenance trades. Power down or de-energize any adjacent equipment before working in panel or grating installations. Use a correctly sized wrench or socket on the nut side only, as the smooth dome head is not intended to be driven with a tool. Follow applicable building codes and structural specifications for fastener spacing and torque requirements specific to the assembly.
