Professional Applications & Engineering Value

This black-oxide steel sleeve washer is engineered to address common industrial challenges such as fastener corrosion, misalignment, and vibration-induced failure. The black-oxide surface treatment provides a protective layer that resists rust and oxidation, making it ideal for humid or outdoor environments in machinery, automotive, and construction sectors. Its sleeve design enhances stability by guiding the No. 10 screw accurately, distributing loads evenly across surfaces to prevent cracking or indentation. With a Rockwell C35 hardness, it maintains structural integrity under repeated stress, reducing maintenance needs. Suitable for heavy-duty applications like equipment frames and electrical enclosures, this washer ensures long-term reliability while meeting stringent RoHS and REACH compliance for global supply chains.
