Nitto Seiko Releases Cup Bolts with High Locking Effect

2024-05-24
Nitto Seiko has released a type of Cup Bolt, which is a flange-type locking bolt that can replace bolts incorporating spring washers and flat washers. This new product is currently patent pending.
Conventional locking bolts generally use a combination of a spring washer and a plain washer. The new Cup Bolt has a flange integrally molded on the head with a tapered undercut section extending from the neck to the outer periphery, and a continuous undercut section located at the outermost periphery. It has a cup shape consisting of a flat part. When fastened, this part elastically deforms and acts like a spring washer, so you can get a strong locking effect without using a spring washer or flat washer. Additionally, by reducing the number of parts, the Cup Bolt achieves a weight reduction of approximately 18% compared to conventional models.
