Useful Rolling Nipple Screw

A pipe thread with strong joint strength! Achieves excellent earthquake resistance, pressure resistance, and durability!

The "Rolling Nipple" is a pipe thread that has a strong connection strength with fittings and excels in earthquake resistance, pressure resistance, and durability. Traditionally, pipe threads used in piping fittings were mainly produced through cutting processes, but there were various performance issues due to the reduction of effective pipe thickness from cutting, as well as inconsistencies in thread precision and surface smoothness. Our product achieves a high-precision and smooth thread surface through rolling threads, improving the adhesion between male and female threads. It resolves the issues associated with cutting threads. 【Features】 ■ Earthquake resistance ■ Pressure resistance ■ Durability ■ Sealing performance *For more details, please refer to the catalog or feel free to contact us.

Please feel free to consult us about anything related to "screws" or "metal processing" [Q&A materials available].

Regarding "screws" and "metal processed parts" that excel in high conductivity, non-magnetism, high durability, high precision, and lightweight properties, suitable for EV and autonomous driving-related products.

When procuring items like "screws" or "metal processed parts," it can be too mundane and detailed for the person in charge to invest time and effort, leading to limited consultation options. Additionally, regarding aspects such as [price], [delivery time], [quality], [production lot], and [shape], it is often the case that compromises are made, even if the result is not truly what is desired. In such cases, please do not hesitate to consult Tokai Parts Industry! Our greatest strength as a manufacturer is our ability to "create." Instead of searching for existing parts, we can "build from scratch," allowing us to make detailed proposals regarding materials and shapes from the development stage. We offer flexible responses to specification changes for fluid products, small lot production, delivery times, quality assurance, and a one-stop service that handles everything from the entrance to the exit, strongly supporting our clients. For over 70 years since our founding, we have continued to be chosen by many clients. Why is our company able to do such things? This time, we have summarized the secrets in a Q&A format! *We will also be exhibiting at the Mechanical Elements Technology Exhibition from June 19 (Wed) to 21 (Fri) [Booth No. E43-44]! *For more details, please download the PDF and check the Q&A.
