Turnbuckles are provided as components of tie rod assemblies that Portland Bolt 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.

Our new tie rod calculator will quickly determine rod lengths when given overall pin-to-pin dimensions of a tie rod assembly.

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.
