• Enhanced load distribution from the 1.375" outer diameter, reducing surface pressure and preventing material damage.
• Exceptional durability backed by Rockwell B68 hardness, resisting deformation under heavy mechanical stress.
• Compliance with environmental regulations, including RoHS 3 and REACH, for safe use in global industrial markets.
• Broad compatibility with inch-system fasteners, simplifying sourcing and replacement in existing assemblies.
• Consistent thickness range (0.084-0.097") for uniform performance and reliable spacing in critical applications.

Professional Applications & Engineering Value

This 18-8 stainless steel slotted washer is engineered to address common industrial challenges such as corrosion, vibration loosening, and uneven load distribution. The slotted design allows for quick alignment and secure fastening with 3/4" screws, making it ideal for heavy-duty applications in construction, machinery, and structural assemblies. Its corrosion-resistant properties ensure longevity in humid or chemical-exposed environments, while the precise slot dimensions (13/16" width, 1 1/8" depth) facilitate efficient installation without compromising grip strength. By distributing loads evenly across a 1.375" OD, this washer minimizes stress concentrations, reducing the risk of joint failure and maintenance costs in demanding operational settings.

Specification Summary & Compliance

This washer adheres to inch system measurements with precise dimensional tolerances, including an outer diameter of 1.375", thickness range of 0.084-0.097", and slot specifications of 13/16" width and 1 1/8" depth. It is manufactured from 18-8 stainless steel with a hardness of Rockwell B68 for consistent performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards ensures it meets stringent environmental and safety regulations, supporting its use in global industrial and construction projects.
