■Shinka is a tapping screw developed by Yamashina for thin plates. It can fasten thin steel plates of 0.3t or more without slipping, even without using a burring or nut. ■By eliminating burring and nuts, we can reduce processing costs, parts costs, and waste disposal costs due to fastening failures caused by slipping, which has led to its use by many customers, resulting in an annual shipment record of over 100 million units to manufacturers of home appliances and industrial equipment. ■Recently, attention has also been drawn to its fastening speed. It has been found that the cycle time from gripping the screw to completing the fastening can be shortened by 30% compared to conventional screws for thin plates when using Shinka. ■By utilizing Shinka, it is possible to reduce manufacturing costs associated with fastening by approximately 30%. ■We have uploaded a comparison video of the screwing time on YouTube.

"Shinka" is a tapping screw that can be used on materials as thin as 0.3mm without the need for a burring process. Typically, fastening thin plates involves screwing into a burring-processed hole. This is necessary because strong fastening cannot be achieved without ensuring contact with the screw through burring. However, this requires additional processing time for burring, and care must be taken to avoid damaging the burring after processing. Moreover, it incurs a lot of labor and costs, and can lead to fastening failures due to burring damage. Our product allows tapping fastening in a pre-drilled hole without burring, even on 0.3mm thin plates. It can achieve fastening with twice the torque of conventional products without burring. Using thin plates allows for weight reduction and eliminates unnecessary costs associated with burring processing and its maintenance. This results in significant cost savings and weight reduction due to the use of thin plates! It is a highly popular product. [Features] ■ Only a punch hole is required! No nuts or burring needed!! Greatly contributes to reducing processing and management costs. ■ It is difficult to spin freely even at twice the torque of conventional products, allowing for safe fastening with ample torque management! ■ The disposal costs of the counterpart materials due to spinning are also significantly reduced.
