Wedge Anchors are a non-bottom bearing, wedge-style expansion anchor for use in solid concrete or grout-filled concrete masonry. A one-piece clip ensures uniform holding capacity that increases as tension is applied. Installation is simple, utilizing standard hole sizes equal to the anchor bolt diameter. Wedge Anchors are among the most common and economical anchoring option for existing concrete. Available in 304 stainless steel or 316 stainless steel. 316 stainless steel fasteners are commonly used in applications that require general atmospheric corrosion resistance, such as chemical and food processing equipment. 316 stainless steel has a higher corrosion resistance than 18-8 or 304 stainless steel.
