Dottie DOTW38-300 Fully Threaded Wedge Anchor 3/8 Inch Diameter 3 Inch Steel Zinc Plated

Product Description

The DOTTIE DOTW38-300 is a fully threaded wedge anchor designed for secure, permanent fastening into concrete and masonry. This anchor is built for trade professionals including electricians, plumbers, HVAC technicians, and general contractors who need a reliable fastener for structural and mechanical installations. The 3/8 inch diameter and 3 inch overall length make it well suited for medium-duty applications where a strong, vibration-resistant hold is required in concrete slabs, walls, and foundations. The anchor features a 1-7/8 inch thread length with a 3/8-16 UNC thread pattern, giving installers a full grip range for nuts and washers during tightening. Zinc plating provides corrosion resistance, making this anchor appropriate for indoor and protected outdoor environments. The fully threaded design allows greater flexibility in embedment depth and nut positioning compared to partially threaded anchors. To install, drill a 3/8 inch hole into the concrete substrate, vacuum or blow out the hole to remove dust, insert the anchor, and tighten the nut to the specified torque. The wedge mechanism expands as the nut is torqued, locking the anchor tightly against the sides of the drilled hole. Steel construction ensures the anchor can handle tensile and shear loads common in mechanical, electrical, and plumbing support applications. This fastener is compatible with standard 3/8 inch hardware including hex nuts, flat washers, and lock washers. The DOTW38-300 is a straightforward, dependable concrete fastener for everyday trade and construction work.

• Fully threaded 3/8-16 UNC design allows flexible nut positioning and full thread engagement
