Deep wall cavities and thick wall assemblies call for longer hardware — a bolt that's too short won't thread out fully, and one that bottoms out before the toggle seats is useless. These 4-inch 1/8-inch toggle bolts cover the case where standard lengths fall short and you're dealing with deep plaster, multi-layer drywall, or cavity depths that go beyond what commodity toggle bolt lengths handle. 4-inch thread length gives you the reach for deep wall assemblies while the 1/8-inch diameter keeps you in the light-duty range for loads up to 20 pounds per bolt. Zinc-plated for indoor use. Round head for flush installation. 50-piece box is sized for the contractor who needs enough of one size to cover multiple deep-cavity situations on a single job. Standard on historic remodel and deep-wall ass Stocked at Crofton Lumber and Akron Lumber.
