Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Wire these screws together through the hole in the head to get more vibration resistance than any other screw (wire sold separately). Dimensions meet ASME B18.2.1 specifications. Length is measured from under the head.

Screws are alloy steel with a tensile strength of 170,000 psi, making them stronger than Grade 8 steel screws and more than twice as strong as stainless steel wire-lockable screws. Their black-oxide finish provides mild corrosion resistance in dry environments. For more vibration resistance than any other socket head screw, wire these screws together through the hole in the head (wire sold separately). Dimensions meet ASME B18.3 specifications. 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.

Screws are 18-8 stainless steel for good chemical resistance. They may be mildly magnetic. For more vibration resistance than any other socket head screw, wire these screws together through the hole in the head (wire sold separately). All screws meet ASME B18.3 and ASTM F837 for dimensional standards and material quality. Length is measured from under the head.
