Value Collection 822241MSC Flange Bolt 5/8-18 Unf 2-3/4 in Grade 8

Product Description

The VALUE COLLECTION 822241MSC is a smooth flange bolt designed for high-strength fastening applications in mechanical, industrial, and trade assembly work. It carries a 5/8-18 UNF thread specification and measures 2-3/4 inches in length under the head. The bolt is partially threaded with a 1-1/2 inch thread length, leaving a smooth shank section that helps resist shear loads. Manufactured from Grade 8 alloy steel with a phosphate and oil finish, it meets IFI 111 and SAE J429 standards. Hex drive configuration allows installation with standard hex wrenches or impact drivers. Machinists, millwrights, and trade technicians routinely use bolts of this type in structural and equipment assembly contexts.

This bolt is suited for high-load bolted joint applications where a fine-thread UNF specification is required for increased tensile strength and vibration resistance. The smooth flange distributes clamping load across a wider bearing surface, reducing the need for a separate washer in many applications. Typical use scenarios include mounting brackets, machinery frames, and structural steel assemblies where Grade 8 alloy steel strength is specified by design or maintenance requirements.

Key Features

• 5/8-18 UNF fine-thread specification for high tensile strength and vibration resistance
• Grade 8 alloy steel construction rated for demanding high-load applications
• Partially threaded shank with 1-1/2 inch thread length supports shear load capacity
• Smooth flange diameter of 1-21/64 inches (1.3281 inches) spreads clamping load without a separate washer
• Phosphate and oil finish provides corrosion inhibition and lubricity during installation
• Meets IFI 111 and SAE J429 fastener standards

Compatibility

Designed as a standard inch-series smooth flange bolt for use in any application requiring a 5/8-18 UNF partially threaded fastener meeting IFI 111 and SAE J429 specifications.

Installation Notes

Installation should be performed by a qualified technician familiar with fastener torque specifications appropriate to Grade 8 alloy steel bolts of this thread size. Confirm mating thread condition and clean threads before assembly. The phosphate and oil finish provides installation lubricity; follow the joint design torque spec to avoid overloading the fastener. Do not mix inch-series and metric fasteners in the same bolted joint.
