Hillman Fasteners 370042 Toggle Bolt 1/8x3 in Round Head 50pk

Product Description

The HILLMAN FASTENERS 370042 is a round-head toggle bolt packaged in a 50-count box, designed for fastening into hollow walls and ceilings where standard screws lack adequate holding surface. Each bolt measures 1/8 inch in diameter and 3 inches in length, constructed of steel with a zinc finish for corrosion resistance. The spring-loaded wing nut passes through a drilled hole, expands behind the wallboard, and clamps tight as the bolt is driven. These are a standard fastener for electricians, plumbers, and general contractors securing fixtures, brackets, conduit hangers, and equipment mounts to hollow substrates.

Toggle bolts in this size range are commonly used in light commercial and residential applications. Typical installations include mounting junction boxes, pipe straps, cable trays, light fixtures, and similar hardware to drywall, plaster, or hollow tile. The 1/8 inch diameter and 3 inch length make this bolt suitable for medium-duty loads where the wall cavity depth allows full wing deployment. The 50-count box format suits service van stock and small project runs.

Key Features

• Round head profile for flush or near-flush seating against the work surface
• 1/8 inch diameter x 3 inch length for medium-duty hollow-wall applications
• Steel construction with zinc finish for corrosion resistance
• Spring-wing toggle nut expands behind the substrate for secure anchoring
• 50-count box — practical quantity for service stock or single-project use

Compatibility

Designed as a standard-pattern round-head toggle bolt suitable for hollow drywall, plaster, and similar hollow-wall substrates requiring a 1/8 inch fastener.

Installation Notes

Toggle bolts are installed by drilling a clearance hole sized for the folded wing, threading the wing onto the bolt, and pushing the assembly through the hole until the wings spring open behind the substrate. Do not overtighten — excessive torque will strip the wall material or collapse thin board. Always verify that wall cavity depth is sufficient for the wings to fully expand before loading the fastener. Consult applicable building codes for load ratings when anchoring structural or safety-critical components.
