Hollymetal® Action Fasteners Hollymetal® is an alloy consisting of zinc and tin, the alloy of these two metals provides superior corrosion resistance. this unique coating was design by Mechanical Plating in 1982. Hollymetal® coatings at 45 microns meets the stringent requirements of corrosion resistance, complies and exceeds the 'Standard' AS 3566 for Class 4. Hollymetal® is the coating used on Action Fasteners fasteners, mechanically galvanised under strict in-house facilities here in Australia. The process Mechanical Plating is a process that requires no heat or electrolysis and does not induce hydrogen embrittlement and is suitable for high tensile components | | Unique C4 head marking to identify Hollymetal® |  | | Glass beads form a major function in the mechanical galvanising process | |  |
