We have published examples of proposals for extreme resistance round head bolts, shelf dowels, and washers with protrusions!
In this document, we introduce five key points to identify potential issues that are likely to occur during mass production of cold-formed and special screws at the prototype stage. We explain questions such as "Is it a product that requires a lot of secondary processing?" and "Are there strict tolerances on unnecessary parts?" We also include unique proposal examples and product cases from Tainishi Seiko. We encourage you to read through it. 【Contents (partial)】 ■ Five key points to identify potential issues during mass production at the prototype stage - Is it a product that requires a lot of secondary processing? - Are there strict tolerances on unnecessary parts? - Are there thin sections that put a burden on the mold? - If secondary processing is required, is the product shaped for easy flow in automatic machines? - If plating is necessary, is the shape conducive to easy plating? *For more details, please refer to the PDF document or feel free to contact us.

This is a high-strength stainless steel fastener made from SUS 304CUN.
SUS 304CUN is an austenitic stainless steel (A2) that boasts high strength (A2-90, A2-100), high heat resistance, high corrosion resistance, and non-magnetic properties, making it a strong and rust-resistant high-strength material. By adding copper (CU) and nitrogen (N), it is possible to increase strength while ensuring non-magnetic properties, and it has stress corrosion cracking resistance comparable to SUS 316. Furthermore, SUS 304N2, which is SUS 304 with added nitrogen (N) and niobium (Nb), is a stainless steel that enhances strength while minimizing the reduction in ductility. It is used in structural strength members and high-pressure vessels. High-strength stainless steel washers that can withstand A2-100 specifications using SUS 304N2 have also been developed. These washers prevent plastic deformation (dimpling) around the holes of the mating components that occurs during tightening with high-strength fasteners, providing a locking effect against loosening.
A variety of fastening components and screws are available, ranging from general products known as standard items to high-performance fasteners.
【Lineup】 ■ Small screws and micro screws ■ Bolts ■ Hex socket and other hole products ■ Washers ■ Nuts ■ Tapping screws ■ Washer-integrated screws ■ Hand-tightening screws ■ Pins and retaining rings ■ Construction hardware ■ Tools

Low cost! High quality! We will meet the delivery deadline!
Our company, as a specialized manufacturer of embedded screws, has been working for many years on reducing the dimensional compression of the "incomplete screw section below the head," which is a drawback of embedded screws. Today, due to the miniaturization and thinning of industrial products, the thickness of fastening components has also decreased, and we have received numerous inquiries asking, "Can the incomplete screw section below the head be compressed?" In response, we have researched technology that allows for stable mass production without compromising the original functions of the screws, such as reduced axial force, and we are now able to fasten even very thin materials. 【Product Line】 ■ Various types of end processing ■ Various types of anti-loosening processing ■ Various types of bagging processing ■ Various standard products (pan, bind, truss, upset, trimmer, flange, etc.) ■ Low head sems, etc. *For more details, please feel free to contact us.
