Product Description
GN6339 Heavy Duty Washer, Low Type, Steel
The influence of a washer on the quality of the screwed connection is very often underestimated. With these washers, high quality preloaded screwed connections can be established. A high static clamping force can be reached avoiding loss of tension.
At a specified preloaded clamping force it is often possible to use thinner bolts. This can result in a better ratio between clamping distance and bolt diameter to minimise the danger of failure.
The case hardened smooth bolt head/screw contact face leads to a lower and more constant friction co-efficient even when continuous clamping and releasing operations are required.
Washers GN 6339 are only suitable for machine construction bolts of classes 8.8/10.9 /12.9.
