Hi,
They're not gonna snap, but you should always use a breaker Bar when loosening them - repeated torqueing them with a Ratchet Handle is when they'll snap.
At 63 ft.lbs. (torque value), they're not gonna come easy, but they will. Also, because of this, Porsche calls for replacing them each time they are removed. They are PN# 999.067.041.09 - $2.
This is because they are designed to stretch so as not to work loose - a BAD THING! But, they won't stretch a second time without potentially loosing their integrity. It's a pretty important piece of kit and with so little money involved, should not be reused - that's when you'll risk snapping them off...
Happy Motoring!... Jim'99
