Your tools are spinning off straight peg hooks — the open design wasn't made for heavier hand tools that get grabbed and twisted every time someone reaches. A lock curve peg hook wraps around the tool shaft so it can't rotate or walk off. This 1-1/2-inch size handles mid-sized chisels, compact screwdrivers, and similar tools that need a tighter grip than a straight hook provides. 1-1/2-inch throat opening fits a wide range of mid-size hand tools. Lock-curve design locks tools in place under grab-and-go use. 1/4-inch rod fits standard pegboard holes. Zinc-plated finish resists corrosion in damp or unheated shop conditions.
