980Mpa Solid Concrete Expansion Zinc Plated Self Tapping Thread
1. Product Description
Wedge anchors are a type of concrete fastener designed for anchoring to solid concrete and come packaged with the correct number and size of nuts and washers Wedge anchors are available as zinc plated wedge anchors, hot-dipped galvanized wedge anchors, 304 stainless steel wedge anchors, and 316 stainless steel wedge anchor.
The wedge anchor is a commonly used type of anchor used for fastening into solid concrete because it provides exceptional holding values and is considered the most consistent of any mechanical type concrete anchor in terms of holding values. It is a versatile concrete anchor due to its wide range of diameters, lengths, and material types.
Installation
Drill hole in base material to your specified embedment depth. Debris from drilling must not interfere with the required embedment depth, the hole that you drill needs to be cleaned out with compressed air. Alternatively if the concrete thickness allows you can drill hole deep enough to accommodate the required embedment depth and the dust/debris from drilling. Assemble anchor so the nut is flush with the top of the anchor, place anchor into position through fixture and drive into the hole until the nut and washer are tight against the fixture.

3. Application
Wedge anchor extends into the tube sheet bore tube ends rolling leaving the tube wall expansion, plastic deformation, the diameter increases, the tube head completely fit the wall of the hole in the tube plate, tube sheet and forcing the elastic deformation . When the expander is removed, the elastic deformation of the tube plate desire restitution, and plastic deformation of the pipe end can not be recovered, the result is the tube plate and hugged the tube end, so as to achieve both the seal does not leak and are firmly connected purposes .
Wedge anchor use, you need to use the impact drill hammers on the fixed body corresponding to the size of the hole, then bolt, expanding loading hole, tighten the nut to the bolt, the expander, between the member and the fixed mounting swelling become one
