Key Features & Benefits at a Glance
- Exceptional load distribution with 3" OD and 1.625" ID for superior surface contact and reduced point loading on assemblies
- Enhanced corrosion resistance through black corrosion-resistant coating, extending service life in harsh industrial environments
- High-strength performance backed by Grade 8 classification and Rockwell C38 hardness for demanding applications
- Precise dimensional compatibility with 1 1/2" screw sizes and controlled thickness (0.136-0.160") for reliable fitment
- Industry-standard compliance with ASME B18.21.1 specifications ensuring consistent quality and interchangeability
- Environmental regulation adherence through RoHS 3 and REACH compliance for safe global sourcing
- Durable steel construction providing long-term reliability under high-stress conditions
Professional Applications & Engineering Value
This Grade 8 SAE flat washer delivers critical engineering solutions for heavy machinery, structural assemblies, and industrial equipment where vibration resistance and load distribution are paramount. The black corrosion-resistant coated steel construction prevents galvanic corrosion and withstands exposure to moisture, chemicals, and outdoor elements. With its 1.625" ID and 3" OD configuration, it effectively distributes clamping forces across wider surfaces, preventing joint loosening and material deformation in high-torque applications. The Rockwell C38 hardness ensures maintained dimensional stability under extreme pressures, making it ideal for construction equipment, automotive systems, and manufacturing infrastructure where fastener failure is not an option.
Specification Summary & Compliance
Manufactured to ASME B18.21.1 dimensional standards with precise inner diameter (1.625"), outer diameter (3"), and thickness range (0.136-0.160") for consistent performance. The washer meets Grade 8 strength classification requirements and demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring unrestricted use in global industrial supply chains.
