Screw Type Expansion Anchor Bolts, also known as expansion bolts or expansion anchors, are a type of fastener used to secure objects to concrete or masonry surfaces. These bolts consist of a threaded anchor body with a tapered end and a nut or washer.

The installation process involves drilling a hole into the concrete or masonry surface, inserting the anchor bolt into the hole, and tightening the nut or washer to expand the anchor and create a secure connection. As the nut or washer is tightened, the tapered end of the anchor bolt expands against the walls of the hole, providing a strong grip and preventing the bolt from pulling out.

Screw type Expansion Anchor Bolts are commonly used in construction, carpentry, and other applications where a secure attachment to concrete or masonry is required. They are available in various sizes and materials, such as steel or stainless steel, to suit different load requirements and environmental conditions.
