![Please tell us about any issues you have with special screws! [Introduction of mass production examples]](https://image.mono.ipros.com/public/product/image/790/2001487491/IPROS13356104564171074585.png?w=280&h=280)
We have published examples of proposals for ultra-low round head bolts, shelf dowels, and washers with protrusions!
In this document, we introduce five key points to identify common issues that may arise during mass production of cold-formed and special screws at the prototype stage. We explain whether the product requires extensive post-processing, whether there are strict tolerances on unnecessary parts, and more. We also include unique proposal examples and product cases from Tainishi Seiko. We encourage you to read it. 【Contents (partial)】 ■ Five key points to identify common issues during mass production at the prototype stage - Is the product one that requires extensive post-processing? - Are there strict tolerances on unnecessary parts? - Are there thin sections that put a burden on the mold? - If post-processing is necessary, is the product shaped for easy flow in automatic machines? - If plating is required, is the shape conducive to easy plating? *For more details, please refer to the PDF document or feel free to contact us.
In response to your request to keep the head as low as possible, we have successfully achieved mass production with a head diameter of φ18 and a head thickness of 2mm using only cold forging.
We would like to introduce a case study of proposals unique to Tainishi Seiko, a manufacturer of construction materials, based on their extensive experience with "low-profile round head bolts." The manufacturer requested that the head be as low as possible. Our company was able to mass-produce a head diameter of φ18 with a head thickness of 2mm using only cold forging and without any secondary processing. [Case Overview] ■ Request - To achieve the lowest possible head ■ Proposal and Results - Mass production was achieved with a head diameter of φ18 and a head thickness of 2mm using only cold forging and without any secondary processing. *For more details, please refer to the related links or feel free to contact us.
