Contact Disc Springs

Contact Belleville disc springs combine two essential features for improved bolt connections—their conical shape provides reactive force and high elasticity of spring return to compensate for developed looseness and loss of bolt tension due to thermal expansion and contraction. Additionally, this spring's hardened, serrated profile grips the bolt or nut's lower surface to prevent the loss of tension that generally occurs during extreme vibration or shock.

Contact Disc Springs Manufacturing & Configurations

Contact Disc Springs come in sizes that correspond to a wide range of screw head sizes, including hex head socket screws. They can also be used in assemblies. The “Narrow” Contact Disc Springs are designed for use in confined space like under a socket head screw. “Wide” Contact Disc Springs are ideal for oversized holes in sheet metal applications, making use of a wide bearing surface, and “Regular” contact disc springs are recommended for other general applications. All Contact Disc Springs are made of selected high-quality carbon spring steel unless otherwise requested.
