Key Features & Benefits at a Glance
- Enhanced Load Distribution with 0.5" OD and 0.281" ID for superior surface coverage and reduced point stress on 1/4" screw assemblies.
- Exceptional Durability from Rockwell B40 hardness steel, resisting deformation under high-torque and heavy-duty applications.
- Secure Anti-Rotation Design with a 0.45" clipped width, preventing washer spin-out during vibration or dynamic loading.
- Precision Fit & Consistent Performance due to tightly controlled 0.056-0.071" thickness, ensuring uniform clamping force.
- Corrosion Resistance from high-quality steel construction, extending service life in harsh industrial environments.
- Global Compliance Assurance with RoHS 3 and REACH standards, meeting international environmental and safety regulations.
- Broad Compatibility with inch-system fasteners, ideal for North American machinery and equipment specifications.
Professional Applications & Engineering Value
This steel clipped washer is engineered to solve critical assembly challenges in industrial applications where vibration loosening and material fatigue are common. The clipped design provides a positive locking mechanism, essential for automotive subframes, heavy machinery, and structural steel connections using 1/4" screws. Manufactured from Rockwell B40 hardness steel, it maintains dimensional integrity under repeated stress cycles, while the precise 0.281" ID and 0.5" OD ensure optimal load distribution without misalignment. Its corrosion-resistant properties make it suitable for outdoor equipment and manufacturing plants, reducing maintenance downtime and replacement costs.
Specification Summary & Compliance
This washer meets standard inch-system dimensional tolerances with an inner diameter of 0.281", outer diameter of 0.5", thickness range of 0.056-0.071", and clipped width of 0.45". It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for global industrial use.
