Armor Coat UST236044 Sae Flat Washer 5/8 Inch Alloy Steel

Product Description

The ARMOR COAT UST236044 is an SAE flat washer machined from Grade 8 alloy steel, designed for use with 5/8-inch screws and bolts. It features an 11/16-inch inside diameter, a 1-5/16-inch outside diameter, and a 0.09-inch thickness, conforming to ASME B18.22.1 and ASTM F436 fastener standards. This washer distributes clamping load across the bearing surface, reducing fastener pull-through and protecting substrate materials from damage under high-torque installations. It is suited for structural, mechanical, and heavy-duty equipment assembly applications where consistent load distribution and corrosion-resistant hardware are required.

The UST236044 washer is intended for use in commercial and industrial fastening applications where Grade 8 alloy steel hardware is specified. Typical use cases include equipment mounting, structural steel connections, and machinery assembly in demanding environments. The SAE profile provides a wider bearing surface than USS-pattern washers, making it appropriate where tighter dimensional tolerances are required by specification or engineering drawings.

Key Features

• Grade 8 alloy steel construction for high tensile and shear strength applications
• SAE profile with 1-5/16-inch outside diameter provides broad load distribution
• 11/16-inch inside diameter fits 5/8-inch screws and bolts with proper clearance
• 0.09-inch thickness meets ASME B18.22.1 and ASTM F436 dimensional standards
• Inch measurement system; UNSPSC Code 31161807

Compatibility

Designed as an OEM-style replacement or direct-fit component for 5/8-inch fastener assemblies requiring SAE flat washers per ASME B18.22.1 and ASTM F436 specifications.

Installation Notes

Installation is typically performed by millwrights, ironworkers, pipefitters, or mechanical contractors working with structural or equipment-mount assemblies. Always de-energize and de-load the assembly before disassembling existing fastener groups. Use calibrated torque equipment appropriate to Grade 8 fastener specifications as defined by your project engineer or applicable code. Do not mix Grade 8 hardware with lower-grade fasteners in the same joint without engineering approval.
