Please tell us about any issues you have with special screws! [Introduction of mass production examples]

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.
