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.


Steel ST, 42CrMoS4V, 1.7227, case hardened to tensile strength Rm = 1220 - 1400 N/mm. Fine machined and fine ground.
