Turnbuckles

Baseline Bolt manufactures tie rod assemblies and Turnbuckles are offered as components of these assemblies. These are often used along with clevises. On one end, turnbuckles have right hand internal threads and on the other, left hand internal threads. As the turnbuckle is rotated, the tie rod assembly becomes 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 aren’t a stocked item, yet they can be made available within a couple of days. Turnbuckles come in both plain finish and hot dip galvanized finish; stainless steel and medium carbon steel.
