Hex Head High Strength Bolts ISO4014 GB5782 Class 10.9 Black Partial Thread Bolt M6 M48

High-Strength Metric Class 10.9 Steel Hex Head Screws

Product Description:

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.

Black ultra-corrosion-resistant-coated steel screws resist chemicals and withstand 1,000 hours of salt spray. To maintain corrosion resistance, use these screws with black ultra-corrosion-resistant-coated nuts and washers.

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.
