- Optimized load distribution from 0.7" outer diameter, reducing surface pressure and material stress
- Consistent performance maintained through controlled 0.055-0.065" thickness for reliable spacing
- Environmental compliance assurance with full RoHS 3 and REACH adherence for global supply chain compatibility
- Dimensional accuracy in inch system measurements for seamless integration with standard 3/8" fastener assemblies
- Long-term reliability in demanding applications due to stainless steel's inherent durability and strength
Professional Applications & Engineering Value
Engineered for industrial applications requiring secure fastening and corrosion resistance, these square hole washers solve critical rotation prevention challenges in machinery assembly. The 18-8 stainless steel composition provides excellent resistance to rust and chemical exposure, making them ideal for outdoor equipment, food processing machinery, and marine applications. The precise 0.405" inside width creates a positive lock with square-neck bolts, eliminating slippage under vibration while the 0.7" OD distributes clamping force effectively across surfaces. This combination of material properties and dimensional precision ensures long-term performance in high-stress environments where standard washers might fail.
Specification Summary & Compliance
This square hole washer features inch system dimensions including 0.7" outer diameter, 0.405" inside width, and controlled thickness between 0.055-0.065". Manufactured from 18-8 stainless steel for consistent performance, it's designed specifically for 3/8" screw applications. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring regulatory acceptance for industrial use across global markets.
