Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc plating that protects against rust and extends service life in harsh industrial environments
- Precise dimensional fit with 0.094" ID and 0.25" OD ensuring perfect alignment and load distribution for No. 2 screws
- Enhanced durability from Rockwell B40 hardness that resists deformation under pressure and maintains fastener integrity
- Reliable load distribution with controlled thickness (0.028-0.036") to prevent surface damage and loosening in assemblies
- Industry-standard compliance with ASME B18.21.1 specifications guaranteeing consistent quality and interchangeability
- Environmental safety assurance through RoHS 3 and REACH compliance, meeting global regulatory requirements for industrial use
- Versatile industrial application as zinc-plated steel flat washers suitable for machinery, electronics, and general assembly
Professional Applications & Engineering Value
These zinc-plated steel flat washers deliver critical engineering solutions by addressing common industrial challenges like corrosion-induced failure and uneven load distribution. The zinc plating provides a sacrificial layer that significantly extends component life in humid or chemically aggressive environments, while the precise 0.094" ID and 0.25" OD dimensions ensure optimal seating for No. 2 screw applications, preventing misalignment and stress concentration. With Rockwell B40 hardness, these washers maintain structural integrity under vibration and dynamic loads, making them ideal for industrial assembly, electrical enclosures, and machinery where corrosion-resistant washers are essential for long-term reliability and reduced maintenance costs.
Specification Summary & Compliance
Manufactured to ASME B18.21.1 standards with inch system dimensions: 0.094" ID, 0.25" OD, and thickness range of 0.028-0.036". The zinc-plated steel construction ensures consistent performance, while full compliance with RoHS 3 (2015/863/EU) under exemption 6(a) and REACH (EC 1907/2006) regulations confirms environmental and safety adherence for global industrial supply chains.
