Contractors and DIYers, these Wej-It wedge anchors are seriously heavy-duty! Made from 304 stainless steel, they provide way better corrosion resistance than galvanized or zinc-plated anchors - perfect for outdoor applications or humid environments. The 3/8\ diameter with 2-3/4\ length gives you a 1-3/4\ minimum embedment depth, and they're rated for 3,850 lb ultimate tensile strength in 4,000-psi concrete. The clip has large dimples that provide extra traction to reduce slippage, especially in lightweight concrete. Installation is straightforward: drill a hole matching the anchor diameter, insert the anchor, and tighten the nut to expand the clip for a secure hold. They meet strict Federal Specifications QQZ-325Z and GSA FFS-325 standards, plus Miami-Dade NOA compliance. The safety shoulder above the clip provides extra support under severe strain, and the dog point prevents damage during installation. Remember to use only one-fourth or less of the maximum values for safe working loads as required by local regulations. Whether you're mounting heavy equipment, structural elements, or anything that needs serious holding power in concrete or solid masonry, these anchors deliver reliable performance you can count on.
