Spherical Split Lock Washer - Steel DIN 74361-C
DIN 74361-C spherical lock washers are engineered to provide secure and reliable fastening solutions in demanding applications. The washers are designed with a conical or spherical shape and a split section to function as a spring, creating continuous tension and a locking force between the bearing surface (such as a screw head) and the mating material when compressed.
This mechanical grip and inherent spring tension are crucial for preventing the fastener assembly from loosening due to vibration or dynamic loads, making them significantly more effective than standard flat washers in dynamic environments. Also referred to as a countersunk spring lock washer.
Material: Spring Steel
Constructed from durable spring steel material, chosen for its high tensile strength and resilience. Spring steel's ability to undergo significant deflection under load and return to its original shape ensures consistent clamping force over time, even with thermal expansion or contraction in the joint.
High-quality zinc-plated finish, a cost-effective solution that provides excellent protection against rust and oxidation. This protective zinc layer acts as a sacrificial coating, corroding before the underlying steel base metal, which dramatically extends the lifespan of the washer and maintains the integrity of the fastened connection, even in humid or moist environments.
Use
Highly versatile for use across numerous industries and products. Essential components in heavy-duty applications such as automotive assemblies (disc wheel and engine components), construction machinery, and industrial equipment where vibration and shock are prevalent.
