Value Collection 716118MSC Flange Bolt 5/8-11 Unc 1-3/4in Alloy Steel

Product Description

The VALUE COLLECTION 716118MSC is a smooth flange bolt designed for high-strength fastening applications in mechanical, industrial, and trade service work. It features a 5/8-11 UNC fully threaded shank with a length under head of 1-3/4 inches. The bolt is manufactured from alloy steel rated at 170M PSI and meets ASTM A574 standards, making it suitable for demanding structural and mechanical assembly tasks. The 12-point drive head provides high torque engagement with compatible sockets. The smooth flange distributes clamping load across a wider bearing surface without requiring a separate washer. The bright, uncoated finish is consistent with standard alloy steel hardware used in industrial and HVAC equipment assembly.

This flange bolt is used in applications where a high-strength, compact fastener with a built-in bearing flange is required. Typical uses include securing mechanical equipment housings, HVAC unit frames, pump mounts, and structural brackets where controlled clamping force and flange load distribution are priorities. The fully threaded configuration allows engagement along the entire shank length, making it well suited for shorter-grip fastening situations in metal-to-metal assemblies. Suitable for residential and light commercial mechanical installation work.

Key Features

• 5/8-11 UNC thread size with fully threaded shank for maximum engagement across the entire 1-3/4 inch length under head
• 170M PSI alloy steel construction meets ASTM A574 high-strength bolt standard
• 12-point drive head allows high-torque installation with standard 5/8 inch 12-point socket
• Smooth flange diameter of 15/16 inches (0.921 to 0.938 inches) distributes clamp load without a separate washer
• Bright uncoated finish suitable for dry or protected interior fastening environments

Compatibility

Designed as a high-strength replacement or service fastener for mechanical and industrial assemblies requiring a 5/8-11 UNC smooth flange bolt conforming to ASTM A574.

Installation Notes

Installation should be performed by a qualified mechanic or trade professional familiar with high-strength fastener requirements. Use a 5/8 inch 12-point socket and a calibrated torque wrench to achieve proper clamp load per the equipment manufacturer specification. De-energize and lock out all equipment before fastener replacement or service. Do not substitute this bolt in applications requiring a coated or corrosion-resistant finish without verifying material compatibility.
