Unlocking reliable fastening solutions with Officine Riva’s palnuts

Join us for an insightful exploration of one of Officine Riva's top products, its palnuts. As we venture into the realm of reliable fastening solutions, we'll unravel the exceptional features and benefits that make these fasteners stand out in the industry.

Officine Riva's palnuts, also known as self-locking counter nuts, excel in various applications, from the automotive industry to the fields of construction and infrastructure. These nuts are manufactured using carbon steel strip for springs according to UNI EN ISO 10132, ensuring exceptional cold formability. With a hardness range of HV 350-425, they can be annealed and hardened for optimal performance.

Precision is at the core of Officine Riva’s palnut design, adhering to medium precision grade dimensional tolerances as specified by UNI 5307. They boast smooth surfaces without any burrs on both internal and external edges. The raw and oiled surface finish adds an extra layer of corrosion protection.

One standout feature of Officine Riva’s palnuts is their efficient locking mechanism. During the efficiency test, the locknut is initially hand-tightened onto the nut and then firmly secured with a wrench at a 45° angle. The nut is then slightly unscrewed, ensuring that the locknut is not dragged along in the rotation. This process lightly loosens the nut while ensuring the locknut remains stationary. Even with a 90° rotation, the locknut remains tight, showcasing its reliability and resistance to loosening. Rigorous testing guarantees that the locknuts exhibit no visible cracks, initial fractures, or significant deformations after the test.

Palnuts come in key width values of 17, 19, 22, and 32 mm, aligning with prevailing UNI standards for compatibility and ease of use. These standardized dimensions ensure a reliable fit with various fasteners, promoting proper installation and optimal functionality.

Officine Riva's palnuts are highly customizable, offering additional coatings or surface finishes based on specific requirements.
