Ronstan Threaded Eye 1/4" UNF Thread Ronstan rigging fittings have rolled external threads for maximum strength and reliability - unlike cut threads, the stainless steel bar is formed up and down to create a thread with the grain remaining unbroken and flowing the full length of the thread. Threads are UNF (Unified National Fine), short pitch threads for fine adjustment and reduced adjustment effort Compatible with Type 10 turnbuckles. Type 10 closed body turnbuckles have a sleek, modern profile with no sharp edges. They are easily adjusted by turning the unique adjustment nut, which is free to rotate within the sleeve on the turnbuckle body, and are secured with a quick turn on the locking nut. A sight hole is provided in the body to verify adequate thread engagement. With fine thread and single end adjustment, Type 10 turnbuckles are much easier to adjust than conventional turnbuckles, and the use of dissimilar but compatible metals for the threaded components avoids the risk of thread seizure. Features: Threads are UNF (Unified National Fine), short pitch threads for fine adjustment and reduced adjustment effort. Compatible with Type 10 turnbuckles
