Angled-Edge Washers for Toggle Clamp Holding Screws
Use on clamps with open arms to keep the holding screw in place.
302 stainless steel washers provide better corrosion resistance than steel washers.

Push-On External Retaining Rings
B
No groove required—press these rings onto the end of a shaft. Use them on unhardened shafts that are softer than the push ring. The ring bites into the metal to form an interference grip. Styles A, B, and C have teeth that dig into the shaft material, so expect minor scratching. Use a push nut installation tool (sold separately) to install rings, or install them manually.

Corrosion-Resistant Belleville Disc Springs
Made of stainless steel, these springs are more corrosion resistant than steel springs. Use them on shafts, bolts, and the ends of valves to maintain tension and separate components. Unlike Belleville washers, they return to their original height once the load is removed.
Deflection is the distance a spring compresses under load. Flat load is the load at which the spring is completely compressed.
Springs may be stacked to increase working load and deflection. In a nested stack, working load is multiplied by the number of springs used, while deflection remains unchanged. In an inverted stack, deflection is multiplied by the number of springs used, while the working load remains unchanged. In a nested and inverted stack, both load and deflection are increased.

Corrosion-Resistant Wave Disc Springs
Made of stainless steel, these springs are more corrosion resistant than steel wave disc springs. With multiple contact points to distribute the load, they provide more balanced support than curved and notched disc springs. They're also known as wave spring washers.
