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) 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.

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. Those that are blue dyed are easy to distinguish.

Steel screws are best for dry environments, since moisture will cause them to rust. They don’t require much surface preparation before applying a finish, so you can add your own paint or coating.

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.

Super-Corrosion-Resistant 316 Stainless Steel Hex Head Screws

Fully Threaded

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. They may be mildly magnetic. Length is measured from under the head.

Match the thread spacing of mating components. Fine threads are closely spaced to prevent loosening from vibration.

Screws that meet ASME, ISO (formerly DIN), or DIN specifications comply with these dimensional standards.
