Description
When standard wall plugs aren’t enough, the Unicrimp QWEBF8 Bullfix Extra provides the confidence you need for demanding installations. Specifically engineered for standard 12.5mm to 16mm plasterboard, these fixings utilize a patented “smart wing” design that hooks securely behind the board, distributing weight across a larger surface area to prevent failure.
Ultimate Strength & Reliability:
-
Unrivalled Load Capacity: Capable of supporting up to 133kg (shear load), making them some of the strongest plasterboard fixings on the market.
-
Patented Smart Wings: The wings are designed to open fully in a cavity as shallow as 20mm. If the wings cannot deploy, you literally cannot drive the screw in—providing a “fail-safe” guarantee that the fixing is secure.
-
Specialized for Stud Walls: While the Universal Bullfix range works on dot-and-dab, the Extra (QWEBF series) is optimized for stud wall cavities where maximum mechanical grip is required.
-
Vibration Resistant: Unlike metal self-drill fixings, Bullfix will not work loose over time or damage the plasterboard core through vibration.
Quick 5-Step Installation:
This starter kit is designed for immediate use, containing everything but the drill itself:
-
Drill: Use the included 20mm bit to create a clean hole.
-
Insert: Push the collar into the hole.
-
Push: Slide the fixing into the collar.
-
Tap: Tap flush to the wall to deploy the wings.
-
Fix: Screw your bracket or fixture directly into the unit.
