The Throughbolt Anchor, also known as the can-through bolt, is a bolt that expands tightening of the nut on a taper stud. These bolts are usually Zinc Plated either in White or Yellow or Stainless Steel 304Gr and come in a variety of diameters and lengths


 


Selection of the right length?


This is quite simple. We add the thickness of the material that needs to be fastened, the minimum embedment and the thickness of the nut and washer.


 


How do I space my anchors?


The material (usually concrete) in which the Strike Anchors are installed are subjected to forces by the anchors. Installation of these anchors, too close to each other, can cause these forces to interact and consequently lowering the holding power of the anchors. As a thumb rule, the concrete anchor industry has established a minimum standard of ten (10) anchor diameters for spacing between anchors and five (5) anchor diameters from an unsupported edge. When vibration or sudden impact are part of the load condition, spacing between anchors should be increased.
