Professional Applications & Engineering Value
This 18-8 stainless steel flat washer is engineered to address common industrial challenges like corrosion-induced failure and uneven load distribution. Its inch-system dimensions (0.625" OD x 0.344" ID) ensure precise alignment with 5/16" screws, preventing misalignment in machinery, automotive, and construction assemblies. The stainless steel material offers excellent resistance to oxidation and chemicals, extending service life in demanding environments. By providing a stable bearing surface, it reduces wear on connected components and maintains bolt tension, crucial for vibration-prone applications. Its Rockwell B83 hardness guarantees structural integrity under repetitive stress, making it a trusted choice for heavy-duty washers in OEM and MRO sectors.
Specification Summary & Compliance
This flat washer features inch-system measurements with an inner diameter of 0.344", outer diameter of 0.625", and thickness ranging from 0.079" to 0.098", designed for 5/16" screw size applications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring adherence to environmental and safety regulations. Manufactured from 18-8 stainless steel with a hardness of Rockwell B83, it meets industry requirements for durability and performance in mechanical assemblies.
