Soft material assistance parts! Protects against buckling and cracking. No matter the shape, please consult us first.

Metal components such as "collars" are used in fastening soft materials like resin to prevent buckling and cracking of the material. For example, inserting a metal collar into a resin hole and fastening it with a bolt helps prevent buckling, sinking, and cracking. Daiichi Kogyo manufactures various types, shapes, and materials of collars, bushes, spacers, and more. We offer a variety of shapes, including cylindrical and flanged types. Please feel free to inquire about any shape you need. As specialists in manufacturing bolts and nuts, we can suggest parts tailored to your requirements. We welcome your consultation. We manufacture and sell products tailored to customer needs in Japan, China, and India. Please feel free to contact us for details regarding materials, delivery times, prices, and more.

From the development stage, the bolt shape has been redesigned for weight reduction!

The "SSOO Bolt" is a high-torque embedded bolt (insert bolt) designed for resin that minimizes deformation and rotation of the resin when tightened with high torque, and is also resistant to pull-out. This bolt is embedded in the resin component with its head, and is secured with a nut. Since the male thread of the bolt stands above the resin, it improves the assembly characteristics of the components. It has been successfully used in the junction boxes and busbars of the traction motor system "e-Axle." Please feel free to contact us if you would like a sample. 【Features】 ■ Minimizes deformation and rotation of the resin when tightened with high torque, and is resistant to pull-out ■ Improved assembly characteristics due to the standing threads of the bolt ■ The special octagonal shape of the head and the serrated grooves on the outer circumference allow the resin to easily engage when embedded ■ Can be embedded either through simultaneous molding or post-insertion via thermal press fitting ■ The shape of the bolt head has been modified for weight reduction *For more details, please refer to the PDF document or feel free to contact us. *Thread sizes range from M4 to M8. Please consult us regarding the length.

The bag nut is the original of JIS Type 3! We offer a variety of product series including iron, stainless steel, titanium, and weld (welding) nuts.

The founder of Daiichi Kogyo Co., Ltd., Akira Suzuki, was the first in Japan to manufacture and sell a bag nut (JIS Type 3 cap nut) with a cap that is press-formed onto a nut. Since its release, it has received positive feedback for being lighter and more affordable compared to traditional cutting types, and it has evolved into a wide variety of forms to suit various applications. You can find it in places close to you, so please remember Daiichi Kogyo when you see it. 【Features】 ○ The head is hollow, making it lightweight and allowing male threads to be inserted to the tip of the cap, preventing exposure of the threaded part. ○ The design is smart and has excellent decorative qualities. ○ It is standardized and can be mass-produced. For more details, please contact us or download the catalog.

Non-magnetic, high-strength, and highly corrosion-resistant austenitic stainless steel bolts. They are environmentally friendly products that do not require heat treatment.

The "high-strength, high-corrosion-resistant stainless steel bolt" is made from austenitic stainless steel based on SUS304 and exceeds the strength classification A2 standard values of JIS B 1054. Through a proprietary molding process (patent obtained), it has achieved strength without the need for heat treatment. 【Features】 - Uses high-corrosion-resistant austenitic stainless steels SUS304 and SUS316 - Achieves high strength by utilizing material strength and work hardening through forging - The proprietary Bausinger effect suppression processing method eliminates the need for strengthening heat treatment, reducing environmental impact - Maintains high corrosion resistance and shortens lead time due to the absence of heat treatment processes - The screw head shape adopts a hexalobular design that offers high torque transmission - Balances corrosion resistance and strength, with a proven track record for use in automotive components (Note) The Bausinger effect refers to the phenomenon where, after applying plastic deformation in one direction, applying a load in the opposite direction results in plastic deformation occurring at a lower stress than when a load is applied again in the same direction. If you are interested in fastening with stainless steel components, please feel free to contact us.

The three-blade design provides stable anti-loosening effects! Thanks to the high-strength friction ring, it can be reused multiple times! [Manufactured by Osaka Forming Co., Ltd.]

The "E-LOCK Nut" handled by Daiichi Industry features a three-blade design that enhances its anti-loosening function and possesses the strength to withstand repeated use. In the case of conventional two-blade products, one blade gets lodged in the thread valley, effectively resulting in a state of anti-loosening with only "one blade," leading to concerns about stability. However, this product's three-blade design effectively increases thread stability with "two blades." Additionally, durability tests under vibration showed no deformation in the three friction rings of this product, proving its ability to withstand repeated use due to the sustained effect of the springs. (Other manufacturers' nuts with high anti-loosening functions may experience deformation.) **Features** 1) The three-blade design provides a more stable anti-loosening effect compared to conventional products. 2) Prevents early detachment even if the tightening axial force decreases. 3) Strong and capable of withstanding repeated use. ★ This product is from Osaka Forming Co., Ltd.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

The "Hotron Non-Contact Switch" allows you to open and close doors without directly touching door knobs or switches, making it hygienic! You can choose from two types: the "Hand Wave Sensor," which only requires you to wave your hand, and the "Foot Switch," which only requires you to place your foot at the entrance. It reduces the risk of virus and bacterial infections in places where hygiene is a concern, such as food factories, restaurants, hospitals, and nursing facilities. 【Features】 ○ Reduces the risk of virus infection by allowing door operation without contact ○ A wide variety of options to choose from based on application and location ○ Ideal for places where hygiene is a priority, such as food factories and medical facilities ○ Prevents unnecessary detection due to the switch mechanism 【Product Lineup】 ■ Hand Wave Sensor Series ○ Exposed waterproof type, front, down, and side-facing types "PF-R5" ○ Exposed type, front-facing type "PF-R1" ○ Embedded type, front-facing type "PF-U2" ○ Exposed type, downward wide type "PF-R4" ■ Foot Switch Series ○ Slim type with wide opening, vertical beam type "PF-01S" ○ Slim type with wide opening, horizontal beam type "PF-03S" ○ Standard type, horizontal beam type "PF-05" ◎ For more details, please download the catalog or contact us.
