Use steel washers to fill the space of the unthreaded part of the shank, but the thickness of the steel washer must not exceed one thread pitch. The applied load (F) for lifting appliances can be determined by any suitable calculation facility including CalQlata's lift rigging calculator. Always insure hoist ring is properly torqued to required value. （The bolt is subjected to 200 kgf loads in the same way. Forged eye bolts come complete with a drop-forged eye, and feature good hardness and strength can be used in heavy-duty lifting applications. Angular Loading of Eye Bolts and Rated Capacity. Make sure load is evenly distributed. • The bolts are subjected to shear or tension loading. VRS High Capacity Eye bolts can be adjusted to the direction of pull. If the shoulder is not completely flush, it can only be used for vertical lifts, equal to regular eye bolt. Then they are anodized, hot-dip galvanised, or plated (gold, zinc, or tin) even phosphate coating finishes, which can effectively prevent corrosive substances from coming into contact with the carbon steel, and improve corrosion resistance. Always apply load to eye bolt in the plane of the eye. 5 LOAD CAPACITY: NUMERICAL APPROACH This section describes the details of the FE simulation and the load capacity estimation of same pad eyes, which have a SWL of 3.25 tons.
