RPI RPH176 No. 10 Internal Tooth Washer

Yes, these washers are constructed from high-quality stainless steel. This material choice is intentional, offering enhanced corrosion resistance and superior durability compared to standard washers, ensuring they maintain their structural integrity over time.

Absolutely. The internal tooth design is engineered specifically for this purpose. The teeth provide a positive locking action that grips the mating surface, significantly resisting loosening caused by operational stress, torque changes, or equipment vibration.

Yes, these are precision-manufactured to a #10 nominal size. They are designed to fit perfectly onto standard #10 diameter shafts or bolts, ensuring a secure and reliable fit for your assembly needs.

Yes, each purchase includes a 50-count package. This ensures you have an adequate supply on hand for multiple uses, equipment maintenance, or larger hardware projects without needing to worry about running short.

Yes, these items are Factory New. This guarantees that you are receiving unused, current-stock quality components that meet RPI’s high standards for industrial and mechanical applications.

They are ideal for general shop aids and hardware assemblies. Specifically, they are recommended for any application subject to vibration—where a standard flat washer might be insufficient—to maintain long-term joint integrity.

Certainly. While these are available as a standalone 50-count pack, they are also a component of the RPI Lockwasher Kit (Part #RPK413). If you are doing a larger overhaul or require a variety of locking hardware, the full kit is a great solution.

Yes, the RPI RPH176 is classified as an industrial-grade component. Designed for reliable performance in demanding mechanical environments, these washers provide the durability required for professional shop use.

Yes, installation is straightforward. Because they are designed for standard #10 fasteners, they can be installed easily using your existing standard tools. No specialized equipment is required to achieve a secure locking connection.

While a flat washer primarily distributes load, an internal tooth lock washer is engineered for security. The sharp, radially extending teeth engage with the mating surface, creating a mechanical lock that prevents the fastener from backing out due to cyclic loading or operational stress.
