The main reasons for using 304 Stainless Steel Flat Washers include –

  •   To spread or distribute the load of the threaded fastener evenly.
  •   To reduce vibrations and wear in the fastener.
  •   washer aisi 304 acts as a spacer, a preload indicating device, a locking device.
  •   The washer sus304 can also act as a spring.

Besides these features, the 304 grade is known to have good weldable and formability. Hence, the Type 304 Washer can be manufactured into any desired shape. Washers are typically manufactured in the shape of a disc and have two diameters on account of the inner hole and the outer circumference. While disc shaped washers are pre-dominantly used in various industries, other shapes like square, wave, split, star shaped etc.

A basic metal or plain flat washer ss 304 also known as a ring washer is , often used to spread the load of a screwed fastening. This ss 304 flat washer may also be used in applications where the hole is of a large diameter as opposed to the fixing nut.A star washer 304 is manufactured with serrations that extend radially inward or outward. These serrations bite into the bearing surface. The star washer is more effective when used with a soft substrate like aluminium or plastic. In fact, it tends to work effectively as a lock washer because it can resist rotation in comparison to a plain 304 stainless washer used on a hard surface.

ss 304 spring washer also known as helical or locking washers are used in those applications where the fastener loosening or fastening is required to be prevented during the occurrence of vibrations.
