We recommend the "Large Diameter Hexagon Socket Bolt Strength Class 12.9" for molds and industrial machinery. Traditionally, for domestically produced large diameter hexagon socket bolts exceeding M20, those of strength class 10.9 were available in the market. Therefore, when bolts of strength class 12.9 were absolutely necessary, we had to resort to custom manufacturing, which increased costs. However, thanks to the Taiwanese screw manufacturer YFS, we can now maintain a constant stock of hexagon socket bolts of strength class 12.9 with nominal diameters M22, M24, and M30 in Japan, greatly improving availability. We encourage you to consider this option. 【Product Lineup】 ■M22 ■M24 ■M30 *For more details, please refer to the PDF document or feel free to contact us.

Our company provides solutions for your screw-related issues through "screw coating and surface treatment." Iron screws are prone to rust in their natural state, so they are often used with surface treatments applied, which can also serve decorative purposes. Additionally, while many screws with various surface treatments are already available on the market, we can perform surface treatments even if they are not commercially available. Please feel free to contact us. 【Features】 ■ Supports surface treatments such as electroplating, electroless plating, hot-dip galvanizing, chemical conversion treatment, heat treatment, painting, and coating. ■ Can substitute conventional plating with environmentally friendly options (e.g., alternative to unichrome: electro-galvanized zinc plating with trivalent chromium chromate treatment). ■ Supports decorative plating such as chrome plating, tin-cobalt plating, gold plating, and substitute gold plating. *For more details, please refer to the PDF document or feel free to contact us.

"Sea Horse Lock" is a locking treatment that involves applying a locking liquid to screws. Since it is delivered after application, there is no labor or cost associated with manual work, allowing for immediate fastening. Because it can be uniformly applied by machine, it prevents loosening accidents caused by uneven application or missed spots, enhancing safety. Additionally, since it is custom-made, specifications for color and range can be accommodated. There are two types: the "Resistance Type," which exhibits high locking effectiveness by mixing resin and other materials with the locking liquid to create resistance with the screw part, and the "Adhesion Type," which generates an adhesive effect through the chemical reaction between microcapsules and hardeners. [Features] ■ Delivered after application, allowing for immediate fastening ■ Uniform application by machine ■ Custom-made with specifications for color and range, making management easy ■ Two types: "Resistance Type" and "Adhesion Type" *For more details, please refer to the PDF document or feel free to contact us.

The anti-loosening treatment "Seahorse Lock" can be broadly divided into two types: "Resistance Type" and "Adhesion Type." The "Resistance Type" primarily mixes resins and other materials into the anti-loosening liquid, demonstrating excellent elasticity and achieving a high anti-loosening effect through resistance with the screw part. The "Adhesion Type" contains microcapsules within the anti-loosening liquid, which rupture under the pressure of tightening the screw, triggering a chemical reaction with the hardening agent outside the microcapsule, resulting in an adhesive effect. As a result, the anti-loosening agent pre-applied to the screw firmly adheres to the counterpart through the adhesive, effectively preventing loosening. 【Features】 ■ Resistance Type - Suitable for situations where a strong adhesive effect may have adverse effects or for preventing the loosening of adjustment screws. ■ Adhesion Type - Adhesion effect is stable for 3 days. - Excellent sealing properties. *For more details, please refer to the PDF document or feel free to contact us.

This document introduces the "Screw Conversion Adapter Ver.5." It has been updated to the revised version Ver.5. Using screws with different standards can lead to issues where the screws do not fit due to differences in standards or pitch. Forcing the screws can damage the threads. Although screws with different standards may fit together in some combinations, there can be significant play, which may cause the screws to loosen or fall out during use, posing a serious danger. Such usage must be avoided. Here, we also explain the reasons why a screw conversion adapter is necessary. [Contents] ■ Reasons for needing a screw conversion adapter ■ Screw conversion adapter (metric coarse thread) male-to-male type standard specification ■ Screw conversion adapter (metric coarse thread) male-to-female type A standard specification ■ Screw conversion adapter (metric coarse thread) male-to-female type B standard specification ■ Screw conversion adapter (metric coarse thread) female-to-female type standard specification *For more details, please refer to the PDF document or feel free to contact us.
