"Sea Horse Lock - Adhesive Type" contains microcapsules within the locking liquid that burst under the pressure of tightening screws, triggering a chemical reaction with the hardener outside the microcapsules, resulting in an adhesive effect. (It takes about 72 hours to fully set.) As a result, the locking agent applied to the screws beforehand firmly adheres to the counterpart with the help of the adhesive, demonstrating an anti-loosening effect. Additionally, not all microcapsules burst, allowing for reusability up to about five times under certain conditions after removal. 【Features】 ■ Color changes are possible for most part numbers (can be used for size identification, etc.) ■ Small screws that are difficult to distinguish can be identified by color coding ■ Usable for M1.0 and above *For more details, please refer to the PDF document or feel free to contact us.

The "Seahorse Lock Resistance Type (Resin Type)" primarily mixes resin and other materials into a locking liquid, demonstrating excellent elasticity and achieving a high locking effect through resistance with the threaded parts. It is suitable for use in areas where strong adhesive effects can be counterproductive, such as plastic products, as well as for adjusting screws and preventing detachment. Additionally, quality control is conducted based on the viscosity of the applied liquid and the application length, allowing for the adjustment of "torque" by regulating the amount of liquid entering the thread valleys and the application length. 【Features】 ■ Quality control is conducted based on the viscosity of the applied liquid and the application length ■ "Torque" is adjusted by regulating the amount of liquid entering the thread valleys and the application length ■ Changes to other colors are possible for most part numbers (can be used for size identification, etc.) ■ Small screws that are difficult to distinguish can be identified by color coding ■ Usable for M1.0 and above *For more details, please refer to the PDF document or feel free to contact us.

"ThreeBond Precoat Bolt Mech Processing" is a processing technology that applies a special treatment to the threaded part using a formulation of microcapsules containing adhesive, giving the screw itself sealing and locking functions. Since the screw itself is equipped with these functions, there is no need for locking agents, sealing agents, or sealing tape. Additionally, there is no risk of forgetting to apply by the operator or variations in application. Furthermore, it demonstrates its effectiveness simply by tightening it like a regular screw, which simplifies the work process. 【Features】 ■ No need for locking agents, sealing agents, or sealing tape ■ No forgetting to apply by the operator or variations in application ■ Sealing and locking effects are achieved just by tightening like a regular screw ■ Work processes can be simplified ■ Total cost reduction is possible from various perspectives *For more details, please refer to the PDF document or feel free to contact us.
