Hydraulic Corkscrew Pulling Defense
Attackers drive hardened self-tapping screws into the keyway to pull the plug out axially using hydraulic jacks.
15 kN Mechanical Anchorage
- Flanged Inner Shoulder: A wide $\Phi 15.0\text{ mm}$ mechanical shoulder on the inner end of the plug bears against the solid brass body bulkhead.
- Heavy-Duty Circlip: 0.8 mm spring steel retaining ring (58 HRC) locks the core against $>15\text{ kN}$ axial tensile pull.
Frequently Asked Engineering & Selection Questions
Q1: What stops a lock core from being pulled out with an extraction tool?
A wide mechanical flange on the back of the plug and a hardened steel retaining ring anchor the core firmly inside the brass body.
