• Torx styled, star drive button head security machine screws in this selection have an added pin in the middle of the drive making it more secure.
• Only specific torx or star (with pin) bits will be able to easily remove these types of machine screws.
• These security screws are best for metal to metal application, used for securing materials from being tampered with such as in food prep and processing areas.
• You will often see security screws used in bathroom stalls and other public locations. The Star (with pin) drive style also deters stripping when installed correctly.
• Since the pressure on the head is more evenly distributed, higher torque can be applied without increased risk of stripping.
