Fasteners

Every bolt, nut, screw and washer in the factory catalog — with its thread size and the matching ISO/DIN standard, so you can buy a cheap generic equivalent from any hardware supplier instead of an expensive OEM number. Porsche N-numbers are themselves standardized Norm parts.

Sizes and numbers are read from the factory catalog. The ISO/DIN mapping is a guide to the equivalent standard part — confirm head drive, grade (8.8/10.9) and exact length before buying. Browse the visual catalog to see where each one goes.
