Torx Security Ultracon Screws

Torx Tamper-Resistant UltraCon Masonry Screws are the optimal fastening solution for use in concrete, brick, or hollow block. This unique screw combines the security feature of a Torx tamper-resistant drive with the superior quality and easy installation of an UltraCon masonry screw.

The special Hi-Lo thread literally taps threads into masonry materials. The high, sharp thread with its notched cutting edge cuts deeply and easily. The alternating low thread provides stability for fast, accurate driving.

The screws are coated with Stalgard finish to provide superior corrosion resistance. Fasteners coated with Stalgard finish typically show no red rust or other base material corrosion on significant surfaces even after 800 hours of 5% neutral salt spray exposure (ASTM B117).
