Crown Bolt - No. Eye bolts are externally threaded fasteners featuring loops that secure cables, wires, and chains to assist with vertical lifting. Reducing the flight pitch reduces the capacity. Parts feature a roughly 110lb weight capacity Acceptable clamp load is typically 75% of proof load. Description: GN 581.5 swivel lifting eye bolts offer a high load carrying capacity and are tested to meet high safety standards. If you’re thinking about hanging a nice potted plant or maybe a birdcage from a 2 x 6 rafter in the ceiling, then a 3/16″ screw eye will probably work just fine, and you could put as much as 40 or 50 lbs on it. Collared eye bolts can take reduced loads at angles but only in the plane of the eye. So, if you run a ball scrtew with a dynamic load equal to it’s dynamic capacity, you may actually not get the life of one million revs. The stronger the screw, the more weight it will be able to hold. Screw eyes are designed for vertical hanging from wood. In spite of their widespread use, limited information is available regarding load carrying capacity and rigidity of real size cases with RTA corner joints. For example, a 1/2 pitch screw carries 1/2 the capacity of a full pitch screw at the same level of trough loading and speed. Do not use to lift loads as this might cause the hook to bend and the load to drop. In case you didn’t already know, an eye bolt’s “rated capacity” describes how heavy of a load a single eye bolt can support when the load is angled at 0 degrees through the eye bolt’s shank. Lifting Eye Capacities (WLL - Working Load Limit) are available online from 95kg all the way up to 30 tonnes dependant on model types.
