215mm Flywheel 7mm Clutch Bolt - 1.1 (FA), 1.6 (AS), 1.8 (Type 4)

This M7 clutch bolt is a correct replacement fixing for securing the clutch pressure plate to the flywheel on a range of classic Volkswagen engines. It is suitable for Baywindow Buses, Mk1 Golf, and Scirocco models that originally used M7 x 18mm bolts, which are no longer available in that exact length.

These bolts are now supplied in M7 x 25mm form and must be shortened to the correct length before installation, replicating the original factory specification.

What this part does

Clutch bolts are responsible for clamping the pressure plate securely to the flywheel, allowing the clutch assembly to transmit engine power to the gearbox while still enabling smooth disengagement during gear changes. Correct bolt size, strength, and seating are critical—incorrect fixings can lead to clutch slip, vibration, or catastrophic clutch failure.

How it works

The bolts pass through the pressure plate and thread into the flywheel, evenly clamping the clutch assembly when torqued correctly. Because these applications use M7 hardware, accuracy is especially important. This replacement bolt provides the correct thread and strength, allowing it to be cut down to the original 18mm length for safe and correct installation.
