S-91844A370 0.41" ID x 1" OD Curved Washers

Key Features & Benefits at a Glance

• Enhanced load distribution through curved design prevents surface damage and maintains joint integrity under vibration
• Superior corrosion resistance with zinc-plated steel construction for extended service life in harsh environments
• Precision dimensional compatibility with 0.41" ID perfectly matching 3/8" screw sizes and 1" OD fitting 7/8" tube applications
• Consistent performance ensured by Rockwell B40 hardness rating for reliable mechanical properties
• Regulatory compliance with RoHS 3 and REACH standards for safe use across global industrial markets
• Optimized thickness range (0.050-0.070") provides flexibility while maintaining structural stability
• Reduced maintenance requirements through durable material selection and protective surface treatment

Professional Applications & Engineering Value

These zinc-plated steel curved washers deliver critical engineering solutions where standard flat washers fall short. The distinctive curved design transforms axial loads into radial pressure, effectively distributing stress across wider surface areas to prevent material deformation in 3/8" screw applications. This proves particularly valuable in assembly operations involving 7/8" tube OD connections, where vibration-induced loosening commonly compromises joint security. The Rockwell B40 hardness ensures consistent performance under cyclic loading, while the zinc plating creates a sacrificial barrier against galvanic corrosion in industrial environments. By addressing common failure points in mechanical fastening systems, these curved washers extend equipment lifespan and reduce maintenance intervals across automotive, construction, and heavy machinery sectors.
