Value Collection -34699-11/2 Flange Bolt 1/2-13 Unc

Product Description

The VALUE COLLECTION -34699-11/2 is a 1/2-13 UNC flange bolt manufactured from alloy steel with a plain finish. The bolt features a 12-point drive head and a 1-1/2 inch length under head, conforming to ASME B18.3 standards. Flange bolts integrate a washer-style flange directly below the head, distributing clamping load across a wider bearing surface without requiring a separate washer. This design is well suited for fastening applications where load distribution and vibration resistance are priorities. Licensed tradespeople and maintenance technicians working on mechanical assemblies, HVAC equipment, plumbing fixtures, and structural connections commonly specify this bolt type.

This bolt is appropriate for use in both residential and commercial mechanical applications where a 1/2-13 UNC thread pattern and ASME B18.3 compliance are required. The alloy steel construction provides higher tensile strength than standard carbon steel, making it a practical choice for higher-stress assemblies. The plain finish is suitable for indoor or protected installations where corrosion exposure is limited. Each package contains 10 bolts, and orders are fulfilled in single-package multiples.

Key Features

• 1/2-13 UNC thread size with standard unified coarse thread form
• 1-1/2 inch length under head for defined grip-range applications
• 12-point drive head for high-torque tool engagement in tight spaces
• Alloy steel construction for elevated tensile strength
• Integrated flange distributes clamping load without a separate washer
• Meets ASME B18.3 fastener standard

Compatibility

Designed as an OEM-style replacement or service fastener for mechanical assemblies requiring a 1/2-13 UNC flange bolt conforming to ASME B18.3 in alloy steel with a plain finish.

Installation Notes

Installation is performed by qualified mechanical, HVAC, or plumbing tradespeople using a 12-point socket or bit driver sized for 1/2-inch drive applications. Ensure mating threads are clean and free of debris before installation. Do not exceed the torque specification listed in the equipment service manual for the assembly being fastened. Plain-finish alloy steel bolts are not rated for outdoor or high-moisture environments without additional corrosion protection.
