Tamper screws also known as tamper-resistant screws, come in various types, each designed to provide a level of security against unauthorized removal. Here are some common types of tamper screws:
Torx Tamper-Resistant (Torx TR):
Torx screws have a star-shaped recess, and the tamper-resistant version has a pin in the center, making it difficult to tamper with standard Torx tools.
Hex Pin (Hex-Pin) Tamper-Resistant:
Similar to standard hex screws, hex pin screws have a pin in the center of the hexagonal recess, requiring a special tool for removal.
Spanner (Snake-Eye) Tamper-Resistant:
Spanner screws have two holes or indentations on opposite sides of the screw head, requiring a spanner or snake-eye driver for installation and removal.
Clutch Head Tamper-Resistant:
Clutch head screws have a unique round head with a pair of recessed grooves. They require a specialized tool for installation and removal.
One-Way Screws:
One-way screws have slanted or sloped threads that allow them to be easily installed but make removal difficult. They are often used in applications where permanent installation is desired.
Tri-Wing Tamper-Resistant:
Tri-wing screws have a triangular recess, and the tamper-resistant version has a center pin. Tri-wing screws are commonly used in electronics and appliances.
Pentalobe Tamper-Resistant:
Pentalobe screws have a five-pointed star-shaped recess. The tamper-resistant version may have a center pin, making it more secure against tampering.
Security Torx (Torx Plus Security):
Security Torx, or Torx Plus Security, is an enhanced version of Torx with larger lobes and a pin in the center. It provides additional security against tampering.
Tamper-Proof Spanner Nut:
Tamper-proof spanner nuts have two holes or grooves on opposite sides, requiring a spanner or special tool for installation and removal. They are often used in conjunction with bolts.
Pin Hex (Socket Pin) Tamper-Resistant:
Pin hex screws have a pin in the center of the hexagonal recess. This pin makes it challenging to use standard hex tools for removal.
Socket Pin Tamper-Resistant:
Similar to pin hex, socket pin screws have a pin in the center of the socket recess, preventing the use of standard sockets for removal.
Snake-Eye (Two-Hole) Tamper-Resistant:
Snake-eye screws have two holes or indentations on opposite sides of the screw head. They require a specific tool for installation and removal.
Triangular Tamper-Resistant:
Triangular screws have a three-sided recess, and the tamper-resistant version may have a center pin. Triangular screws are less common but offer tamper resistance.
Oval Pan Head Spanner Tamper-Resistant:
Oval pan head spanner screws have a rounded, oval-shaped head with spanner features for increased security.
These are just a few examples of tamper-resistant screw types. The choice of a specific tamper-resistant screw depends on the level of security required and the application. Different industries and settings may use specific tamper screws to meet their security needs.
