With the Spit nyl universal nylon plug, you achieve dependable anchoring across solid and hollow building materials such as concrete, solid brick, sand-lime brick, and aerated concrete. Thanks to the rimless 12X60 mm design, you can sink the plug deep into the 12 mm drill hole for clean push-through installations and flush finishes. The high-grade PA6 polyamide construction resists distortion and prevents spinning when driving in 8 mm to 10 mm screws. This gives you the solid hold needed to mount heavy shelving, cabinets, wall structures, and pipe brackets with complete confidence.
