Das Kaltstauchverfahren ist eines der neuen Verfahren für die Druckbearbeitung mit weniger oder gar keiner Zerspanung
Metall. Es handelt sich um eine Verarbeitungsmethode, die die plastische Verformung von Metall unter der Einwirkung von
äußere Kräfte, und mit Hilfe von Formen wird das Metallvolumen umverteilt und in die Form gebracht
die gewünschten Teile oder Rohlinge. Das Kaltstauchverfahren ist am besten geeignet für die Herstellung von Standard
Verbindungselemente wie Bolzen, Schrauben, Muttern, Nieten, Stifte usw.
A triangular raised safety bolt is a specialized fastener designed to provide enhanced security by deterring tampering or unauthorized removal. Here are its key characteristics:
Features:
-
Triangular Head Design:
-
The bolt has a three-lobed (triangular) raised head, requiring a matching triangular socket or driver for installation/removal.
-
Unlike standard hexagonal or Phillips heads, this shape makes it difficult to grip with common tools like wrenches or pliers.
-
-
Raised or Domed Profile:
-
The head is slightly raised or domed, preventing easy access to the edges with prying tools.
-
The smooth, curved surface makes it hard to grip with locking pliers or vice grips.
-
-
Tamper-Resistant:
-
The uncommon shape acts as a deterrent against casual tampering.
-
Often used in public fixtures, security panels, or high-theft-risk applications.
-
-
Material & Finish:
-
Typischerweise hergestellt aus hardened steel, stainless steel, or brass for durability.
-
May have corrosion-resistant coatings (e.g., zinc plating, black oxide) for outdoor use.
-
-
Gewindetypen:
-
Available in machine thread (bolts) oder self-tapping thread (screws) depending on application.
-
Common Uses:
-
Security panels & enclosures
-
Dreieckiger erhöhter Sicherheitsbolzen
-
Public infrastructure (e.g., restroom fixtures, signage)
-
Electronics & machinery requiring restricted access
-
Transportation (e.g., license plates, rail components)
