Hiro Seiko have introduced a new series of stainless steel screws to their large existing product line. A first in the R/C industry, these colored steel crews are denser than a normal alloy screw, but also heavier so not only will it look great but it will provide more strength to areas that need it. Available in t-blue, red, purple and smoke-black in sizes M3×6, M3×8, M3×10, M3×12, M3×14, M3×16, M3×18 & M3×20 they come in countersunk or done head versions, both with hex drive.
