Short Description:

FLAT WASHERS – GOOD PROTECTOR TO SURFACE BEING FIXED Flat washer, also know as plain washer, is a thin, flat annulus or ring, in both zinc plated steel and stainless steel. With a larger bearing surface, it is used under a bolt or nut to distribute the load of a screwed fastening as well as protect the surface being fixed. Additionally, flat washers prevent loosening under vibration as well as avoid galvanic corrosion if you use steel bolts on an aluminum surface. Dimension of a flat w...

    FLAT WASHERS – GOOD PROTECTOR TO SURFACE BEING FIXED

    Flat washer, also know as plain washer, is a thin, flat annulus or ring, in both zinc plated steel and stainless steel. With a larger bearing surface, it is used under a bolt or nut to distribute the load of a screwed fastening as well as protect the surface being fixed. Additionally, flat washers prevent loosening under vibration as well as avoid galvanic corrosion if you use steel bolts on an aluminum surface.

    Dimension of a flat washer

    You may never think about flat washers until you need them, but they are indispensible in a host of applications and available in hundreds of different shapes, sizes to suit different projects. Below are the most common types offered by us, a professional manufacturer of metal washer .

    Details:

    Material: steel in grade 4.8, 8.8, 10.9 and 12.9; stainless steel 304 and 316.
    Finish: plain, zinc plated (clear, yellow or black).
    Inside diameter: M6 to M54.
    Thickness: Any custom thickness is available.
    Package: plastic bags and paper carton.
    Standard flat washer 
    As the most common type, a standard flat washer features two flat surfaces that make it efficient to distribute fastening forces, reduce vibration, friction as well as heat generated during installation. Available in GB, USS, SAE types for all purpose low strength fastening.
    Heavy duty flat washer 
    Made of stronger and thicker material – 45H carbon steel, heavy duty flat washers allow for extra strength and better load distribution properties. Diverse applications include general industries, machinery, powder transmission and various heavy duty bearing uses.
    Fender washer 
    Wither larger outer diameter in proportion to the central hole, fender washers provide larger working areas for more efficient force distribution. They are incredibly well suited for plumbing, electrical industry and sheet metal applications such as fixing signs, panels and drywall.
    Dock washer 
    A dock washer refers to a washer in larger outside diameter and thickness compared with the fender washers in the same size. Normally, they are used in dock, wood construction and various heavy duty load bearing applications.

    SPLIT WASHER – SOLUTION TO LOOSENING PREVENTION

    Split washers, also known as split lock washers or spring lock washers, feature a single cut that extending from the outside diameter to the center hole. The two ends are misaligned and exert the washer to create a special helical shape – like a donut. And it is this misalignment allows for a positive locking section – creating more friction for better resistance to rotation & loosening.

    rt
    Split washers in a variety of diameters and thicknesses are available.

    Split washers are extensively used where loosening from vibration and corrosion are primary concerns. Meanwhile, they match well with socket head cap screws and ideal for areas with installation space limitations.

    Feature:

    Made from quality spring steel that strongly resists to compression.
    Allow for greater bolt tensioning for a tighter joint.
    Thicker than normal flat washers to sustain overall locking effectiveness.
    Zinc plated for added corrosion resistance and longer lifespan.
    Prevent loosening by taking up compensates caused by slight friction or vibration.
    Excellent resistance against both high and low temperature.
    Durable structure with high hardness.
