Hardened Steel Face Caps: Encapsulating Brass Plugs Against Chisel Cleaving
Engineering Overview: Engineering breakdown of case-hardened stainless steel face caps wrapped over brass cylinder plugs to defeat cold chisel and hammer cleaving attacks.
Technical & Engineering Specifications
| Standard | Sold Secure Diamond / EN 1303 Grade D |
|---|---|
| Armor Type | Hardened Stainless Steel Front Cap |
| Protection | Defeats Cold Chisels, Impact Cleaving, and Pry Wedges |
| Cap Thickness | 1.5 mm Case-Hardened Steel (60 HRC) |
Front-Face Structural Reinforcement
Heavy chisel blows can split the front of brass plugs along the keyway slot. High-security cylinders cap the plug with a case-hardened steel armor cap (60 HRC).
Armor Encapsulation
- 1.5 mm Hardened Steel Cap: Mechanically crimped over the brass plug nose.
- Impact Deflection: Distributes hammer and chisel impact energy across the entire cylinder body without deforming the keyway broach.
Frequently Asked Engineering & Selection Questions
Q1: What is a hardened face cap on a lock cylinder?
A hardened steel cap crimped over the front of the brass core to protect it from being split open by cold chisels or hammers.
