Overview
Bullfix's plasterboard fixings come 6 to a pack and are built around a wing-and-collar design rated to hold up to 255 lbs on standard 1/2 and 5/8 inch drywall, using a patented lock that stops the screw from seating until the wings are fully deployed.
The pitch is confidence over guesswork: because the screw physically can't be driven home until the anchor has opened behind the wall, there's a built-in check that it worked. The kit bundles the anchors, collars and No. 10 screws for a five-step install, and it's designed to fit in as little as a quarter inch of cavity, tighter than most toggle bolts need.
- 6-pack of plasterboard fixings
- Holds up to 255 lbs on standard drywall
- Fits cavities as shallow as 1/4 inch
- Complete kit with collars and No. 10 screws
Who it's for
Aimed at homeowners and installers hanging flat or tilt TV mounts, heavy mirrors, AC units, shelves, or coat and drying racks on drywall, insulated walls or tight stud cavities. Less relevant if the wall cavity is already deep enough for a standard toggle bolt.
Pros and cons
- Patented lock confirms the wings have deployed before the screw seats
- Rated up to 255 lbs on 1/2 and 5/8 inch drywall
- Needs only 1/4 inch of cavity
- Kit includes anchors, collars and screws
- Only 6 fixings per pack
- Weight rating is specific to standard 1/2-5/8 inch board
- No stated ability to remove and reuse
Performance notes
The wide wing and collar spread the load across a larger area behind the board than a plain screw-in anchor, and Bullfix says this keeps the fixing from working loose over time the way lighter anchors can. It's built to work on stud walls and insulated drywall as well as plain plasterboard, needing only about a quarter inch of clearance behind the board.

Frequently asked questions
How do I know a Bullfix anchor has opened correctly?
The patented wing design physically prevents the screw from going in until the wings are fully deployed behind the wall, so if it screws in, it has locked.
How much weight will Bullfix hold?
Up to 255 lbs on standard 1/2 inch and 5/8 inch drywall, according to the listing.
Does Bullfix work in a tight wall cavity?
Yes, it's designed to need only about 1/4 inch of cavity, where many toggle bolts need 1 to 2 inches of depth.
