    Characteristics of Eastech Nusantara's Washer

    Coated Body

    Coated washers provide an extra protection for corrosion resistance, long lasting material lifespan, and ensures a more uniform clamping force.

    Consistent Clamping Force

    The clamping force will be applied evenly and reduces the risk of over-tightening and preventing loosening during installation.

    Enchanced Stability

    Flat washers improve the stability and reliability of connections, when dealing with vibration or thermal expansion.

    Even Load Distribution

    Washers increase the bearing area of a fastener, which reduces the pressure exerted on the material that being fastened.

    Surface Protector

    Flat washers act as a barrier between fastener and the surface, preventing damage from indentation, scratching, and abrasion.

    Wide Range of Applications

    Our washers are usually used in different applications such as construction, general fastening, automotive, heavy machinery and equipment.
