About Hex Head Screws and Bolts

Plastic Hex Head Screws
Fully Threaded
Partially Threaded
Plastic screws are chemical and oil resistant, nonconductive, and lightweight. Not recommended for high-strength fastening. Length is measured from under the head.
Nylon screws may expand when exposed to moisture.
Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. Fine threads are closely spaced to prevent loosening from vibration.

High-Strength Grade 8 Steel
Thread-Locking Hex Head Screws
Fully Threaded
Partially Threaded
Made from Grade 8 steel, these screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are more than twice as strong as our stainless steel thread-locking screws. A nylon patch bonded to the threads adds friction to resist loosening from vibration. These screws have a zinc yellow-chromate plating that provides corrosion resistance in wet environments. Material meets SAE J429 specifications for quality. Dimensions meet ASME B18.2.1 specifications. Grade 8 steel hex head screws are marked with six radial lines. Length is measured from under the head.

Medium-Strength Metric Class 8.8 Steel
Thread-Locking Hex Head Screws
These Class 8.8 steel screws are suitable for fastening most machinery and equipment. They are over 50% stronger than stainless steel thread-locking screws. A nylon patch bonded to the threads adds friction to resist loosening from vibration. These screws have a zinc plating that provides corrosion resistance in wet environments. Dimensions meet ISO 4017 (formerly DIN 933) specifications. Length is measured from under the head.
