Choose these screws for their adherence to strict military standards for material and construction. Dimensions meet Fed. Spec. FF-S-86 specifications. Screws 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.
