The Ultimate WOOD-TO-STEEL Screw is the Reamer Tek® Screw
Phillips flat reamer TEK® fasteners are durable wood-to-metal self-drilling screws suitable for a range of different applications. Available in bulk from All Points Fasteners Inc., these products are an ideal choice for HVAC equipment and ductwork installation. Use the order form on this page to request a quote on our Reamer screws, or contact our office directly with any questions you may have about these or other wood-to-steel screws in our inventory.
Distinguishing characteristics of our reamer TEK® screws include a pair of metal wings located on the screw shank. These wings are designed to ream out the wood, breaking off when they come into contact with 16 gauge or thicker metal. As a result, the screw thread is prevented from engaging prematurely into the timber. For this reason, reamer TEK® screws are often called wing-tipped screws.
All Points Fasteners sells reamer TEK® screws in several shank size and length configurations. Made of zinc-plated steel, our products are available in a #2 Phillips drive size with a #3 or #4 drill point. A finer thread count of 16, 20 or 24 TPI greatly reduces the risk of snapping by preventing the screw from rotating faster than the bit when drilling into thick materials.
At All Points Fasteners, we understand the need among contractors and OEMs for products that deliver reliable quality at a price that works for their budget. Our wood-to-steel screws and other fastening products are just one component of a complete assembly, but they’re an important one that can’t be compromised when it comes to reliability.
