Value Collection C39050 Flange Bolt 5/8-11 Unc 2-3/4 in

Product Description

The VALUE COLLECTION C39050 is a smooth flange bolt designed for structural and mechanical fastening applications where a built-in bearing surface is needed. It features a 5/8-11 UNC thread size with a 1-1/2 inch thread length and an overall length under head of 2-3/4 inches. The integrated smooth flange measures 1-21/64 inches (1.3281 inches) in diameter, distributing clamp load across a wider surface area without a separate washer. Manufactured from Grade 8 alloy steel with a bright uncoated finish, this bolt meets IFI 111 and SAE J429 standards. Licensed tradespeople and maintenance technicians working on heavy equipment, industrial machinery, or structural assemblies are the primary installers.

This bolt is suited for high-strength bolted joint applications in residential, commercial, and industrial settings. The partial threading leaves a smooth shank section that resists shear loads in close-tolerance holes. Typical install scenarios include equipment mounting, frame assemblies, and structural connections where Grade 8 tensile strength is required. Sold in a package quantity of 10, it is appropriate for both single-job use and shop stock replenishment.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with high-strength fastener procedures. Inspect the mating threads and seating surface before installation to ensure freedom from debris and damage. Use a calibrated torque wrench and follow the applicable torque specification from the relevant equipment service manual or applicable industry standard for 5/8-11 Grade 8 fasteners. Do not mix Grade 8 bolts with lower-grade nuts or hardware, as mismatched grades compromise joint integrity.
