Hillman Fasteners 370096 Toggle Bolt 3/8x4 in Steel 25PK

Product Description

The HILLMAN FASTENERS 370096 is a round head toggle bolt designed for fastening into hollow walls and ceilings where a standard screw or anchor cannot achieve adequate holding strength. Each bolt pairs a machine screw with a spring-loaded wing nut that collapses for insertion and expands behind the substrate once pushed through the drilled hole. The fastener body is steel with a zinc finish for corrosion resistance. This box contains 25 bolts at 3/8 x 4 inches, making it a practical quantity for commercial or multi-unit residential work.

Toggle bolts in this size range are commonly used by electricians, HVAC technicians, and general contractors to suspend conduit hangers, junction boxes, ductwork supports, light fixtures, and similar loads from drywall or plaster ceilings. The 3/8-inch diameter and 4-inch length suit medium to heavy-load applications in hollow wall assemblies of typical residential and light commercial construction thickness.

Key Features

• Round head profile provides a clean seating surface against the wall or ceiling face
• Spring-loaded toggle wing collapses for insertion and locks behind hollow substrate
• Steel construction with zinc finish for corrosion resistance
• 3/8 x 4 inch size suits medium to heavy suspension loads in hollow assemblies
• 25-count box quantity reduces per-job procurement trips

Compatibility

Designed as an OEM-style replacement and standard-spec toggle bolt for use in hollow drywall, plaster, and similar hollow wall or ceiling substrates requiring a 3/8-inch diameter toggle fastener.

Installation Notes

Toggle bolts are installed by licensed tradespeople including electricians and HVAC technicians working under applicable building codes. Drill a hole sized to allow the collapsed toggle wing to pass through cleanly, insert the toggle with the bolt attached, and tighten until the wing seats firmly against the back of the substrate. Do not overtighten, as this can crack drywall or pull the toggle through the face. Always verify that the substrate and toggle size combination meets the load requirements for the specific application before installation.
