Value Collection 706058MSC Flange Bolt 3/8-16 Unc 1in Alloy Steel

Product Description

The VALUE COLLECTION 706058MSC is a smooth flange bolt designed for high-strength fastening applications where a built-in bearing surface is needed. Machined from alloy steel to a 170,000 psi material grade and certified to ASTM A574, this bolt delivers consistent clamping force without a separate washer. The smooth flange distributes load across a 9/16 inch diameter bearing face, reducing the risk of surface damage or embedment. The 3/8-16 UNC thread is fully threaded along the 1 inch length under head, and the 12-point drive allows high torque input in tight clearance situations. Installers working in mechanical, HVAC, plumbing, and structural assembly applications will find this bolt well suited to demanding service conditions.

This bolt is appropriate for both light commercial and industrial fastening tasks where standard hex bolts are insufficient. The 12-point drive profile is commonly used in engine, compressor, and mechanical equipment assembly where precise torque application and access limitations are a concern. The fully threaded shank makes it a practical choice for short-length clamping with full thread engagement across the joint. No finish coating is applied, making it suitable for applications where bare or subsequently plated hardware is specified.

Key Features

• Alloy steel construction rated to 170,000 psi tensile strength per ASTM A574
• Smooth flange provides integrated bearing surface — no separate washer required
• Flange diameter range of 0.550 to 0.562 inches for consistent load distribution
• Fully threaded 3/8-16 UNC shank over 1 inch length under head
• 12-point drive accepts 3/8 inch drive sockets for high-torque applications
• Bright uncoated finish — bare alloy steel, no plating applied

Compatibility

Designed as a standard ASTM A574 smooth flange bolt for use in mechanical assemblies, equipment frames, and structural joints requiring 3/8-16 UNC threaded fasteners with an integrated flange bearing surface.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with high-strength fastener torque requirements. Verify that the mating threads and joint materials are compatible with uncoated alloy steel before installation. Use a calibrated torque wrench and a 12-point socket sized for the 3/8 inch drive to achieve accurate clamping load. Clean and inspect all mating surfaces and threads prior to assembly to ensure full thread engagement.
