Tools you'll need

See the full tools list for where to buy each one and budget alternatives.

A single place to look up the fasteners you’ll meet on a 944, 944 Turbo, 924S or 968. The specs here are pulled from the individual repair guides — each section links back to the procedure it came from, where you’ll find the full context, tools and sequence.

Before you reach for the torque wrench. Values vary by model year and by whether a fastener is reused — always confirm against the specific procedure for your car. Where the original gave only one unit, the converted value is marked with ≈. Angle-tightening (e.g. +60°) means turn the fastener the stated angle after the initial torque, using a paint mark to track it.

General fastener torque

When a specific value isn’t called out, these are the default torques by thread size:

Thread sizeTorque
6 mm8 Nm (6 ft-lb)
8 mm20 Nm (15 ft-lb)
10 mm40 Nm (29 ft-lb)

Cylinder head

Head bolts are not a single value — they use a staged torque-plus-angle procedure that differs by engine (M44 variant). Use the dedicated guide for the correct sequence and figures for your car.
