Mil. Spec. Alloy Steel Socket Head Screws
Partially Threaded
Choose these screws for their adherence to strict military standards for material and construction. With a tensile strength of 160,000 psi, these alloy steel screws are stronger than Grade 8 steel screws. They're cadmium plated to resist corrosion in wet environments. Length is measured from under the head.
Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.
