Same temperature characteristics as standard bolt / nut. • Reusable – in addition, Nord-Lock washers do not affect the reusability of fasteners.

The TREP ®spring washer consists of 3 or 4 interdependent smooth tapered spring washers assembled with a metal insert. These results also explain why the use of TREP ® safety spring washers is recommended in French standard NFF 61-021 to compensate for thermal expansion. [Ref.

Dominique Borrelly took the reins of the company in 1990 and has continued its growth through a policy of continual innovation. Numerous investments in human and technical resources ensure

When carbon steel helical spring washers are required for galvanizing, this must be indicated on the order or inquiry. ASME standards call for such washers to be coiled to limits 0.020" in excess of conventional standards. Galvanizing is not recommended for washers under a

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

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

washers/lock washers are available in two versions: The standard Metric SCHNORR® rib spring safety washers/lock washers type "S" which is available for screws of sizes between M1.6 to M30 and of the property classes up to 8.8. For screws of property classes 8.8 and 10.9 where higher pretension forces might be necessary, the reinforced

This spring rate is usually very high, allowing the spring to produce very large loads in a very small space. Belleville springs can be stacked in a variety of ways (Figure 2). A.
