Reliable hold and secure tightening. Stability that withstands vibrations with a washer featuring claws.
We would like to introduce a case study on the processing of the "Washer with Claws" from Masao Press Co., Ltd. The washer with claws is a special washer designed to prevent bolts and nuts from loosening. Unlike regular washers, it has protrusions (claws) on the inside. These claws help the washer to be firmly pressed against the surface, preventing loosening due to rotation or vibration. It is mainly used in machinery, automotive parts, and construction, playing an important role in enhancing safety and durability. Our company has received high praise from the infrastructure equipment industry and is adopted by major infrastructure equipment companies. 【Case Overview】 ■ Product Name: Washer with Claws ■ Material Details: SPCC ■ Size: t1.6 φ130×φ80 ■ Processing Details: Laser + Bending + Plating * We can accommodate various materials and sizes. Additionally, if the edges of the processed parts are a concern, barrel polishing is also available. * For more details, please refer to the materials. Feel free to contact us!

Company information
Masao Press is a comprehensive press processing manufacturer that handles everything from "mold design and manufacturing" to "prototype to mass production pressing" and "secondary processing." Aiming to be a "metal press processing manufacturer that connects reliable manufacturing to the next generation," we have been engaged in metal press processing and sheet metal processing since our establishment in 1979, handling a wide variety of materials and plate thicknesses. We can accommodate everything from metal design to prototyping, processing, small-lot mass production, assembly, custom products, non-standard products, and secondary processing. Since we possess both mold press and sheet metal equipment technologies, we can propose suitable processing methods based on the shape and size of the parts, production lot, and delivery time, responding to requests regarding the presence of molds and labor reduction according to production lot sizes. With over 40 years of experience, we have accumulated extensive know-how and processing conditions for a wide range of processing materials, plate thicknesses, and heat treatments for secondary processing. By combining the analog techniques of skilled craftsmanship, honed through years of experience, with the efficiency and sophistication of digital technologies using 3D CAD/CAM, we deliver high-quality and high-precision products.
