High-Strength Metric Class 10.9 Steel Hex Head Screws
Fully Threaded
Partially 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. Blue-dyed screws are easy to distinguish.Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the pitch.
