Medium-Strength Metric Class 8.8 Steel Hex Head Screws
Partially Threaded
These Class 8.8 steel screws are suitable for fastening most machinery and equipment. Dimensions meet ISO (formerly DIN) or DIN specifications. Length is measured from under the head.
Zinc-plated steel screws resist corrosion in wet environments. Match the thread spacing of mating components. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance.
