A bolted joint is one of the most common elements in construction and machine design. It consists of a male threaded fastener (e. g., a bolt) that captures and joins other parts, secured with a matching female screw thread. There are two main types of bolted joint designs: tension joints and shear joints.
Slip-critical joint, from structural engineering, is a type of bolted structural steel connection which relies on friction between the two connected elements rather than bolt shear or bolt bearing to join two structural elements.
A bolted joint is a mechanical joint which is the most popular choice for connecting two members together. It is easy to design and easy to procure parts for, making it a very popular design choice for many applications. Advantage: Joints are easily assembled/ disassembled by using a torque wrench or other fastener tooling. [7]
40 tonne-force × 0.6 (to change force from tensile to shear) = 24 tonne-force. When working with a riveted or tensioned bolted joint, the strength comes from friction between the materials bolted together. Bolts are correctly torqued to maintain the friction. The shear force only becomes relevant when the bolts are not torqued.
The stress and shear in a rivet are analyzed like a bolted joint. However, it is not wise to combine rivets with bolts and screws in the same joint. Rivets fill the hole where they are installed to establish a very tight fit (often called an interference fit). It is difficult or impossible to obtain such a tight fit with other fasteners.
Bolted joint in vertical section Screw joint. The distinction between a bolt and a screw is poorly defined. The academic distinction, per Machinery's Handbook, [3] is in their intended purpose: bolts are designed to pass through an unthreaded hole in a component and be fastened with the aid of a nut.
Additionally, shear-pins are frequently used in anti-tank mine fuzes, to prevent them from being triggered by much lighter, non-target vehicles such as motorcycles. Typically, the shear-pin in an anti-tank mine is designed to snap (and release the spring-loaded firing pin) when a weight in excess of 1500 kilograms is applied to the pressure plate.
In critical fastener joints, embedment can mean loss of preload. Flattening of a surface allows the strain of a screw to relax, which in turn correlates with a loss in tension and thus preload. In bolted joints with particularly short grip lengths, the loss of preload due to embedment can be especially significant, causing complete loss of preload.
