S-94744A417 0.938" ID x 2.25" OD ASME B18.21.1 ASME Washers

Key Features & Benefits at a Glance

• Superior corrosion protection with zinc plating for extended service life in harsh industrial environments
• Precise dimensional fit with 0.938" ID and 2.25" OD ensuring optimal load distribution for 7/8" screw applications
• Enhanced durability through zinc-plated steel construction resisting deformation under heavy loads
• Industry-standard compliance with ASME B18.21.1 specifications guaranteeing consistent performance and interchangeability
• Environmental responsibility with RoHS 3 and REACH compliance meeting global regulatory requirements
• Reliable thickness range of 0.146-0.174" providing consistent spacing and vibration resistance
• Broad industrial compatibility with inch system measurement for seamless integration into existing assemblies

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these zinc-plated steel flat washers deliver critical protection against corrosion and mechanical stress. The ASME B18.21.1 compliant design ensures precise dimensional accuracy, preventing loosening under vibration while distributing load evenly across fastened surfaces. Ideal for heavy-duty equipment, structural assemblies, and machinery maintenance, the zinc plating creates a sacrificial barrier that significantly extends component lifespan in corrosive environments. The optimized 0.938" ID provides secure seating on 7/8" fasteners, while the generous 2.25" OD maximizes bearing surface area - effectively solving common issues of surface damage, bolt head embedment, and joint failure in high-stress applications.

Specification Summary & Compliance
