Black Zinc Plated Class 8.8 Steel Hex Head Screws Grade 8.8 Steel Hex Bolts
These Class 8.8 steel screws are suitable for fastening most machinery and equipment. Dimensions meet ISO (formerly DIN)specifications. Length is measured from under the head.
Zinc-plated steel screws resist corrosion in wet environments. Black ultra-corrosion-resistant-coated steel screws resist chemicals and withstand 1,000 hours of salt spray.
Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the pitch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance.
