How does a turnbuckle hook work?
A turnbuckle, also known as a bottlescrew, is a device consisting of two threaded eye bolts with opposite handed threads that are screwed into each end of a frame. When the central frame rotators, the eye bolts are prevented from doing so because the two bolts have opposite handed threads.

For example, a 1” x 6” turnbuckle body has an overall length of 8⅞”, but has an opening or “window” measuring 6”.
What is the difference between turnbuckle and rigging screw?

Which is better stainless steel or stainless steel turnbuckles?
For critical applications that require stainless turnbuckles, the drop forged turnbuckles will offer better long-term reliability due to the end fittings’ elongated design that reduces stress and their superior manufacturing process. Our turnbuckles are made from hot dipped galvanized steel and type 316 stainless steel.
