Concrete Masonry Wedge Anchors
Concrete Masonry Wedge Anchors are used to anchor and secure material and equipment to solid concrete masonry surfaces. Masonry anchors are also known as masonry bolts, concrete anchors, thru bolts, concrete bolts and anchor bolts. Wedge Anchors are available in Stainless Steel, Hot Dipped Galvanized, and Zinc Plated Steel varieties.
Wedge Anchors are used to install or fasten to concrete such as equipment, materials, generators, motors, pumps, pipes, strut, steel shapes, railing, benches, plastics or wood members. Wedge Anchors are installed into drilled holes, most often in concrete or other masonry materials. The non-threaded end is embedded into the hole and then struck to activate the expansion mechanism, which is fully utilized as the nut is tightened over the washer on the outside of the surface, on the material being fastened. The majority of the wedge anchor remains embedded in the solid masonry material being fastened to. Stainless Steel Wedge Anchors are used on oil rigs, docks, piers, walls or slabs. Wedge Anchors are available in 1/4"-20, 3/8"-16, 1/2"-13, 5/8"-11 and 3/4"-10, 7/8"-9 and 1"-8 sizes, with included Nut and Washer.
304 Stainless Steel Wedge Anchors:
(18% Chrome, 8% Nickel, .08% Maximum Carbon) – 18-8 Stainless refers to 300 series stainless steel. 303 and 304 Stainless are the most commonly listed grades, the standard grade for stainless steel fasteners. They are corrosion-resistant and durable. They are often used in marine applications in freshwater environments, but will not work as effectively in a salt water environment as 316 stainless. Stainless alloy resists oxidizing and rusting, however it can tarnish over time.
316 Stainless Steel Wedge Anchors:
(16%-18% Chrome, 10%-14% Nickel, .08% Maximum Carbon, 2.00% Maximum Molybdenum) – This grade of stainless steel is used and recommended for applications in severe, harsh or marine environments. Its corrosion resistance is greater than 18-8 stainless, which is why we recommend using 316 stainless steel fasteners for salt water application. It is important to remember that even the salt in the air near a body of salt water can do damage to dry applications, so 316 is the material of choice. Common applications of 316 stainless steel fasteners include use on boats, docks, piers, and pools.
Hot Dip Galvanized Steel Wedge Anchors:
Hot dip galvanizing is a process that adds a layer of corrosion resistance by dipping fabricated steel into a kettle containing molten zinc. The HDG process creates a tightly bonded alloy for superior corrosion resistance and harsh environment applications. HDG products must be used exclusively when applied, meaning that a plain zinc nut or stainless nut cannot be applied to an HDG bolt. HDG nuts are threaded slightly larger than other nuts to make room for the thickness of the galvanized coating.
Zinc Plated Steel Wedge Anchors:
Zinc plated steel is very common in the fastener industry. Zinc adds a layer of corrosion resistance to plain alloy steel. Clear zinc has a light, shiny color and blue zinc has a bright blue hue. Zinc plated steel is not suitable for extreme environment use, as it is not as resistant to corrosion as hot dipped galvanized.
