Prevents loosening with a special screw thread shape! A locknut fastener suitable for use with lightweight alloys.
"Evablock" is a locking fastener that can be used for tapped holes as well. 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 the current fastening method to one with a locking function. 【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 localize tapping screws in 1954. The company holds data on over 200,000 types of screws and bolts, enabling the high-quality manufacturing of various shaped products. Recently, it has focused on investing in research and development, 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. The company is committed to innovative technological development without being bogged down by history.
