Value Collection 701058MSC Flange Bolt 1/4-20 Unc 1 in Alloy Steel

Product Description

The VALUE COLLECTION 701058MSC is a smooth flange bolt designed for applications requiring a secure, load-distributing fastener without a separate washer. Built from alloy steel rated at 170,000 psi tensile strength and certified to ASTM A574, this bolt delivers reliable clamping force in high-stress assemblies. The integrated smooth flange spreads the bearing load across the mating surface, reducing the risk of pull-through in softer materials. Fully threaded along its 1-inch length under head, it accepts engagement along the entire shank — useful in thin-material or close-tolerance joints. Trades and maintenance professionals working in industrial, mechanical, and equipment assembly applications install this bolt where flange-style fasteners are specified.

This bolt is suited for structural and mechanical assemblies in industrial maintenance, HVAC equipment fabrication, and general trade applications where a 1/4-20 UNC threaded fastener with a smooth flange head is required. The 12-point drive allows high torque application in confined spaces with standard 1/4-inch drive tooling. The uncoated finish is appropriate for indoor or controlled-environment use where corrosion protection is not a primary requirement.

Key Features

• Alloy steel construction rated to 170,000 psi tensile strength per ASTM A574
• Smooth flange head distributes clamp load without a separate washer
• Fully threaded 1-inch length under head for maximum thread engagement
• 12-point drive accepts 1/4-inch drive tooling for high-torque installation in tight spaces
• Flange diameter of 0.365 to 0.375 inches for consistent seating
• Uncoated finish suitable for controlled-environment assemblies

Compatibility

Designed as a standard 1/4-20 UNC fully threaded smooth flange bolt for use in mechanical and industrial assemblies specifying ASTM A574 alloy steel fasteners with a 12-point drive.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a 12-point socket or bit driver sized for the 1/4-inch drive. De-energize and lock out any equipment before fastener replacement or assembly work. The uncoated finish provides no corrosion resistance — avoid use in wet or chemically exposed environments unless additional protection is applied. Follow the applicable equipment manufacturer torque specifications for 1/4-20 fasteners at the 170,000 psi grade.
