A turnbuckle is a mechanical device used for adjusting the tension or length of cables, ropes, rods, or other tensioning systems. The size of the turnbuckle is determined by its dimensions, and in this case, “M20” refers to the metric thread size.

Turnbuckle can have different end types or end fittings to suit various applications and connection requirements. The end types typically include the following:

Common Uses of Turnbuckle M20

1· Tensioning of cables and wires in fences, railings, and suspension bridges.
2· Supporting and adjusting the tension of sails in sailboats.
3· Tightening guy wires for telecommunications or radio towers.
4· Maintaining tension in overhead lines for electricity distribution.
5· Adjusting tension in netting and other types of fabric or mesh.

 

Turnbuckle Forged vs Malleable

Turnbuckle is a kind of rigging hardware which is widely use. As you can see, there are two types which are forged and malleable steel types. The two have the same size and configuration, but the production process and raw materials are different.

First of all, malleable steel turnbuckles are cast by Masteel. And the forged type turnbuckle is forged from round carbon steel. Forging can eliminate defects such as as-cast porosity produced in the metal smelting process, while preserving the complete metal flow line.

Therefore, the mechanical properties of the forged turnbuckle are better than those of the malleable steel turnbuckle with the same specification. But in terms of price, DIN 1480 Malleable turnbuckle has a greater advantage. So we can make the right choice from the combination of performance and price when purchasing.
