UltraCon®Torx® Tamper-Resistant Masonry 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® tamperresistant 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).

Fastener Length and Diameter
The length of the UltraCon® fastener to be used is determined by combining the thickness of the attachment (A) with the desired depth of embedment in the masonry material (B). It is recommended that a minimum of 1" and a maximum of 1-3/4" embedment be used in determining fastener length. The diameter of the fastener and the depth of embedment affect pullout strengths. Application strength requirements and safety factors should be considered when determining the depth of embedment and fastener diameter.
Please reference the Performance Data chart on this page.
The correct hole depth (B & C) can normally be obtained by drilling the full length of this bit. In all cases, the hole must be at least 1/4" deeper than the depth of the fastener embedment. Normal safety precautions should be observed when drilling the holes to avoid electrical installations, other utilities and reinforcement bars.
The diameter of the drilled hole is also important to the performance of the UltraCon® masonry fastener. To provide the proper hole diameters, Elco® carbide-tipped drill bits are manufactured to closer standards than those called for in the American National Standard. Using Elco® carbide-tipped bits will help assure consistent performance and maximum pullout strength.
