Simpson 1/2" x 4-1/4" Wedge Anchor

The Simpson 1/2" x 4-1/4" wedge anchor is a type of mechanical expansion anchor used to fasten heavy loads to concrete, masonry, and other solid base materials. The anchor consists of a steel body with a threaded end, a nut, and a washer.

 The threaded end is inserted into a pre-drilled hole and then tightened with a wrench, causing the anchor to expand and wedge tightly against the sides of the hole. The nut and washer are then used to attach the load to the anchor. This type of anchor is commonly used in construction for securing steel columns, heavy machinery, and other large structures to concrete floors or walls.
