The Series GN 581 swivel-lifting eye bolts come in metric sizes. The bolt’s ring is forged and annealed steel with a special bright pink powder-coated finish that changes color to indicate exposure to high temperatures. The threaded socket-head bolt is made from European standard 10.9 grade steel, and the hex-key cover plate is zinc-plated steel.
These eye bolts are mounted in a bearing and can be rotated. The ring can be positioned in the direction of the load for optimum strength. A special cap screw cannot be removed from the ring.
