          Washers
          Washers are primarily used as a seat to distribute load, but they may also provide spring tension, span oversize holes, insulate, seal, or provide electrical connection. Various kinds include flat, conical, and helical-spring washers, tooth or ribbed lock washers, and special-purpose washers.
          The washer size to be used with a particular screw size is determined by the first number in the screw size.

          Helical-spring washers
          for example: spring washers ANSI l-9(table-1),DIN 127-B(table-2),B.S.(table-3),etc.

          Flat washers
          Also known as plain washers, provide a bearing surface for a nut or screw head, cover large clearance holes, and distribute fastener loads over a large area, particularly on soft materials. This, in turn, reduces contact stresses and can thus reduce relaxation.Our offer list:

          Conical washers
          These are used with screws to add spring take-up to screw elongation. Type L conical washers are designed for use with unhardened screws. Type H series is for hardened screws. Conical washers are designed to flatten at approximately one-half the ultimate load of the screw.
