Waterproof screws for precision machinery "Ravilock"

It can demonstrate excellent waterproof performance and reduce costs without using O-rings.

"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.

A new proposal for those looking for a new grip with anti-loosening treatment【Anti-loosening】.

A new proposal for those looking for a new grip with anti-loosening treatment【Anti-loosening】.

We propose the Japanese-made grip with a looseness prevention treatment called 'NEO.' Since we use Japanese-made chemicals, there are no issues with the supply side.

The general type of locking grip applies microcapsules to the screw section, similar to the anti-loosening treatment, to prevent loosening of the screws after fastening. (Locking type) *We generally do not offer application only. We will provide proposals that include screw processing. Our company maintains a high quality and flexible response system by increasing the processes we perform in-house, such as in-house manufacturing of various machines involved in production. We also respond quickly to customization requests. 【Features】 ■ Microcapsules applied to the screw section ■ Prevents loosening of screws after fastening ■ Locking type ■ Custom colors available ■ Environmentally friendly (water-based) *For more details, please feel free to contact us.

Vibration-resistant screw "UHSCREW"

Vibration-resistant screw "UHSCREW"

By increasing the axial force in particular, it exhibits a force that is difficult to loosen! It has a high restraining force against rotational loosening.

"UHSCREW" is a vibration-resistant screw designed to be fastened with greater axial force by changing the shape of the thread profile, making it less prone to loosening. The tightening characteristics exhibit excellent fastening strength due to the "elastic strain energy" stored in the threads from elastic deformation, resulting in superior vibration resistance. The contact surface between the male and female threads during fastening is positioned further away from the axis compared to standard small screws, which increases the torque arm of the rotational friction, thereby enhancing the restraining force against rotational loosening. 【Features】 ■ Less prone to loosening ■ Designed to be fastened with greater axial force by changing the shape of the thread profile ■ Exhibits excellent fastening strength with superior vibration resistance ■ The contact surface between the male and female threads during fastening is positioned further away from the axis compared to standard small screws, resulting in a longer torque arm of the rotational friction ■ Higher restraining force against rotational loosening *For more details, please refer to the PDF document or feel free to contact us.
