Serrated Top Driver Pins: Multiple Micro-Shear Lines Against Kinetic Raking
Engineering Overview: Technical analysis of serrated top driver pins featuring multiple micro-grooves that catch in the shear line during rapid pick manipulation.

Micro-Groove Trapping Mechanics
Serrated Driver Pins feature 3 to 5 micro-grooves (0.3 mm depth) cut along their outer diameter.
Multiple False Sets
When dynamic raking vibrates the pins upward under rotational tension, each serration acts as a micro-shear line, catching on the cylinder chamber edge. The lock picker feels false clicks at every level, unable to identify the true shear line.
Frequently Asked Engineering & Selection Questions
Q1: How do serrated pins stop lock raking?
Their multiple sharp grooves catch on the shear line edges during picking, creating dozens of false clicks that prevent the lock from opening.
