Armor Coat UST235763 Hex Head Cap Screw 5/16-24 Grade 8

Product Description

The ARMOR COAT UST235763 is a Grade 8 steel hex head cap screw with a 5/16-24 UNF thread and a 1-1/2-inch length under head. It features partial threading and an Armor Coat finish for enhanced corrosion resistance. This fastener meets ASME B18.2.1 and SAE J429 dimensional and strength standards, making it appropriate for high-load mechanical assemblies in HVAC, plumbing, electrical, and general industrial trade applications. Licensed trades and maintenance professionals use this screw where a strong, corrosion-resistant UNF fastener is required.

This cap screw suits inch-measurement fastening applications requiring a fine-thread UNF specification. The partial threading supports clamping force in through-bolt and flanged joint configurations. Its Grade 8 strength rating makes it suited for equipment mounting, bracket installation, and structural mechanical assemblies in both residential and commercial service environments.

Key Features
