Hillman Fasteners 41427 Toggle Bolt 3/16x4 in 8pk

Product Description

The HILLMAN FASTENERS 41427 is a round head toggle bolt designed for fastening into hollow walls and ceilings where standard screws lack adequate holding surface. The 3/16-inch diameter by 4-inch length configuration suits medium to heavy anchoring tasks in drywall, plaster, and similar hollow-cavity substrates. Each pack contains 8 bolts, supplied in a large clamshell retail pack for jobsite or shop storage. Electricians, plumbers, and general contractors reach for toggle bolts when securing conduit hangers, junction boxes, pipe straps, and fixtures to hollow-wall surfaces where a solid stud or joist is not accessible.

This toggle bolt is suited for residential and light commercial interior applications. Common install scenarios include mounting brackets, hangers, shelving supports, and electrical or plumbing accessories to hollow drywall or plaster walls and ceilings. The round head profile seats flush against flat mounting surfaces, distributing load evenly across the wall face. The spring-loaded wing anchor spreads behind the wall cavity to create a secure mechanical grip.

Installation Notes

Toggle bolts are installed by a qualified tradesperson or knowledgeable installer following applicable building and mechanical codes. Drill a hole sized to allow the collapsed toggle wings to pass through, then insert the bolt and allow the wings to spring open behind the wall surface before tightening. Never overtighten — snug the bolt until the head seats firmly against the fixture and wall face to avoid crushing the substrate. Verify that the selected bolt length and diameter meet the load requirements of the application before installation.
