Key Features & Benefits at a Glance
- Superior corrosion resistance in harsh environments due to 316 stainless steel construction, ideal for marine, chemical, and outdoor applications.
- Precise dimensional fit with 0.125" inner diameter and 0.25" outer diameter ensures reliable performance and easy installation for No. 4 screws.
- Enhanced load distribution and surface protection, reducing wear and extending the lifespan of assemblies.
- Compliance with ASME B18.21.1 standards guarantees consistent quality, interchangeability, and reliability in industrial settings.
- RoHS 3 and REACH compliance ensures environmental safety and meets regulatory requirements for hazardous substance restrictions.
- Durable and non-magnetic properties provide long-term stability in demanding conditions without interference in sensitive equipment.
Professional Applications & Engineering Value
These 316 stainless steel flat washers are engineered to address common industrial challenges, such as corrosion-induced failure and component misalignment. The ASME B18.21.1 compliance ensures precise dimensions and uniform thickness (0.028-0.036"), which helps prevent loosening under vibration and distributes loads evenly to protect surfaces. Ideal for industrial applications like machinery assembly, marine hardware, and chemical processing equipment, the corrosion-resistant material and inch system sizing (e.g., 0.125" ID for No. 4 screws) provide reliable performance in aggressive environments, reducing maintenance costs and downtime.
Specification Summary & Compliance
This flat washer features an inner diameter of 0.125", outer diameter of 0.25", and thickness range of 0.028-0.036", designed for No. 4 screw sizes in the inch measurement system. It conforms to ASME B18.21.1 specifications for dimensional accuracy and performance. Additionally, it is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to environmental and safety standards for hazardous substances.
