Step 88: Tamper Pin TX security Screws
The Tamper Pin TX Security Screw as its name states has an internal pin within the 6-lobe socket (star drive) of the head, requiring a special insert bit or key wrench to insert and remove. This unique feature renders the Tamper Pin TX Screw tamper proof, reducing the risk of vandals or intruders tampering or undoing the screws. Due to the design of the Tamper Pin TX Security Screw it is suitable for higher torque applications and is "2 way".
Except for the pin, the Tamperproof Torx® heads are the same as the internal recess heads, with sizes including - TT-7, TT-8, TT-9, TT-10, TT-15, TT-20, TT-25, TT-27, TT-30.[[br]]
