Anti-Raking Dynamics
Lock raking uses wavy pick tools scrubbed across the keyway to bounce pins into position rapidly. Mushroom Driver Pins prevent this via asymmetric conical heads.
Conical Binding Geometry
- Asymmetric Head: Features a flat base with a conical tapered head ($\Phi 2.4 ext{ mm}$ expanding to full diameter).
- Tilt-Lock Action: When dynamic raking lifts the pin under rotational tension, the tapered head tilts sideways and wedges tightly against the chamber chamber rim, blocking rotation.
Frequently Asked Engineering & Selection Questions
Q1: How do mushroom pins differ from spool pins?
Mushroom pins have a tapered conical head that tilts and wedges into the chamber rim under tension, specifically countering dynamic raking tools.
