Value Collection 47055 Smooth Flange Bolt 3/8-16 Unc Grade 8

Product Description

The VALUE COLLECTION 47055 is a smooth flange bolt designed for fastening applications that require a wide bearing surface without a separate washer. The bolt features a 3/8-16 UNC thread, is fully threaded at 1-1/4 inches length under head, and is manufactured from Grade 8 alloy steel for high-strength performance. A zinc yellow dichromate finish provides corrosion resistance in demanding environments. The hex drive head allows installation with standard wrenches or sockets. This fastener meets IFI 111 and SAE J429 standards, making it suitable for structural and mechanical assemblies in trade and industrial settings.

This smooth flange bolt is used in mechanical, structural, and equipment-mounting applications where a low-profile, washer-style bearing surface is needed. The smooth flange distributes clamping load across a 13/16-inch flange diameter, reducing the risk of surface damage or fastener pull-through. Typical install scenarios include equipment frames, brackets, and assemblies in HVAC, plumbing, and light industrial environments. It is sold in minimum order quantities of 100 pieces, making it suited for contractors and maintenance operations that require bulk fastener stock.

Installation Notes

Install using a standard hex wrench or socket driver sized for the bolt head. Ensure mating threads are clean and free of debris before installation. Do not exceed the torque rating appropriate for Grade 8 fasteners at this thread size as specified by your application engineering reference. Follow applicable mechanical codes and manufacturer guidelines for the assembly being serviced.
