5/16" Forged Eye & Eye Stainless Steel Turnbuckle - Type 316

This forged eye and eye turnbuckle is constructed from Type 316 stainless steel for superior corrosion resistance in marine and high-moisture environments. Designed in the traditional U.S. pattern with a hex body, it features elongated eyes for improved strength and easier attachment. Built to meet ASTM F1145-92 Type 1, Class H dimensions, it delivers reliable performance in demanding tensioning applications.

Please Note: Turnbuckles are intended for straight or in-line pulls only. Loading at an angle will significantly reduce capacity and may result in failure.
