Value Collection C39034 Flange Bolt 1/2-13 Unc Grade 8 25pk

Product Description

The VALUE COLLECTION C39034 is a smooth flange bolt designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. It features a 1/2-13 UNC thread with a fully threaded shank measuring 1-1/4 inches in length under the head. The integrated smooth flange distributes clamping load over a wider bearing surface, reducing the need for a separate washer. Made from Grade 8 alloy steel with no finish coating applied, this bolt meets SAE J429 standards and is suited for applications where high tensile strength and dimensional consistency are required. Licensed trades and maintenance professionals working on equipment assemblies, mechanical supports, and structural connections rely on this grade for demanding service conditions.

This bolt is appropriate for use in residential and commercial mechanical systems, industrial equipment mounting, structural steel connections, and general-purpose fastening where UNC thread engagement and Grade 8 strength are specified. The smooth flange profile is well suited for sheet metal and thin-gauge panel assemblies where load spreading matters. Sold in a package quantity of 25, it fits high-volume service and repair workflows without requiring individual sourcing.

Key Features

• 1/2-13 UNC fully threaded shank for maximum thread engagement along the entire fastener length
• Smooth flange diameter of 1-5/64 inches (1.0781 inches) distributes clamping load without a separate washer
• Grade 8 alloy steel construction provides high tensile and proof load strength
• Uncoated finish maintains dimensional tolerances for close-fit applications
• Meets SAE J429 fastener standard for consistent mechanical properties
• Packaged in quantities of 25 to support production and service volume requirements

Compatibility

Designed as a standard UNC-thread smooth flange bolt for use in applications specifying 1/2-13 thread size, Grade 8 alloy steel, and SAE J429 compliance.

Installation Notes

Installation should be performed by qualified mechanical or maintenance trades familiar with SAE fastener grades and torque requirements for Grade 8 hardware. Always confirm thread engagement depth and mating material compatibility before installation. Use a calibrated torque wrench and follow the applicable fastener torque specification for the joint design — do not estimate by feel on structural connections. Inspect flange seating surface for debris or burrs before tightening to ensure proper load distribution.
