Hex Head Screw Assortments
These assortments include hex head screws and hex nuts. Length is measured from under the head.
Grade 5 and Class 8.8 steel screws are suitable for fastening most machinery and equipment. Zinc-plated steel screws resist corrosion in wet environments.
Grade 8 and Class 10.9 steel screws are about 25% stronger than Grade 5 and Class 8.8 steel screws. Zinc yellow-chromate plated steel screws are more corrosion resistant than zinc-plated screws in wet environments.
