Sumo Max 1 FK Speed
Screw anchor / concrete screw
The TOX Sumo Max 1 FK Speed concrete screw, made of galvanized steel with a flat head, is the latest addition to our popular Sumo Max 1 screw anchor series. What makes this variant special is its small drill diameter of just 6 mm for fast drilling progress and significant time savings, as well as its low embedment depth, preventing reinforcement hits. This concrete screw is ideal for secure yet ultra-fast fastening of cable ducts, suspended ceilings, and thin profiles in concrete and solid brick.
The Sumo Max 1 series - available in various lengths and head shapes and optionally in A4 stainless steel or galvanised steel - is suitable for both adjustable and demountable as well as permanent fixings.
