the spring characteristics of very long bolts. An auxiliary spring element, such as helical spring lock washer, is a very effective alternative. Tests run by Lawrence Technological University have shown that the typical helical spring lock washer exhibits a spring rate after flattening which is approximately 70% more effective than a flat

This paper is on spring washers. Springs washers have three basic types: Belleville, curved or cylindrically curved, and wave [2-3]. Belleville washers have truncated cone or spherical shapes and are also called as conical or cupped spring washers. Belleville washers provide a small deflection range and have a high load bearing

Conical spring washers as specified in the present standard are designed for use with bolt/nut assembly involving bolts of property classes 8.8 to 10.9. The efficacy of spring washers is greatly reduced if they are used together with fasteners of property classes less than 8.8, due to indentation.

Increased washer production capacity and enhanced technology allow Boker's quality non-standard washers to be manufactured quickly, well into the millions. 2 New Tools Continually Added!
