Large diameter concrete screws are fully threaded and range from 1/4" to 3/4" in diameter. These features create a strong hold with more engagement from the threads. The increased diameter size means you can get higher load strength, which makes large diameter concrete screws ideal for applications where the thickness of the concrete requires a shallower hole or when the screw needs to be placed further from an unsupported edge.
Large Diameter Tapcons are a fast and convenient alternative to Wedge Anchors. They are easy to install because of the all-in-one hardware design, with no need for nuts and bolts. Additionally, like other concrete screws, LDT’s are removable if temporary application is required.
Large diameter concrete screws are offered in a variety of finishes, including zinc, galvanized, stainless steel, and envirex coated.
Zinc-Plated Steel - These concrete screws feature a shiny surface best for interior applications in a dry environment and carry a low level of corrosion resistance.
Hot Dip Galvanized - These concrete screws have a dull surface, are best for exterior, wet, and hot applications, and carry a medium level of corrosion resistance.
Stainless Steel – We offer three types of stainless steel concrete screws, which are all great options for corrosion resistance and used for exterior and interior applications. Type 304 Stainless Steel is the most affordable of the stainless steel concrete screws. Type 316 Stainless Steel is chlorine resistant and ideal for offshore and marine applications. Type 410 Stainless Steel is the hardest of the stainless steels and it's resistant to hot gases and steams but is not as corrosion resistant as 304 or 316 stainless.
Envirex Coated Steel – These concrete screws are suited for exterior applications and are compatible with most treated lumbers.
Large diameter concrete screws are offered in a huge variety of lengths, starting at 1 3/4" and ranging up to 15”. We offer hex head concrete screws, Phillips flat head screws, and star drive screws (Torx drive screws) to ensure you find the screw that you need. We partner with reliable, high quality manufacturers like ITW Read Head and Simpson Strong-Tie and most products are ready to ship within 24 hours.
