Value Collection 822693MSC Flange Bolt 5/16-18 Unc 1 in Grade 8

Product Description

The VALUE COLLECTION 822693MSC is a smooth flange bolt designed for high-strength fastening applications requiring a built-in bearing surface. The flange distributes clamping load across a wider area without the need for a separate washer. This bolt features a 5/16-18 UNC fully threaded shank with 1 inch of thread length under the head, a hex drive, and a smooth 11/16-inch (0.6875 inch) flange diameter. Manufactured from Grade 8 alloy steel with a phosphate and oil finish, it meets SAE J429 standards and is suited for heavy-duty mechanical and structural assemblies. Electricians, HVAC technicians, plumbers, and general trade mechanics commonly use this fastener in equipment mounting and panel attachment work.

This smooth flange bolt is appropriate for residential and commercial trade applications where vibration resistance and load distribution are priorities. The fully threaded shank allows engagement along the entire bolt length, making it effective in thinner material assemblies and short-grip applications. The phosphate and oil finish provides a baseline level of corrosion resistance suitable for indoor and protected environments. This fastener is sold individually but requires a minimum order quantity of 100 pieces per order.

• 5/16-18 UNC thread form, fully threaded along the entire 1-inch length under head
• Smooth flange with 11/16-inch (0.6875 inch) diameter provides integrated bearing surface without a separate washer
• Grade 8 alloy steel construction for high tensile and proof load strength
• Phosphate and oil finish for corrosion resistance in indoor and protected environments
• Hex drive compatible with standard wrenches and sockets
• Meets SAE J429 fastener standard

Compatibility

Designed as a standard inch-series smooth flange bolt for use in mechanical, structural, and equipment-mounting applications requiring a 5/16-18 UNC thread and Grade 8 strength rating.

Installation Notes

Installation is performed with a standard hex wrench or socket driver sized for a 5/16-inch hex head. Ensure mating threads are clean and free of debris before driving. Do not exceed the rated proof load for Grade 8 fasteners in the application. Always follow applicable mechanical codes and equipment manufacturer torque guidance when specified in the job documentation.
