About Socket Head Screws

Nickel Alloy Socket Head Screws
More corrosion resistant than stainless steel screws, nickel alloy screws have excellent resistance to salt water and some acids. Material is comparable to Monel. They may be mildly magnetic. Length is measured from under the head.
Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.
