Metalnics (Aich) introduced CFRTP bolts that are lightweight and have excellent heat resistance at "Nagoya Manufacturing World 2021" (April 7-9, Port Messe Nagoya).

CFRTP bolts are bolts molded by CFRTP using PEEK, a thermoplastic resin, as the base material of carbon fiber reinforced plastic.

It weighs about one-sixth that of metal fasteners and is about 50% stronger than resin fasteners. It also has excellent heat resistance (about 250 degrees), high conductivity, and can contribute to static electricity countermeasures. It has many features such as non-magnetism, corrosion resistance, and chemical resistance. The molding method is injection molding and there is no secondary cutting process.

The company imports and sells CFRTP bolts from Europe. The lineup is M4 to M6 sizes of countersunk screws (DIN991). Bolt (DIN912) M3 to M6 sizes. M4 to M6 of the nut (DIN934).
