About Hex Head Screws and Bolts

Fully Threaded

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. 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.

High-Strength Metric Class 10.9 Steel Hex Head Screws

Fully Threaded

Choose these Class 10.9 steel screws for high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. Dimensions meet ISO (formerly DIN) or DIN specifications. Length is measured from under the head.

Zinc yellow-chromate plated and 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.
