Product description
High-Strength Metric Class 10.9 Steel Flanged Hex Head Screws
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.
