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/

[Theft Prevention!] This is a screw that is difficult to remove unless a special tool is used.
Tamper-proof screws refer to screws that are difficult to remove without using a specialized tool. Additionally, they have good torque transmission, which means that the screwdriver is less likely to lift off from the hand. The screw holes have a design element, so they can also be used for decorative purposes. Recently, various shapes have been in demand. 【Category】 ■ Pins, Hexagonal ■ TRF (TRX) Pins ■ Tri-Wing ■ Two-Hole Please feel free to contact us for more details. ↓ ↓ ↓ ↓ ↓ ↓ ↓
No tools needed! It can be easily tightened with your fingers.
Screws that are tightened with fingers are collectively referred to as "knob screws." They are ideal for places that are used repeatedly and are commonly found in lighting fixtures and furniture. In a broader sense, wing nuts are also a type of knob screw. Depending on the application, there are various materials and shapes available. ■ Urea screws and thumb screws, etc. They have a resin head, which makes them highly safe. They do not require high strength for pulling out, etc. ■ Butterfly bolts and eye bolts They have a metal head and are used for assembly, among other things.

The only lineup of molded plastic inch screws in the country!
The materials are available in two types: PEEK and RENY. The diameter sizes include #2-56, #4-40, #6-32, #8-32, #10-24, #10-32, and #1/4-20, with lengths ranging from 3/16 to 1-1/4 inches. We have received inquiries from various sectors and plan to expand our lineup in the future. - Used for maintenance of medical devices made in the USA Medical devices use inch screws made of resin produced in the USA, but since the quantity needed for regular maintenance is small, importing them incurs time and costs. Our resin-made inch screws are molded products, making them more affordable and quicker to obtain than manufacturing through cutting processes domestically. *For more details, please refer to the PDF document or feel free to contact us. *Online shop here → https://www.chemisnetshopping.co.jp/
By incorporating the seat washer into the screw in advance, it prevents forgetting to insert it or losing it!
This is a screw that has a washer incorporated into it in advance to prevent loosening and to avoid the sinking of the seat surface. 【Features】 ■ Since the washer is incorporated before the screw threads are rolled, it will not come off the screw. ■ Eliminates the hassle of inserting the washer and the worry of losing it, thereby improving work efficiency. ■ Prevents forgetting to incorporate the washer into the screw. Please feel free to contact us for more details.
