The product name, "Hanzawa Screw", is inspired by the Japanese TV drama "Hanzawa Naoki" renowned around Asia, where the main character Hanzawa working for the largest bank in Japan faces numerous obstacles from upper management as he returns with 100-fold revengence and climbs his way up the ranks.  Based on cross recess, the "Hanzawa Screw" head recess is formulated into "半" (the word symbolizing "Hanzawa") shape, and the head is coupled with the words "勝守" (meaning the guardian to help you gain sucess) and acts as a protective charm.

The main feature of the product is that it is as real as a countersunk plastic screw. Users can use a Philips head screwdriver to fasten it. The company, Hanzawa Steel (半澤鋼業) states, "It is never called a screw if we cannot fasten it." In addition to the head design, the package includes the words "１００倍成就" (100-fold achievement in return!).
