It features a 1-7\/16 inch inner diameter, 2-3\/4 inch outer diameter, and 5\/32 inch thickness in a plain uncoated finish. SAE flat washers distribute load across the bearing surface of a fastener, reducing stress concentrations and protecting the mating material. This washer conforms to SAE dimensional standards for inch-series fasteners and is sold in a minimum order quantity of 25 pieces. It is appropriate for general mechanical assembly, structural connections, and maintenance work across HVAC, plumbing, electrical, and industrial applications.\u003c\/p\u003e\n\u003cp\u003eThis washer is used wherever a 1-3\/8 inch screw or bolt requires a load-spreading or spacing element at the joint. Plain steel construction makes it well suited for indoor installations, painted assemblies, or applications where the installer will apply their own corrosion protection. It is handled by millwrights, pipefitters, HVAC mechanics, electricians, and general maintenance technicians in both residential and commercial settings. The SAE washer series provides a wider outer diameter relative to the screw size compared to USS washers, making it the preferred choice when bearing surface coverage is the primary concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSAE flat washer profile provides wider load-bearing surface than standard USS sizing\u003c\/li\u003e\n  \u003cli\u003e1-7\/16 inch inner diameter fits 1-3\/8 inch screw or bolt shanks with standard clearance\u003c\/li\u003e\n  \u003cli\u003e2-3\/4 inch outer diameter distributes clamping load across a broad contact area\u003c\/li\u003e\n  \u003cli\u003e5\/32 inch thickness provides rigid support without excessive stack height\u003c\/li\u003e\n  \u003cli\u003ePlain steel finish compatible with field-applied coatings or use in dry interior environments\u003c\/li\u003e\n  \u003cli\u003eSold in multiples of 25 pieces to support job-site and shop stocking quantities\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service-stock flat washer for use with 1-3\/8 inch inch-series fasteners in mechanical, structural, and trade assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall flat washers between the fastener head or nut and the mating surface, ensuring the washer sits flat and fully covers the hole without overlapping adjacent hardware. Verify the inner diameter clears the fastener shank freely before assembly. Follow applicable mechanical and building codes for fastener torque and joint design requirements.
