Asymmetric Step Kinematics
T-Pins (Stepped Pins) feature an asymmetric T-shape with a narrow stem and a wide top hat shoulder ($\Phi 2.4\text{ mm}$ expanding to $\Phi 2.8\text{ mm}$).
Deep Shoulder Binding
When picked, the narrow stem drops past the shear line, causing the wide top hat shoulder to wedge firmly against a counter-bored lip inside the plug chamber.
