A hanging job that requires going into the ceiling — fans, planters, decorations — and the wrong hook size means either it bends under load or it doesn't engage enough thread in the anchor to hold. This 3/8-inch by 10-inch ceiling hook gives you the diameter for substantial load capacity and 10 inches of thread length to engage deep into the structural ceiling member or a heavy-duty ceiling anchor. The 3/8-inch shank won't spin out the way smaller hooks do when you're applying torque to tighten the ring. Zinc plating handles the corrosion from humid air in unfinished basements and outbuildings where ceiling hooks see the most use. The threaded shank format lets you turn it directly into a predrilled hole in a wooden ceiling member, or use a lag shield anchor in concrete and masonry ceiling Stocked at Crofton Lumber and Akron Lumber.
