Dottie TB43DS Bolt, 1/4" 3" Square/Slotted Mushroom Head Toggle Bolt

For secure mounting of cameras, access control, and other monitoring or security devices in hollow walls, the Dottie TB43DS toggle bolt delivers dependable holding power. This 1/4" x 3" toggle bolt features a mushroom head that increases bearing area and an expanding butterfly anchor that spreads load across the back of drywall, plaster or hollow block—reducing pull-through and improving long-term stability. Made from carbon steel with a square/slotted drive and 20 TPI, the TB43DS balances strength with straightforward installation for technicians and installers. Because it expands behind the substrate, it supports light- to medium-duty loads such as dome cameras, small enclosures, conduit straps and signage commonly used in security, surveillance and IT mounting scenarios. Note that installation requires a larger pilot hole to accommodate the toggle mechanism, but the tradeoff is a much stronger anchor where solid backing is not available. Choose the Dottie TB43DS toggle bolt for reliable, professional-grade hollow-wall fastening—ideal for security, surveillance and low-voltage installations. Add to your next job kit and secure equipment with confidence.
