What are the common specifications of turnbuckle screws?

Screws are a kind of hardware product that we are familiar with. There are countless types of screws in our lives. Different types of screws have different designs and functions. I don't know if you have heard of turnbuckle screws. This is a relatively common type in our lives. This article will give you a brief introduction to what a turnbuckle is, what its functions are, and what its common specifications are!
  1. What are turnbuckles?
turnbuck screws or turnbuckle screws are their formal names. Turnbuckle screws are mainly divided into three types: cast malleable steel, ordinary carbon steel, and forged according to different process forming methods. It is mainly used to tighten the wire rope and adjust the tightness. Among them, type OO is used in situations where disassembly is infrequent, type CC is used in situations where disassembly is frequent, and type CO is used in situations where one end is frequently disassembled and the other end is infrequently disassembled.
2. Principle of turnbuckle screw
The reason why turnbuckle screws can be used to fix steel wires is inseparable from their special design. The turnbuckle is composed of an adjusting rod, a nut and a pull rod with left- and right-hand threads. The adjusting rod is also fixed with an anti-theft and anti-loosening device consisting of a cover plate, a fixed plate and a guide plate connected together with anti-theft and anti-loosening screws. When in use, a special matching sleeve must be used to unscrew the anti-theft and anti-loosening screws. It has a good anti-theft effect, is safe and reliable, has a simple structure, is easy to process, has low cost and is highly practical. It is especially suitable for power lines, especially as a positioning device for high-voltage iron tower poles.
3. Specifications and types of turnbuckle screws
 Because of the manufacturing environment of turnbuckle screws, we always use the tie rod to determine when calculating. The turnbuckle is a steel casting. When designing and calculating, only the corresponding parts can be calculated, but the specifications of the turnbuckle should be one level higher than the tie rod. The following are the specifications of tie rods and corresponding turnbuckles commonly used in steel structure design: tie rod turnbuckle Φ20M22, Φ24M27, Φ28M30, Φ30M32; various specifications of ordinary or high-strength turnbuckle screws, turnbuckle screws, open-body turnbuckles, open-body turnbuckles. Materials include: Q235B, No. 45 steel, 40Cr, 35CrMoA, Q345D turnbuckle screws, turnbuckle screws , flower orchid and so on.
