Features: Designed for straightforward use with the appropriate specialized tool, these Three-slot Safety Nuts align with standard installation processes for security fasteners. Their compatibility with 1/4"-20 threads and durable Zamak 5 Zinc construction allows for use in multiple scenarios, from professional projects to personal equipment upgrades requiring enhanced security. The tapered, smooth outer profile and recessed Tri-groove drive make these nuts resistant to gripping with standard tools like pliers or wrenches. This physical characteristic adds a layer of difficulty to improvised removal attempts. Specifications: Material: Zinc alloy Size: 0.7 x 0.3 inches Package includes: 20 x Tri-groove tamper proof t groove security nuts Notes: Manual measurement, please allow slight errors on size. The color may exist a slight difference due to different screen displays

  • Complete Set of 20 Pieces: You will receive 20 Tri-groove Tamper Proof T Groove Security Nuts, a sufficient number to cover daily usage, replacement needs, and potential sharing with colleagues or acquaintances working on similar projects. These nuts arrive ready for immediate use in various applications requiring security fasteners
  • Specified 1/4"-20 Thread Size: These Three-slot Safety Nut features a 1/4"-20 thread size, compatible with corresponding bolts and hardware. The nuts follow standard dimensions that fit most equipment and structures designed for this thread specification, ensuring seamless integration into your existing setups
  • Zamak 5 Zinc Alloy Construction: These Anti-theft nuts are made from Zamak 5, a zinc alloy known for its favorable mechanical properties. This material selection contributes to the component's structural integrity for its intended security function
  • Specialized Tri-groove Tamper Proof Design: The unique three-slot (T-groove) structure enables anti-theft functionality, as the tapered three-pronged drive requires a specialized socket for installation and removal. The rounded, tapered shape makes it difficult to grip with standard tools, preventing unauthorized access to secured items without proper equipment (socket not included)
  • Versatile Applications: Suitable for industrial, commercial, and high-security settings, these Tri-groove Tamper Proof Nuts work well with public facilities, surveillance cameras, guardrails, playground equipment, park benches, vehicles, and roof tents.
