Prevents loosening with a special screw thread shape! A locknut suitable for use with lightweight alloys.
"Evablock" is a locking fastener that can be used with tapped screw holes. It has a special thread shape that bites into the female thread, increasing resistance and making it less likely to loosen. Without the need for design changes, it allows for an immediate switch from current fastening methods to those with locking functionality. 【Features】 ■ Low screw-in torque ■ Locking function ■ Suitable for lightweight alloys that are prone to loosening ■ Cost reduction ■ Change only the bolt without design modifications *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.
