Types of Metric Flange Screws 

Metric Class 8.8 Hex Flange Bolt, Serrated, DIN 6921, Zinc CR+3

These Class 8.8 serrated flange bolts provide dependable fastening strength with built-in vibration resistance. The serrations lock the fastener in place while the flange distributes load. Zinc CR+3 coating ensures corrosion resistance and a bright silver appearance.

Metric Class 8.8 Hex Serrated Flange Bolt, DIN 6921, Zinc Yellow CR+6

Designed with serrations for anti-vibration hold, these Class 8.8 bolts provide consistent strength. The zinc yellow CR+6 finish adds strong corrosion protection with a gold-toned appearance. They are frequently used in automotive and equipment assemblies where durability and finish matter.

Metric Class 8.8 Hex Flange Bolt, Non Serrated, DIN 6921, Plain

Plain finish non-serrated bolts offer Class 8.8 strength for dependable fastening. The integrated flange spreads load without surface damage. These bolts are commonly used in cost-sensitive construction and equipment projects.

Metric Class 8.8 Hex Flange Bolt, Non Serrated, DIN 6921, Zinc CR+3

These bolts deliver Class 8.8 performance with a non-serrated flange for even load distribution. Zinc CR+3 coating protects against corrosion while maintaining a clean appearance. They are used widely in machinery and industrial applications.

Metric Class 8.8 Hex Flange Bolt, Non Serrated, DIN 6921, Zinc Yellow CR+6

These bolts feature Class 8.8 alloy steel strength with a zinc yellow CR+6 finish. The gold-toned coating provides resistance to corrosion and adds visual contrast. They are selected in automotive and mechanical builds for both strength and appearance.

Metric Class 10.9 Hex Flange Bolt, Non Serrated, DIN 6921, Plain

Class 10.9 bolts provide higher tensile strength than Class 8.8, suitable for more demanding assemblies. The plain finish highlights raw steel performance for indoor environments. These are used in structural and mechanical applications requiring maximum strength.

Metric Class 10.9 Hex Flange Screw, Non Serrated, DIN 6921, Zinc CR+3

These screws combine Class 10.9 tensile capacity with a zinc CR+3 finish for long-lasting corrosion resistance. The silver coating offers a professional look while protecting against wear. They are often used in machinery and equipment where strength and appearance are both important.

Metric Class 10.9 Hex Flange Screw, Non Serrated, DIN 6921, Zinc Yellow CR+6 Bake

These Class 10.9 screws provide extreme strength with a zinc yellow CR+6 baked finish. The baked process reduces hydrogen embrittlement while ensuring superior corrosion resistance. Their gold-toned coating is favored in automotive and heavy equipment projects.

Metric Class 10.9 Hex Flange Bolt, JIS B1189 Type 2, Zinc CR+3

Built to JIS standards, these bolts offer Class 10.9 strength and reliable load distribution. The zinc CR+3 coating adds durability and corrosion protection. They are frequently specified in machinery and structural assemblies.

Metric Flange Bolts - Available Finishes

South Coast Fasteners offers metric flange bolts in a full range of finishes to protect against corrosion and enhance appearance.

Zinc CR+3

Zinc CR+3 provides a bright silver finish with strong corrosion protection. It is widely used in automotive, construction, and equipment assemblies where strength and appearance both matter. This finish ensures durability while maintaining a clean, professional look.

Zinc Yellow CR+6

Zinc yellow CR+6 offers the same protection as CR+3 but with a distinctive gold appearance. It is often used in automotive and mechanical applications where fastener visibility or differentiation is important. This finish delivers reliable resistance to wear and corrosion.

Plain Finish

Plain finish fasteners highlight the raw strength of alloy steel without coatings. They are used in controlled environments where corrosion is minimal. This finish provides cost efficiency and reliable performance where additional protection is not required.

Zinc Yellow CR+6 Bake

Zinc yellow CR+6 bake adds enhanced corrosion protection while minimizing hydrogen embrittlement risk in high-strength screws. The baked finish delivers long-term durability under stress. This coating is commonly specified in automotive, heavy machinery, and structural applications requiring both strength and safety.
