Value Collection R52001046 Hex Head Bolt 1/4-20 Grade 2

Product Description

The VALUE COLLECTION R52001046 is a 1/4-20 UNC hex head bolt designed for general-purpose fastening in light structural, mechanical, and utility applications. Manufactured from Grade 2 steel with a hot-dipped galvanized finish, this bolt provides corrosion resistance suited for outdoor or moisture-exposed installations. The shank measures 1 inch in length under the head and is partially threaded, with a 7/16-inch hex drive. It conforms to ANSI/ASME B18.2.1 dimensional standards. Licensed tradespeople and maintenance professionals use this fastener across HVAC equipment mounting, plumbing support brackets, electrical enclosures, and general mechanical assemblies.

This bolt is a standard inch-series fastener appropriate for residential and light commercial trade work. Partially threaded shanks are commonly specified where a smooth unthreaded grip length is needed between clamped surfaces, reducing the risk of thread engagement in load-bearing zones. The hot-dipped galvanized finish makes it a practical choice for exterior mounting hardware, rooftop equipment support, and corrosion-prone environments where plain steel fasteners would degrade prematurely.

Key Features

• 1/4-20 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• 1 inch length under head, partially threaded shank for proper grip in clamped assemblies
• Grade 2 steel construction meeting general commercial fastener strength requirements
• Hot-dipped galvanized finish for corrosion resistance in outdoor and wet environments
• 7/16-inch hex drive fits standard hex wrenches and sockets
• Conforms to ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2 standards

Compatibility

Designed as an OEM-style replacement and general-use fastener for any application requiring a 1/4-20 UNC hex head bolt with a 1-inch length under head and partially threaded shank.

Installation Notes

Installation requires a 7/16-inch hex wrench or socket driver. Always power down or de-energize equipment before replacing or installing fasteners on mechanical or electrical assemblies. Fastener tightening should follow the torque specifications provided by the equipment manufacturer or applicable code. Use appropriate personal protective equipment when working with galvanized hardware in confined or overhead spaces.
