Description
x🔧 Full Product Description:
These SAE Extra Thick Flat Washers are crafted for precision and performance in high-stress environments. Made from Grade 8 thru-hardened carbon steel, these washers are engineered to withstand extreme torque, tension, and vibration without losing structural integrity.
SAE washers feature a smaller outer diameter (OD) than USS-style washers, making them ideal for use where spacing and clearance are tight—especially in automotive, aerospace, and mechanical equipment. The extra thickness enhances load distribution and provides increased spacing when needed in bolted joints.
Finished with a durable yellow zinc chromate coating, these washers resist corrosion and provide a professional, high-visibility appearance.
Built to SAE and ASTM standards, these washers are an essential choice when durability, precision, and corrosion resistance are non-negotiable.
✅ Key Features:
-
Material: Grade 8 Carbon Steel (SAE J429-compliant)
-
Hardness: Thru-Hardened (Rockwell C38–45)
-
Finish: Yellow Zinc Plated (Zinc Chromate) – Corrosion Resistant
-
Standard: SAE (Smaller OD than USS for precision applications)
-
Thickness: Extra Thick – For High Load Distribution & Spacer Applications
Use Cases: Automotive, Industrial Machinery, Tooling, Heavy Equipment, Construction
