How do I measure the length of a screw?
The length of a countersunk screw is measured with the head. For all other heads, the length is measured under the head.
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.
