Choose a hex head fastener with the right threading, thread size, material, and strength for your equipment.
Medium-Strength Grade 5 Steel Hex Head Screws


Twice as strong as low-strength steel screws, these Grade 5 screws are suitable for fastening most machinery and equipment. For quick identification, their heads are marked with three radial lines. All screws meet ASME B18.2.1, which means they’re made to strict dimensional standards. They also meet either ASTM A449 or SAE J429 standards for material quality. Length is measured from under the head.
Black-oxide steel screws have some corrosion resistance, but they’re best for dry environments. They meet SAE AMS2485 requirements for black oxide coatings.
Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch.
