Frequently asked questions
Does the stainless steel construction offer durability?
Yes, being made from high-quality stainless steel, these washers provide excellent corrosion resistance. This ensures they maintain their integrity and locking functionality over time, even in challenging shop environments.
Will these effectively prevent hardware loosening?
Absolutely. The external tooth design is specifically engineered to bite into the mating surface. This creates necessary friction that helps secure your bolt and nut assemblies, significantly minimizing the risk of loosening due to vibration or movement.
Is this #4 size compatible with standard applications?
Yes. The washers are precisely manufactured to #4 size specifications. They are intended for use in general shop repair, maintenance, or assembly processes where #4 hardware is required.

Each package includes 50 individual washers. This bulk quantity is designed to be convenient for general maintenance and repair tasks, ensuring you have enough spares on hand for multiple projects.
Are these suitable for general equipment repair?
Yes, these are classified as general shop aids. They are ideal for securing components during maintenance, assembly, or repair processes across a wide variety of equipment types.

What is the best way to install these?
For optimal results, these washers should be used in conjunction with matching #4 bolt and nut assemblies. Ensure the teeth are oriented toward the surface you wish to lock for maximum grip and vibration resistance.
Are these washers designed for vibration-heavy environments?
Precisely. The external teeth are specifically engineered to provide enhanced locking capabilities, making them an excellent choice for securing components in equipment where vibration is a primary concern.
Why choose stainless steel for these washers?
