Value Collection C39037 Flange Bolt 1/2-13 Unc 2 in Grade 8

Product Description

The VALUE COLLECTION C39037 is a smooth flange bolt engineered for high-strength fastening applications where a built-in bearing surface is required. Sized at 1/2-13 UNC with a 2-inch length under head, this bolt features partial threading with 1-1/4 inches of thread engagement. The integrated smooth flange measures 1-5/64 inches (1.0781 inches decimal) in diameter and distributes clamp load across a wider surface area without the need for a separate washer. Manufactured from Grade 8 alloy steel and left uncoated, it meets IFI 111 and SAE J429 standards. Licensed tradespeople and maintenance professionals in mechanical, structural, and industrial applications install this fastener where controlled load distribution and tensile strength are priorities.

This flange bolt is suited for use in heavy-duty mechanical assemblies, structural connections, and industrial equipment where Grade 8 tensile strength is specified. The partially threaded shank allows for a firm grip in the unthreaded section, making it appropriate for applications requiring precise shear load handling. It is driven with a standard hex wrench or socket and installs in any orientation where a flanged fastener is called for. Minimum order quantity is 10 pieces per purchase.

Key Features

Compatibility

Designed as a standard 1/2-13 UNC smooth flange bolt for use in any application requiring a Grade 8 alloy steel flanged fastener conforming to IFI 111 and SAE J429 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with torque requirements for Grade 8 fasteners. Always consult the equipment manufacturer's torque specifications before installation. Ensure mating threads are clean and free of debris before driving the bolt. Do not use impact tools at full power without a torque-limiting setting, as over-torquing Grade 8 fasteners can induce thread damage or bolt failure.
