Irisart® is a precision-made screw hole reinforcement product manufactured through cutting processes. As a result, pitch jumps that often occur with coil types do not happen. Additionally, there are no issues with the ends of the coils protruding, and since it is tangless, tang cutting is not necessary. ■ It is ideal for reinforcing screw holes in plastics, resins, light metals, and iron plates. ■ It can be easily and quickly inserted by anyone using a dedicated insertion driver. ■ Being tangless eliminates the hassle of tang removal, significantly reducing work time. *For more details, please contact us or download the catalog.

An insert nut is a type of nut used when molding plastics such as resin. It is embedded in the plastic material for use. This product allows for easy reinforcement and repair of screw holes by directly screwing into the material. Installation onto the counterpart material can be easily done using a dedicated tool. The main body is coated with a locking agent, so there is no concern about loosening after installation. 【Product Specifications】 Please refer to the catalog for detailed sizes and part numbers.

At Hiroseki Instrument Co., Ltd., we handle two types of "insert nuts": screw-in type and press-fit type. The "screw-in type" is an embedded nut used for reinforcing or repairing screw holes in materials such as plastic, light metals, and steel plates. It can also be utilized for reprocessing defective female threads in plastic, light metals, steel plates, and products through tapping. When the strength of the female thread is weak and cannot provide sufficient tightening force during tapping, inserting this nut allows for reliable screw fastening. The "press-fit type" is an insert used after resin molding, which is inserted into a formed hole during molding using press-fit or heat press methods to create threads. *We also handle "insert collars" (for press-fit and simultaneous molding). 【Screw-in Type Insert Nut Features】 ○ Machined with high precision on NC automatic lathes, ensuring stable quality after insertion. ○ Easy for anyone to insert, resulting in high-strength female threads in a short time. ○ Using a locking mechanism during insertion increases the fixing strength of the product, allowing for reliable screw fastening. ○ Fixed by screwing into a pre-tapped hole using an insertion tool.

The brass duct insert (standard type) "HSD" is designed to insert an insert nut into a formed hole during molding using a press-fit or heat-fit method to create threads. It is an expanded type insert nut used after molding, with a tip that has a cross-slit knurling and a shape that is narrowed with an expansion plate inside. It is pressed into the resin hole from the knurled tip, and by pushing down the expansion plate with a punch, the tip is expanded outward, allowing the knurling to grip firmly into the resin. Therefore, it can also be used when the boss thickness is relatively thin. Additionally, because it is an expansion type, it can accommodate a wide range of applications regardless of the material of the counterpart. For more details, please download the catalog.

Insert nuts are pressed and inserted into the insertion holes formed during molding using pressure and heat insertion methods to create threads. 【Product List】 ○ Dodge Insert: HSD/HFD - Cross-slit shape - Usable for thin-walled counterpart materials ○ Bit Insert: HSB/HSB-Z/HFB - General-purpose type - Cost-effective and well-balanced ○ Ultra-Sert: HUDII - Tapered shape - Easy to set and has good thermal conductivity ○ Ultra-Sert: HUDIV - Asymmetrical knurled shape - Excellent tensile and torque strength ○ Mini Bit Insert: HMIB-Z - Mini size - Compatible with miniaturization of counterpart materials ● For other functions and details, please contact us.
