Ultimate tapping screw for resin
"DELTA PT" is a tapping screw designed for resin, with a special shape for the screw threads and valleys to smooth the deformation flow of plastic. When screwing into plastic, the deformation of the female threads in the plastic is smooth, which reduces damage to the plastic during insertion and tightening. It is also resistant to vibrations and temperature changes, maintaining a secure fastening even after long-term use, allowing for weight reduction and miniaturization, as well as cost reduction and resource recycling. 【Features】 ■ Specially designed shape for screw threads and valleys ■ Reduces damage to plastic during insertion and tightening ■ Resistant to vibrations and temperature changes ■ Allows for weight reduction and miniaturization ■ Enables cost reduction and resource recycling *For data and material requests, please feel free to contact us through the Yamashina website: http://www.yamashina.ne.jp/

Company information
Established in 1917, during the dawn of mass production of screws in Japan, the company succeeded in producing the first domestic cross-recessed screws in 1949 and cooperated with the government to domesticate tapping screws in 1954. We hold data on over 200,000 types of screws and bolts, enabling us to manufacture a variety of products with high quality. Recently, we have been focusing on research and development investments, working on tapping bolts with a diameter of 6mm or more, high-strength aluminum bolts, tapping screws for thin steel plates, and tapping screws for CFRP, which will support the next generation. We are committed to challenging innovative technology development without being bound by history.
