Value Collection 47153 Flange Bolt 5/8-11 Unc 3in Grade 8

Product Description

The VALUE COLLECTION 47153 is a smooth flange bolt designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 5/8-11 UNC thread size with a 3-inch length under the head and a 1-1/2-inch thread length, making it a partially threaded fastener. The integrated smooth flange distributes clamping load across a wider surface area without the need for a separate washer. Manufactured from Grade 8 alloy steel with a zinc yellow dichromate finish, this bolt delivers high tensile strength and corrosion resistance. It conforms to IFI 111 and SAE J429 standards. Licensed tradespeople and maintenance professionals working in heavy equipment, fabrication, and industrial maintenance will encounter this fastener regularly.

This bolt is suited for use in applications requiring a partially threaded, high-grade fastener with a built-in flange bearing surface. The smooth flange face makes it appropriate for installations where marring or gouging of the mating surface must be avoided. Common install scenarios include machinery mounting, structural steel connections, and equipment frames where Grade 8 strength is specified. The hex drive allows use with standard wrenches and sockets. This bolt is sold individually with a minimum order quantity of 25 pieces.

Key Features

• 5/8-11 UNC thread size with 3-inch length under head and 1-1/2-inch thread length
• Smooth flange face with 1-21/64-inch (1.3281 inches) flange diameter eliminates need for a separate washer
• Grade 8 alloy steel construction meets high tensile and proof load requirements per SAE J429
• Zinc yellow dichromate finish provides corrosion resistance in industrial environments
• Partially threaded shank allows for precise clamping without thread engagement through the full grip length
• Conforms to IFI 111 and SAE J429 fastener standards

Compatibility

Designed as a standard-dimension UNC partially threaded smooth flange bolt for use in any application specifying a 5/8-11 Grade 8 hex flange fastener per IFI 111 and SAE J429.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using standard hex wrenches or impact sockets rated for Grade 8 fasteners. Always confirm mating thread condition and hole clearance before installation. Do not use an impact driver set above the fastener grade rating, and never substitute a lower-grade bolt in a Grade 8-specified joint. Verify torque requirements against applicable engineering specifications for the assembly being serviced.
