Value Collection 706158MSC Flange Bolt 3/8-16 Unc 2-1/2in

Product Description

The VALUE COLLECTION 706158MSC is a smooth flange bolt engineered for high-strength fastening applications where a load-distributing flange face eliminates the need for a separate washer. Built from alloy steel rated at 170M psi tensile strength and conforming to ASTM A574, this bolt delivers reliable clamping force in demanding mechanical and structural assemblies. The 3/8-16 UNC thread and 12-point drive head allow for high torque application with standard or crowfoot socket tooling. Partial threading with 1 inch of thread engagement preserves shank strength across the grip length. Licensed tradespeople and industrial maintenance technicians are the primary installers.

This bolt is suited for use in mechanical assemblies, structural steel connections, HVAC equipment mounting, pump and compressor frames, and general industrial maintenance where a flanged fastener is specified. The smooth flange face bears evenly against the mating surface, spreading the clamping load and reducing the risk of surface damage or fastener pull-through. The uncoated finish is appropriate for dry indoor installations or applications where a field-applied coating or lubricant will be specified by the job engineer.

Key Features

• Alloy steel construction rated to 170M psi tensile strength for high-load applications
• Conforms to ASTM A574 standard for socket head cap screws and flange bolts
• Smooth flange face distributes clamping load without a separate washer
• 3/8-16 UNC partially threaded shank with 1 inch of thread length
• 12-point drive accepts standard socket or crowfoot tooling for high-torque installation
• Uncoated finish for use where coating selection is field- or engineer-specified

Compatibility

Designed as a direct-fit replacement or OEM-style flange bolt for mechanical, structural, and equipment-mounting applications requiring a 3/8-16 UNC smooth flange fastener conforming to ASTM A574.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician following the torque specifications provided by the equipment manufacturer or project engineer. De-energize and lock out all equipment before fastener service. Use a 12-point socket sized to the 3/8 inch drive to avoid rounding the head. Verify thread engagement, flange seating, and torque requirements against applicable codes and the assembly drawing before final tightening.
