Built for heavy-duty concrete applications, the **CONFAST 3/8” x 3” Wedge Anchor** delivers a secure, long-lasting hold with its rugged steel construction and zinc plating for superior corrosion resistance.**** Designed exclusively for use in dry environments, these anchors are ideal for structural projects where reliability is critical—such as mounting shelves, equipment, or fixtures to concrete slabs, foundations, or beams. The wedge expansion design ensures a tight, vibration-resistant grip, making them perfect for demanding commercial, industrial, or DIY applications.
Each anchor comes pre-packaged with a matching nut and washer for quick, hassle-free installation. For best results, use an ANSI imperial bit matching the anchor’s 3/8” diameter to create a clean, precise hole. While durable for concrete, these anchors are **not recommended** for brick, block, or grout applications. With a 50-pack box, you’ll have ample stock for large-scale projects or frequent repairs. Trust CONFAST for professional-grade performance when every anchor needs to hold tight.
