Hex Flange Bolt 7/16" UNF Grade 8.8 (Grade 5) – Zinc Plated – Various Lengths
Premium high-tensile bolt featuring American fine thread (20 TPI). Specifically designed for heavy mechanical loads and vibration-sensitive assemblies. Thanks to the integrated flange (built-in washer under the head), this bolt provides optimal pressure distribution.
Your Advantages:
- High Tensile Strength: Manufactured from heavy-duty Grade 8.8 / Grade 5 steel.
- Vibration Resistant: The fine UNF thread prevents accidental loosening.
- Corrosion Protection: Zinc plated for long-lasting durability (indoor and outdoor use).
- Wide Application: Ideal for automotive (e.g., seatbelt mountings), motorsport, and American vehicles.
Specifications:
- Size: 7/16" UNF (20 threads per inch)
- Wrench Size: 14 mm (convenient metric head for European tools)
- Finish: Zinc Plated
- Thread Diameter: 7/16 inch (exactly 11.11 mm). This bolt's thickness sits between metric M10 and M12, but it will never fit into a metric threaded hole.
- Torque Spec: 65 Nm (48 lb-ft). This is the exact tightening torque required to secure this high-tensile connection safely and correctly.
