Turnbuckles are provided as components of tie rod assemblies that Fastindo Wiratama manufactures and are often used in conjunction with clevises. Turnbuckles possess right hand internal threads on one end and left hand internal threads on the other. By rotating the turnbuckle, the tie rod assembly is drawn tight.


Availability

Turnbuckles are not a stocked item but are available within a day or two. Turnbuckles are provided in both plain finished and hot dip galvanized medium carbon steel as well as stainless steel.
