Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. A thread locker bonded to the threads adds friction to resist loosening from vibration. Dimensions meet ASME B18.3 or ISO 4762 (formerly DIN 912) specifications. Length is measured from under the head.

Screws with a nylon patch are reusable, but their holding power lessens with each use. Screws with an epoxy adhesive provide a permanent bond; once tightened, the epoxy expands to seal the gaps between the mating threads.

Metric screws are also known as A2 stainless steel screws.

Coarse threads are the industry standard; choose these screws if you don’t know the pitch or the threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.
