Description:
Materials - These internal tooth starlock washers are made of 65Mn materials, which have high hardness and do not deform. They are suitable for indoor, outdoor, or humid environments, with fine craftsmanship, beautiful appearance, good corrosion resistance, long-lasting strength, and durability.
Design - Lock washers apply spring force between the fastener head and base, causing the washer to adhere tightly to the base and the bolt to adhere tightly to the nut, resulting in more friction and rotational resistance. Provide a locking effect to ensure tight fit and slip resistance.
Easy to Operate - Our locking fasteners are very convenient to use. You just need to prepare the appropriate screws, then insert the washers into the screws, and tighten the nuts to complete the assembly. Even beginners can operate seamlessly.
Widely Applicable - Our locking washers are suitable for threaded and bolted connections of various household and commercial appliances, and automotive and marine power supplies. Widely used in mechanical equipment and industrial production for shock absorption and insulation. These multifunctional fasteners provide stable and non-rotating gasket placement for various DIY tasks and electrical repair projects.
