Pull-out screws and imploding screws are two different types of screws that have significant differences in design and application.

Pull screw

The Tension control bolt is similar to an ordinary bolt and consists of a head, thread, bolt rod and washer. It is special in that the bolt rod is marked with scales that indicate the extent to which the bolt rod is stretched, thus ensuring that the pressure on the head and washer is properly distributed and avoids excessive distortion. The head of the pull-out screw is usually spherical, which is designed to reduce the possibility of loosening and turning. ? Pull-out screws are usually stronger than implosion screws, okay? Because its bolt rod is pressurized and stretched, the longitudinal axial stress increases, and the implosion screw is easy to break at the scale. one.

Implosion screw

Shear bolts are different from pull-out bolts in that they have only notches, not threads. Implosive screws are designed to break easily when subjected to shear forces and are often used in situations where rapid pressure release is required. For example, in some mechanical designs, implosive screws can automatically break when a certain pressure is reached, thus protecting the device from further damage.

Application scenario

Pull screw: Suitable for high-strength connection and preloaded nut is not easy to loosen the occasion, such as heavy machinery, building structures, etc.

Implosion screws: Often used in the need for rapid pressure release, such as safety valves, pressure relief devices, etc.

Historical background and theoretical basis

The design concept of the pull-burst screw emphasizes increasing the strength and stability of the bolt through stretching, while the design of the imploding screw is based on the shear force release mechanism. These two design concepts are suitable for different engineering requirements and safety requirements.

To sum up, the pull and implosion screws have their own unique design concepts and application scenarios, and the choice of which screw to use depends on the specific engineering needs and use environment.
