Carbon steel Serrated-Flange Socket Head Screws, JX-22JG514-M8-16-ST

Serrations under the head grip the material's surface for mild vibration resistance, and the flange distributes pressure, eliminating the need for a separate washer. With a tensile strength of 140, 000 psi, these alloy steel screws are comparable in strength to Grade 8 steel screws and are stronger than stainless steel screws. Their black-oxide finish provides mild corrosion resistance in dry environments. Head height includes the flange. Length is measured from under the flange.

1. Medium-Strength Metric Class 8.8 Steel Flanged Hex Head Screws

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.

2. Stainless Steel Flanged Hex Head Screws. 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.

Inch screws meet ASTM F593 material quality standards and IFI 111 dimensional standards. Metric screws meet DIN 6921 dimensional standards.
