Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction for extended service life in harsh industrial environments
- Precise square hole alignment with 0.204" inside width ensures secure fit and prevents rotation with No. 10 screws
- Optimal load distribution through 0.437" OD design that minimizes surface pressure and material stress
- Consistent performance maintained by controlled thickness range of 0.025-0.035" for reliable spacing and tension
- Environmental compliance assurance with RoHS 3 and REACH compliance for global manufacturing applications
- Enhanced assembly efficiency through standardized inch measurements that streamline installation processes
- Durable steel core provides structural integrity for demanding mechanical and industrial applications
Professional Applications & Engineering Value
These zinc-plated steel washers with square hole design solve critical assembly challenges in industrial settings where vibration resistance and component stability are paramount. The precisely engineered 0.204" inside width creates an anti-rotation interface with No. 10 screws, eliminating loosening in high-vibration applications from machinery to automotive assemblies. The zinc plating provides essential corrosion protection, extending component life in environments exposed to moisture, chemicals, or outdoor conditions. With their 0.437" OD and controlled thickness, these square hole washers distribute clamping forces evenly, preventing surface damage to softer materials while maintaining consistent bolt tension in critical connections.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 0.437" outer diameter, 0.204" inside width, and thickness ranging 0.025-0.035". Designed specifically for No. 10 screw applications in inch measurement systems. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial and commercial applications.
