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.
Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch.
