Fully Threaded

Partially Threaded

Twice as strong as low-strength steel screws, these Grade 5 screws are suitable for fastening most machinery and equipment. For quick identification, their heads are marked with three radial lines. All screws meet ASME B18.2.1, which means they’re made to strict dimensional standards. They also meet either ASTM A449 or SAE J429 standards for material quality. 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.

High-Strength Grade 8 Steel 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 at least 25% stronger than medium-strength steel screws. Grade 8 steel hex head screws are marked with six radial lines. Length is measured from under the head.

Zinc yellow-chromate 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.

Screws that meet ASTM A354BD or SAE J429 comply with specifications and testing requirements for material quality.

Screws that meet ASME B18.2.1 or ASME B18.6.3 comply with specifications for dimensional standards.

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.

JIS High-Strength Steel Flanged Hex Head Screws

Fully Threaded

Partially Threaded

Made to Japanese Industrial Standards, these Class 10.9 steel screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. The zinc plating provides corrosion resistance in wet environments. Head height includes the flange. Length is measured from under the flange.

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.

Alloy Steel Socket Head Screws

Fully Threaded

Partially Threaded

With a tensile strength of 170,000 psi, these alloy steel screws are stronger than Grade 8 steel screws. Length is measured from under the head.

Black-oxide steel screws are mildly corrosion resistant in dry environments. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance. They are not compatible with coarse threads.

Screws that meet ASTM A574, ASTM A574M, and ISO 898-1 comply with specifications and testing requirements for material quality. Screws that meet ASME B18.3, ASME B18.3.1M, ISO 21269, and ISO 4762 (formerly DIN 912) comply with specifications for dimensional standards.
