A hook washer is a type of washer with a protruding hook or tab designed to prevent rotation or loosening of bolts and nuts by locking into a slot or groove in the assembly.
Yes, hook washers can be customized in size, material, thickness, and tab design to meet specific assembly requirements and ensure secure fastening.
They are commonly used in mechanical assemblies, automotive components, electrical equipment, and industrial machinery, especially in applications with vibration or rotational forces.
Place the hook washer between the nut (or bolt head) and the surface to be fastened, ensuring the hook or tab engages with the corresponding slot, groove, or hole to prevent rotation.
Hook washers are typically made from carbon steel, stainless steel, or alloy steel, providing strength, corrosion resistance, and durability for various applications.
The main function is to secure fasteners against vibration or torque. The hook or tab locks into place, preventing the nut or bolt from turning unintentionally.
Make it easy for customers to make shafts and apply them to more fields.
