Improved productivity by accommodating variations in the pilot hole diameter of the counterpart material! This is a tapping screw for thin plates!
Introducing Yamashina Co., Ltd.'s newly released tapping screw for thin plates, 'SPILEAD'. It features a three-start thread, but the height of the thread peaks is higher only for part of the screw, reducing the resistance during screwing. All three thread heights align directly below the head. This allows for a combination of low driving torque and high break torque, enabling stable fastening even with variations in pilot hole diameter and material thickness. (Patent pending) Additionally, it can be inserted steadily into the pilot hole, preventing angled entries. The time required for screwing is also shorter than that of screws conforming to JIS standards, contributing to increased productivity. 【Features】 ■ Capable of accommodating variations in pilot hole diameter and material thickness ■ Addresses variations in fastening torque of electric screwdrivers ■ Inserts straight without angling ■ Short tapping screws for thin plates, such as M4×6 *For data and material requests, please feel free to contact us through the Yamashina website: http://www.yamashina.ne.jp/

Even without a female thread, it can be screwed in! You can screw it in while creating threads in the material yourself.
This is a type of screw that can be screwed in by creating threads in the material itself, even without a pre-existing thread. Since it only requires a pilot hole to be drilled, it reduces the number of work processes and has good workability. However, because it creates its own threads, it is not suitable for places where frequent removal is necessary. Compared to regular small screws, the pitch of the threads is coarser. 【Types of Screw Sections】 There are four types of screw sections.
