Disc Springs (Washers)

Inch and Metric Pouce et Métrique

for locking bolts, screws and nuts Rondelles à ressort (Belleville) High Quality Carbon Spring Steel (oil Finish) CONTACT Disc Springs combine two important features for improved bolt connections. Their conical shape provides a reactive force and a high elasticity of spring return to compensate for developed looseness, loss of bolt tension due to applied surface deterioration, or movement due to thermal expansion and contraction. The hardened, serrated profile “grips” the

lower surface of the bolt or nut to prevent the loss of tension that normally occurs during extreme vibration or severe shock.
