Thicker walls — whether from multi-layer drywall, plaster over gypsum, or deeper exterior assemblies — need longer hardware to thread out fully and engage the toggle properly. These 3-inch 3/16-inch toggle bolts give you the extra reach while maintaining the medium-duty load capacity (up to 50 lb per bolt) that distinguishes 3/16-inch from 1/4-inch hardware. The 3/16-inch diameter is the sweet spot for bathroom grab bars, support railings, and shelving in commercial or multifamily work where the walls aren't standard depth. Longer 3-inch bolt handles deeper assemblies without stepping up to a heavier diameter that would over孔 the mounting surface. Zinc-plated steel, round head flush finish, 50-piece box. Standard on multifamily and commercial finishing work across northeast Nebraska and no Stocked at Crofton Lumber and Akron Lumber.
