This hinge bolt is used to secure the door hinge assembly to the body and door structure. It ensures the door opens, closes, and aligns correctly with the body when installed to the correct torque. Because door hinges on classic Porsches carry significant loads from repeated use and the weight of steel doors, using the correct OE bolt helps maintain reliable hinge pivot performance and accurate panel gaps.

Functions & Technical Role:
•  Structural fastener: Holds door hinge to body and hinge bracket
•  Load-bearing: Supports repeated door movement without loosening
•  Correct OEM specification: Right thread size (M8 × 20 mm), material, and finish
•  Reliable retaining force: Helps preserve hinge alignment over time
•  Direct fit replacement: No modifications needed - OEM bolt matches Porsche parts diagrams exactly
