Value Collection 822841MSC Flange Bolt 3/8-16 Unc Grade 8

Product Description

The VALUE COLLECTION 822841MSC is a smooth flange bolt designed for high-strength fastening applications in mechanical, industrial, and trade assembly work. It features a 3/8-16 UNC thread with a 2-3/4 inch length under head and partial threading of 1 inch. The integrated smooth flange distributes clamping load across a wider bearing surface, reducing the need for a separate washer in many installations. Manufactured from Grade 8 alloy steel with a phosphate and oil finish, it meets SAE J429 standards for tensile and proof load requirements. This bolt is suited for use by mechanics, millwrights, and trade professionals requiring a reliable, high-grade fastener.

This bolt is appropriate for use in structural, mechanical, and equipment assembly applications where Grade 8 strength is specified. The smooth flange design is common in automotive, HVAC equipment mounting, and general industrial fabrication where a clean bearing surface is required. The partial threading allows for a smooth shank section in the grip area, which is useful when the bolt passes through clearance holes before engaging threaded material.

Key Features

• 3/8-16 UNC thread for standard inch-series fastener compatibility
• Grade 8 alloy steel construction meets SAE J429 tensile and proof load requirements
• Smooth flange with 13/16 inch diameter distributes load without a separate washer
• Partially threaded with 1 inch of thread engagement length
• Phosphate and oil finish provides corrosion and galling resistance
• Hex drive for use with standard wrenches and sockets

Compatibility

Designed as a standard inch-series flange bolt for use in any application specifying a 3/8-16 UNC Grade 8 partially threaded fastener per SAE J429.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using a calibrated torque wrench sized for a 3/8 inch hex drive fastener. Always verify that the mating thread is clean and free of debris before installation. Follow the torque specifications provided by the equipment manufacturer or applicable assembly standard for Grade 8 fasteners at this thread size. Do not reuse bolts that show signs of thread damage, stretching, or corrosion.
