TPR is a tamper proof recess which is desinged to prevent disassembly.
Features:
TPR is the product for the special driving parts that have critical points to be kept inaccessible to users for protecting product functions or for the sake of safety and thus require the screws that cannot be loosened by commercially available bits.
Applications:
In some cases to be kept non-removable, TPR is one of excellent solutions.
