Tampered Proof Button Head

Description

HBS Fasteners manufactures premium Button Head Tamper-Proof Screws, the ideal choice for applications where a flush-mount countersunk screw isn’t possible, but high security is still required. The rounded “Button” head has no sharp edges, making it difficult to grip with pliers or wrenches. The center security pin in the drive prevents standard Torx or Hex keys from seating, requiring a specialized security bit for installation. This makes it a perfect “theft-deterrent” fastener for exposed public installations and sensitive electronic housings.
