CNC technology, fine polishing, smooth surface!
Tips: We are paired with a better 304 stainless steel screw, not the ordinary 201 screw.
304 stainless steel is better, harder, stronger and bigger. The head has vertical stripes and no rust.
Even if it is a screw, RISK takes it seriously!
Steel flower screw,steel sheet thick, stronger locking force!
