All our zinc-plated parts meet this specification (unless otherwise stated).
🛡️ Corrosion protection: low
Thin 3 to 5 µm zinc coating, suitable for environments with low exposure.
🧂 Salt spray resistance: 24 to 96 h
Indicative resistance before the appearance of rust, depending on the coating finish.
🏠 Recommended environment
Indoor applications or environments with very low exposure to moisture.
🔩 Threads preserved
The low coating thickness limits dimensional variations and helps maintain thread accuracy.
How to determine the diameter of a UNC or UNF screw:
The number of threads per inch will determine the diameter of the screw or nut of an American UNC or UNF screw.
Simply count the number of threads per inch (i.e. 25.4 mm) and refer to the table below.
For diameter 1 inch: 8 threads for 1 inch (25.4 mm) = UNC THREAD
