Value Collection 706118MSC Smooth Flange Bolt 3/8-16 Unc

Product Description

The VALUE COLLECTION 706118MSC is a smooth flange bolt designed for applications requiring a clean bearing surface and secure clamping force without a separate washer. Manufactured from alloy steel to a 170M PSI material grade and certified to ASTM A574, this fastener delivers high tensile strength suited for demanding mechanical assemblies. It features a 3/8-16 UNC thread with a 1-3/4 inch length under head and is partially threaded with 1 inch of thread length, giving it solid grip in through-hole and tapped-hole installations. The 12-point drive head provides high torque engagement with standard socket tooling.

This flange bolt is appropriate for general industrial, mechanical, and equipment assembly applications where alloy steel fasteners are specified. The smooth flange distributes clamping load over a wider surface area, eliminating the need for a separate flat washer in many installations. It is commonly used in machinery frames, brackets, flanged joints, and structural assemblies across manufacturing and maintenance environments. Licensed mechanics, millwrights, and industrial maintenance technicians are the typical installers.

Key Features

• Alloy steel construction rated to 170M PSI for high-strength fastening
• Certified to ASTM A574 standard for socket head cap screws
• 3/8-16 UNC thread — partial thread with 1 inch of threaded length
• 12-point drive head accepts standard 3/8 inch socket for high-torque installation
• Smooth flange diameter of 9/16 inches (0.5500 to 0.5620 inches) provides integral load distribution
• Bright uncoated finish — suitable where coating is not required or post-treatment will be applied

Compatibility

Designed as a standard ASTM A574 alloy steel smooth flange bolt for use in industrial and mechanical assemblies requiring 3/8-16 UNC partially threaded fasteners.

Installation Notes

Install using a 3/8 inch 12-point socket and appropriate torque wrench per the fastener specification and joint design requirements. Ensure mating threads are clean, undamaged, and free of debris before installation. Follow applicable industry standards for fastener torque values based on the joint material and lubrication condition. Do not exceed the rated tensile strength of the fastener or the shear rating of the base material.
