We propose weight reduction using titanium screws! Due to its density being about 60% that of steel, we achieve a weight reduction of approximately 40%. Titanium products are widely used in aerospace, medical devices, military supplies, chemical industry, marine equipment, and dental instruments due to their high strength, high corrosion resistance, high-temperature resistance, and good compatibility with the human body. *For product details, please refer to the catalog available for download below under "PDF Download."

The "stainless steel hex socket bolt" is standardized for use in drones, semiconductor manufacturing equipment, medical devices, small robots, and other equipment, offering rust-resistant hex socket bolts suitable for precision machinery, making it a mass production-friendly forged product. We have also standardized ultra-fine sizes of hex socket bolts made from stainless steel, which is difficult to process. There are very small products such as M1.0, which can be used not only as fastening components but also as accents to give a mechanical appearance to small drones and small robots. *For product details and specifications, please refer to the "PDF Download" below.

"RaviLock" is a waterproof screw that has passed the IPX8 test. In our in-house testing, it prevents water ingress equivalent to a depth of 10 meters. The seat features a multi-groove structure that creates a maze-like design, dispersing external pressure. As a result, it demonstrates waterproof performance without the need for O-rings. Additionally, since the waterproof support is provided solely by the screw body, cost reduction is possible. 【Features】 ○ Patented ○ Achieves the same function as a gasket with multi-groove processing ○ Provides waterproof effect with double air packing ○ Utilizes the labyrinth effect ○ Two types of applications: air packing effect and labyrinth effect *For more details, please refer to the PDF document or feel free to contact us.
