Value Collection 706078MSC Flange Bolt 3/8-16 Unc 1-1/4in

Product Description

The VALUE COLLECTION 706078MSC is a smooth flange bolt designed for high-strength fastening applications where a built-in bearing surface is required. Manufactured from alloy steel with a 170M PSI material grade, this bolt meets ASTM A574 standards for socket head cap screws and equivalent high-strength fasteners. The 3/8-16 UNC thread is fully threaded along the 1-1/4 inch length under head, providing maximum thread engagement throughout the grip range. The smooth flange measures 9/16 inch in diameter (0.550 to 0.562 inch decimal range) and distributes clamp load evenly without the need for a separate washer. The 12-point drive allows high torque input in tight spaces. Finish is bright and uncoated, suitable for dry or protected environments.

This bolt is appropriate for mechanical assembly, structural fastening, and equipment maintenance applications across HVAC, plumbing, electrical, and general industrial trades. The ASTM A574 rating makes it a common choice where high-strength, compact-head fasteners are specified. It is sold in a minimum order quantity of 10 units, with a package quantity of 1. Trades installing equipment frames, brackets, flanged connections, or mechanical assemblies will find this bolt a direct fit for standard 3/8-16 UNC tapped holes requiring a flange-style head.

Compatibility

Designed for use in any application requiring a 3/8-16 UNC fully threaded smooth flange bolt meeting ASTM A574 specifications. Fits standard 3/8-16 UNC tapped holes across mechanical, HVAC, plumbing, and electrical equipment assemblies.

Installation Notes

Installation should be performed by a qualified mechanic or trade professional familiar with high-strength fastener requirements. Ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate thread lubricant or threadlocker only as specified by the equipment manufacturer. Do not exceed the rated material strength when applying torque; consult the applicable fastener torque specification table for 3/8-16 UNC alloy steel fasteners.
