Armor Coat UST235772 Hex Head Cap Screw 3/8-16 X 2.5 in Grade 8

Product Description

The ARMOR COAT UST235772 is a Grade 8 steel hex head cap screw with a 3/8-16 UNC thread and a 2.5-inch length under head. It features partial threading and an Armor Coat finish for corrosion resistance in demanding environments. Built to ASME B18.2.1 and SAE J429 standards, this fastener is suited for high-strength bolting applications where precise torque loads and reliable clamping force are required. Mechanical and structural contractors, industrial maintenance technicians, and HVAC installers rely on Grade 8 hardware where standard fasteners are not adequate for the load or service conditions.

This cap screw is appropriate for use in structural assemblies, equipment mounting, and mechanical connections that require high-tensile fasteners. The partial threading design provides a smooth shank section for shear loading applications and precision alignment. The Armor Coat finish adds a layer of protection against rust and chemical exposure, making it a practical choice for both indoor mechanical rooms and outdoor or semi-exposed installations.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 3/8-16 UNC thread for compatibility with standard inch-series nuts and tapped holes
• Partial threading with smooth shank section supports shear load and alignment applications
• Armor Coat finish provides corrosion and chemical resistance
• Meets ASME B18.2.1 and SAE J429 dimensional and mechanical standards

Compatibility

Designed for use with standard 3/8-16 UNC inch-series hex nuts, locknuts, and tapped holes conforming to ASME and SAE specifications. Suitable for structural and mechanical bolting applications requiring Grade 8 fastener performance.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with fastener torque requirements for Grade 8 hardware. De-energize and lock out all equipment before replacing or installing fasteners in live assemblies. Use calibrated torque tools and consult applicable engineering specifications or equipment manufacturer guidelines for proper torque values. Do not mix Grade 8 fasteners with lower-grade nuts or washers, as mismatched hardware can reduce joint integrity.
