About Hex Head Screws and Bolts

Choose hex head fasteners with the right threading types, thread sizes, and material for your equipment.

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 steel and zinc-plated steel screws are a good choice for most applications and 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.

Medium-Strength Metric Class 8.8 Steel Hex Head Screws

Fully Threaded

Twice as strong as low-strength steel screws, these metric Class 8.8 steel screws can be used to fasten most machinery and equipment. Dimensions meet ISO (formerly DIN) or DIN specifications. Length is measured from under the head.

Zinc-plated steel screws are a good choice for most applications. They 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.
