We will protect your valuable products from theft and malicious disassembly!
The anti-tamper screw TRF is a security measure screw that is difficult to remove without using a special tool. It cannot be removed with commercially available screwdrivers or wrenches, making it suitable for preventing tampering, disassembly, theft, and for safety measures. Additionally, due to the special shape of the screw head, it is increasingly being used as a "design screw." There are over 10 types of screw head shapes and 3 types of nut shapes to choose from. TRF is available for immediate delivery and can be purchased from just one piece. Sizes range from M2 to M12 (nuts up to M16), and inch sizes are also in stock. Sales to individuals are not available. We do not sell removal tools separately. Compliant with RoHS directives. If you have any other questions regarding our products, please feel free to contact us.

basic information
1) Pin-Inserted Hex Socket A type with a pin standing inside the hex socket. Provides good torque transmission during tightening. 2) Pin-Inserted 6-Lobe A pin stands in the center of the star-shaped hole, preventing a standard 6-lobe wrench from fitting. Offers good torque transmission without cam-out, ensuring excellent workability. 3) Two-Hole A type preferred for its design with two holes. Can also be used for decorative purposes. 4) One-Side Tightening is done using a standard flathead screwdriver, while removal requires a "One-Side Removal Tool." Since there is no recess in the head, dust does not accumulate, making it suitable for outdoor use. 5) Tri-Wing In the triangular hole, both flathead and Phillips screwdrivers will spin freely. 6) System 5 The head has no holes, and its round shape with five grooves cannot be grasped with pliers. 7) Tri-Cle Since its launch, it has received a significant response, especially as it was highly requested by customers. 8) Cross Pin A pin stands in the center of the cross-shaped hole, preventing a standard Phillips screwdriver from fitting.
