Compression bolts, also known as tension bolts, are designed to be used as anchors and fastening components to join structural components in construction projects. They are used mainly for pre-cast concrete wall construction.

Compression bolts usually have a hexagonal head with a threaded shank and nut. The nut is tightened to draw the threaded shank through a pre-drilled hole in the structural members, which is then held in place by the nut. The shank has a shoulder that rests against the inner face of the structural parts to prevent the nut from turning while being tightened. The shoulder also serves to aid in the transmission of the bolt loads to the structural components.

Compression bolts are an excellent choice for use in many types of construction projects because they provide the strength of a continuous block or plate of steel without the cost and complexity of welding. Additionally, the bolts are adjustable, easy to install, and require less maintenance than welds.

In order to ensure that a compression bolt is properly installed, the proper torque must be used when tightening the nut. Over-tightening can cause the bolt to break, while under-tightening can cause the bolt to loosen. Properly tightened compression bolts can provide a strong and reliable connection for many years.
