About Hex Head Screws and Bolts

Fully Threaded

Partially 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. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Head height includes the flange. Length is measured from under the flange.

Black-phosphate steel screws are mildly corrosion resistant in dry environments. Zinc yellow-chromate plated steel screws resist corrosion in wet environments.

Screws that meet ISO 898-1 or SAE J1199 comply with specifications and testing requirements for material quality. Screws that meet ASME B18.2.3.9M or DIN 6921 comply with specifications for dimensional standards.

Medium-Strength Metric Class 8.8 Steel Flanged Hex Head Screws

Zinc Yellow-Chromate Plated

Black Corrosion-Resistant Coated

Fully Threaded

Partially Threaded

These Class 8.8 steel screws are suitable for fastening most machinery and equipment. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. All screws meet DIN 6921 specifications for dimensions. Head height includes the flange. Length is measured from under the flange.

Zinc yellow-chromate-plated screws resist corrosion in wet environments. They also meet ISO 898-1 specifications for materials. Black corrosion-resistant-coated 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.

Stainless Steel Flanged Hex Head Screws

Fully Threaded

Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Head height includes the flange. Length is measured from under the flange.

Metric screws meet DIN 6921 dimensional standards.

Medium-Strength Metric Class 8.8 Steel Serrated-Flange Hex Head Screws

These Class 8.8 screws are suitable for fastening most machinery and equipment. Serrations under the head grip the material surface for mild vibration resistance, and 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. Dimensions meet DIN 6921 specifications. Head height includes the flange. Length is measured from under the flange.

Super-Corrosion-Resistant 316 Stainless Steel Serrated-Flange Hex Head Screws

Fully Threaded

Partially Threaded

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. Serrations under the head grip the material surface for mild vibration resistance, and the flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Screws may be mildly magnetic. Head height includes the flange. Length is measured from under the flange.
