Value Collection C39055 Smooth Flange Bolt 3/4-10 Unc

Product Description

The VALUE COLLECTION C39055 is a smooth flange bolt designed for high-strength fastening applications where a wide bearing surface is needed without a separate washer. Built from Grade 8 alloy steel in an uncoated finish, this bolt uses a 3/4-10 UNC thread and measures 2-1/2 inches in length under the head with partial threading. The integrated smooth flange distributes clamping load evenly across the mating surface, reducing the risk of surface damage under torque. It is installed with a standard hex drive. Licensed trade professionals and maintenance technicians working on mechanical assemblies, HVAC equipment frames, and structural hardware will find this bolt suited for heavy-duty fastening needs.

This bolt is appropriate for use in industrial, commercial, and trade-maintenance settings where Grade 8 fastener strength is required. Partially threaded shanks allow for tighter clamping in joints where the unthreaded portion spans the interface between two materials. The smooth flange eliminates the need for a flat washer in many standard applications, streamlining assembly and reducing hardware count on the job.

Key Features

• Grade 8 alloy steel construction for high-strength fastening
• 3/4-10 UNC thread standard for broad compatibility with inch-series hardware
• Partially threaded shank for improved clamping across material interfaces
• Smooth integrated flange at 1-19/32 inches (1.5938 inches) diameter replaces need for a separate flat washer
• Hex drive for use with standard wrenches and sockets
• Uncoated finish; meets IFI 111 and SAE J429 standards

Compatibility

Designed as an OEM-style replacement or service fastener for mechanical assemblies requiring 3/4-10 UNC Grade 8 inch-series flange bolts.

Installation Notes

Installation should be performed by qualified mechanical or trade technicians familiar with high-strength fastener torque requirements for Grade 8 hardware. Always de-energize and lock out equipment before replacing structural or equipment-frame fasteners. Use calibrated torque equipment and follow the applicable fastener torque specifications for the equipment being serviced. Do not substitute Grade 8 fasteners with lower-grade hardware in structural or high-load applications.
