ELCO UltraCon® Concrete Screws
UltraCon® Masonry Fasteners High Performance in a Wide Range of Applications
The UltraCon masonry fastening system from Elco Construction Products offers optimal performance in a wide range of masonry applications. Cold formed fasteners, precision‑cut Elco carbide drill bits and high‑quality installation tools all work together to provide excellent pull-out and shear values. All components of the system are manufactured to strict quality standards to ensure consistent, trouble-free installation and in-place performance. UltraCon fasteners are the optimal solution for concrete, brick or hollow block to attach electrical boxes and clips; wood headers, plywood, or furring strips; exterior insulation systems and more.
Increased Size for Increased Strength |
| The new 5/16" diameter UltraCon fastener provides increased shear and tensile strength to meet the needs of more demanding applications. |
Increased Size for Increased Strength |
| UltraCon fasteners from Elco Construction Products are coated with Stalgard finish to provide superior corrosion resistance. Fasteners coated with Stalgard® finish typically show no red rust or other base metal corrosion on significant surfaces even after 800 hours of 5% neutral salt spray exposure (ASTM B117). |
Experience Matters |
| Elco Construction Products has been manufacturing fastening systems for concrete in the U.S.A. since 1980. Unlike competing masonry fasteners, only UltraCon fasteners are coated with Stalgard finish. To assure quality on your next masonry application, choose the UltraCon masonry fastening system manufactured by the company known for quality – Elco Construction Products. |

INSTALLATION |
| The UltraCon masonry fastening system consists of the UltraCon fastener and installation tool plus an Elco® carbide-tipped drill bit. Consistent performance and maximum pullout strength can be assured only when all three elements of the system are properly used |
|
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. UltraCon fasteners come in three diameters: 1/4", 3/16", and 5/16". 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. For assistance, contact your Elco distributor or Elco Construction Products |
|
Hole Depth An Elco® carbide-tipped drill bit is supplied with each box of UltraCon fasteners. 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. |
|
Hole Diameter The diameter of the drilled hole is also important to the performance of the UltraCon masonry fastening system. 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 fastener performance and maximum pull-out strength. |
|
A = attachment thickness B = UltraCon embedment (min. of 1", max. of 1-3/4") A + B = UltraCon anchor length B + C = Hole depth (must be at least 1/4" deeper than UltraCon embedment) |
