You need a lifting point, a tie-down anchor, or a quick attachment point on a flat bar or post — and you don't want to weld or drill a permanent hole. Or you're setting up a temporary rig and need something that goes in fast and comes out clean. Eye bolts are the most common light-duty attachment point hardware and every workshop and truck should have a selection. 5/16-inch by 2-1/2-inch zinc-plated eye bolt with hex nut. The 5/16-inch diameter is the sweet spot for light-to-medium loads — enough working load limit for typical garage, shop, and jobsite rigging without the oversize cost and weight. The 2-1/2-inch shank length gives you enough penetration into wood or thread engagement in metal to develop the full working load without bottoming out or pulling through. Zinc plating provides a Stocked at Crofton Lumber and Akron Lumber.
