Value Collection -34700-11/2 Flange Bolt 5/8-11 Unc 10 Pack

Product Description

The VALUE COLLECTION -34700-11/2 is an alloy steel flange bolt designed for heavy-duty fastening applications in mechanical, industrial, and trade installations. This bolt features a 5/8-11 UNC thread size with a 1.5 inch length under the head and a built-in flange bearing surface that distributes clamping load without a separate washer. The 12-point drive accepts a socket or box wrench for high-torque installation. Manufactured to ASME B18.3 standards, this bolt delivers consistent dimensional accuracy and material integrity. Sold in a pack of 10 with a plain finish, it suits applications where corrosion resistance is managed by the installer or ambient conditions are controlled.

This flange bolt is suited for mechanical assemblies, equipment mounting, pipe flange connections, and structural fastening in residential and commercial settings. The UNC thread form is the standard inch-series coarse thread, making it compatible with a wide range of tapped holes and standard nuts. Trades including pipefitters, millwrights, HVAC installers, and general mechanical contractors regularly use this bolt size in equipment pads, frame assemblies, and flanged joint work. The plain finish means no coating interference when electrical bonding or tight dimensional tolerances are required at the joint.

Key Features

• 5/8-11 UNC thread size for broad compatibility with standard inch-series hardware
• 1.5 inch length under head suits medium-depth fastening applications
• Integrated flange distributes clamping load, eliminating the need for a separate washer
• 12-point drive allows high-torque installation with a socket or box wrench
• Alloy steel construction provides strength suited for heavy mechanical fastening
• Manufactured to ASME B18.3 dimensional standards for consistent fit and interchangeability

Compatibility

Designed as a standard inch-series UNC flange bolt for use in mechanical assemblies, equipment mounting, and flanged joint applications requiring a 5/8-11 thread.

Installation Notes

Installation should be performed by a qualified mechanic, pipefitter, or trade professional familiar with bolted joint procedures. Power down or depressurize the system before disassembling any flanged connections. Use a calibrated torque wrench and follow the joint or equipment manufacturer specifications for final torque values, as none are specified for this fastener alone. Inspect thread engagement and flange seating surface condition before torquing to ensure a secure, leak-free joint.
