Professional Applications & Engineering Value
This M8 316 stainless steel flat washer with acrylic adhesive addresses critical engineering challenges in industrial assembly and maintenance. The 316 stainless steel material provides exceptional corrosion resistance, making it suitable for applications in marine, chemical processing, and food industry equipment where moisture and corrosive agents are present. The integrated 1mm acrylic adhesive layer eliminates the need for separate bonding agents, simplifying installation while ensuring vibration-resistant sealing for M8 screw fastenings. This combination is ideal for securing panels, electronic enclosures, and machinery components that require reliable performance under thermal cycling from 50°F to 200°F. By conforming to DIN 125 standards, it guarantees precise dimensions and consistent load distribution, reducing the risk of loosening and material fatigue in high-stress environments.
Specification Summary & Compliance
This flat washer meets DIN 125 specifications for dimensional accuracy, with an inner diameter of 8.4mm, outer diameter of 19mm, and thickness of 1mm, ensuring proper fit with M8 metric screws. It is manufactured from 316 stainless steel with a hardness of Rockwell B70 and features a 1mm acrylic adhesive backing. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety requirements for industrial use.
