Fasteners
Is there concern about galvanic corrosion when different types of zinc-coated steel are in contact?
There is not a concern of dissimilar metals corrosion (galvanic corrosion) when pairing zinc-coated steel of different types (for example when pairing a hot-dip galvanized
Is it possible to have steel with chemistry that is too good for galvanizing?
It is possible to have steel chemistry with levels of silicon and phosphorus that are too low to meet the minimum thickness levels specified in
Hot-dip galvanizing small parts, hardware, and fasteners to ASTM A153
ASTM A153 governs zinc coatings applied by the hot-dip process on iron and steel hardware, including nails, bolts, nuts, fasteners, and rods. The hot-dip galvanizing
Clogged Threads
Clogged threads are caused by poor drainage of a threaded section after the product is withdrawn from the galvanizing kettle. Clogged threads, as seen below,
Clogged Holes
Clogged holes are a defect caused by molten zinc metal not draining adequately and partially or completely filling holes with excess zinc. Molten zinc will
