Flat Plain Washers/ Plain Washers (Steel)
Plain Washers are also known as Flat washers and their work is to distribute the fastener’s load while reducing heat and friction during the tightening process. They are typically designed to spread the loan and protect the respective surface from damage. They can also be used as spacers, as is common in industrial and domestic applications. The most common type of washer is a plain washer, also known as a flat washer. Looseness can result when the bearing surface sinks under the surface pressure, so using a flat washer to reduce the surface pressure is very effective.

Hardened & Tempered Steel Washers
Hardened washers are made physically stronger through hardening or carburizing, but are generally smaller in size than your standard washer. Hardened flat washers are designed with extra strength and can be used with Grade 8 bolts and other heattreated fasteners.
Application:
- Washers are for assembly around a bolt or screw, between the bearing surface of the fastener and the part to which it is attached. items
Technical Specification:
Spring Washers
Spring washers, have axial flexibility and are used to prevent fastening or loosening due to vibrations. This type of washer can be used, that supposed prevent losing and spring action and edge that digs into the screw-on the reverse. Spring washers add tension to a fastener assembly and are used to absorb shock or vibrations.
Application:
- The primary purpose of spring washers is to provide tension and preload in a joint assembly. This helps to maintain clamping force and prevent loosening or loss of tension due to vibration, thermal cycling, or other factors
