"UltraSert UDIV" is a standard insert nut with excellent holding power. The material is brass (iron, stainless steel, aluminum), and the screw management standard is JIS Grade 2. If you encounter issues with the surface of molded products sinking in tapered holes when designed with "UltraSert II," please consider this option. [Features] ■ Usage method: Heat press fitting ■ Compatible resin: Thermoplastic ■ Material: Brass (iron, stainless steel, aluminum) ■ Screw management standard: JIS Grade 2 *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Dodge Insert SD" that we handle. By pushing down the expansion plate to the specified position, the knurled part expands and exerts force. Therefore, it can be used even when the boss thickness is relatively thin. Additionally, since it is an expansion method, it can accommodate a wide range of applications regardless of the material of the counterpart. 【Features】 ■ Usage method: Expansion method ■ Compatible resins: Thermosetting and thermoplastic ■ Material: Brass ■ Screw management standard: JIS Class 2 (excluding the slotted part) *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Dodge Insert FD" that we handle. By pushing down the expansion plate to the specified position, the knurled part expands and exerts force. If the hole diameter of the counterpart fastening component is large, the flange helps prevent issues such as jack-up troubles. 【Features】 ■ Usage method: Expansion type ■ Compatible resins: Thermosetting and thermoplastic ■ Material: Brass ■ Screw management standard: JIS Grade 2 (excluding the slotted part) *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Long Nut" that we handle. It can be used for various purposes such as spacers, collars, and embedding in resin. We also manufacture types with grooves and round nuts. Please feel free to contact us when you need them. 【Features】 ■Usage: Spacers, etc. ■Material: Brass (Stainless Steel) ■Thread Management Standard: JIS Grade 2 *For more details, please refer to the PDF document or feel free to contact us.

This product is an insert nut used by inserting it into molds during the molding process. We offer a wide range of options, including "XZE (grooved double-sided type)," "SXE (grooved single-sided type)," and "XYE (grooved bag type)." Additionally, the length of the effective screw area will be approximately 3mm shorter than the total length, but as the screw size increases, the length of the effective screw area will decrease, so please consult with us. 【Features】 ■Usage: During molding ■Compatible resins: Thermosetting and thermoplastic ■Material: Brass ■Screw management standard: JIS Class 2 *For more details, please refer to the PDF document or feel free to contact us.

The "Insert Bush WCH" is designed for forming processes that roll and shape sheet materials, resulting in minimal material loss and significant cost reductions compared to machined products. By applying a unique dimple shape to the outer circumference of the bush, it demonstrates exceptional effectiveness in preventing free rotation and disengagement after resin molding. The new type of dimple shape improves the pulling force by 1.7 times compared to conventional designs, allowing for the proposal of products that are more resistant to disengagement. 【Features】 ■ Significant cost reduction by replacing machined products with rolled materials ■ Prevention of free rotation and disengagement after molding through a unique dimple shape ■ Capable of processing not only circular but also oval bushes ■ Unique seam bonding technology that effectively prevents resin leakage *For more details, please refer to the PDF document or feel free to contact us.

An "insert nut" is a fitting used to attach screws to resin materials such as plastic. By using insert nuts, the strength of screw holes is improved, preventing cracking in the resin and enabling a high degree of design flexibility. Tokai Metal Industry Co., Ltd. provides high-quality insert nuts through a rigorous quality control system and has received high praise from industries that require high reliability, such as the automotive sector. In addition to a variety of standard shapes, we can also create custom products tailored to customer requests. We can conduct strength tests regarding compatibility with resin materials as well. We are also available to assist with any other concerns or inquiries. For more details, please refer to the PDF materials or feel free to contact us.

The "Alu-Arma(R) Nut" is a nut made from aluminum alloy. It is treated with a special hard anodizing based on Alu-Arma(R) on the surface to ensure electrical insulation and prevent the occurrence of galvanic corrosion. When molded into CFRTP containing 40% carbon fiber and evaluated using the JIS saltwater alternating immersion method, it maintains corrosion resistance for 3,000 hours. 【Features of the Alu-Arma(R) Nut】 ■ The Alu-Arma(R) treatment strongly prevents the occurrence of galvanic corrosion. ■ Made from aluminum alloy, it allows for weight reduction of the nut itself. ■ The fastening with CFRP material is expected to provide significant synergy effects for weight reduction. ■ Its shape, which allows for easy flow of carbon fibers, provides high pull-out strength in CFRTP. ■ Reducing costs for galvanic corrosion countermeasures also lowers the overall manufacturing costs. ■ Two basic shapes are available to choose from depending on the lot. *For more details, please feel free to contact us.
