• Corrosion-resistant brass construction provides excellent durability in humid or corrosive environments, extending the lifespan of your assemblies.
• Precise dimensional fit with 0.14" inner diameter and 0.375" outer diameter for reliable alignment and secure fastening with No. 4 screws.
• Low-profile design at 0.11" overall height minimizes space requirements while maintaining structural integrity in tight applications.
• Inch system compatibility ensures seamless integration with standard imperial-sized components, reducing installation errors.
• Environmental compliance with RoHS 3 and REACH regulations guarantees safe use in various industries without hazardous substances.
• Enhanced load distribution due to the brass material and countersunk shape, reducing stress on connected materials and preventing damage.

Professional Applications & Engineering Value

This 82° countersunk brass washer is engineered to address common challenges in precision assemblies requiring flush surfaces, such as in electronics, marine hardware, and decorative fixtures. The brass material offers inherent corrosion resistance, making it ideal for environments exposed to moisture or chemicals, while the precise 0.14" ID and 0.375" OD ensure accurate fit with No. 4 screws in the inch system. By providing a smooth, low-profile finish, it eliminates protrusions that could interfere with moving parts or aesthetic designs. The countersunk angle distributes clamping force evenly, reducing the risk of material cracking and improving joint reliability in demanding industrial applications.

Specification Summary & Compliance

This washer features an inner diameter of 0.14", outer diameter of 0.375", and overall height of 0.11", designed for use with No. 4 screws in the inch measurement system. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards. The countersink angle is precision-machined at 82° for consistent performance in flush-mount applications.
