This white Ruspert concrete screw is a heavy-duty fastener specially made for fixing fixtures on concrete and brick walls.
It adopts hardened carbon steel as raw material to guarantee enough hardness to cut into dense cement masonry. The surface uses professional White Ruspert coating, which consists of zinc bottom layer, chemical conversion film and baked white ceramic top coat tightly combined together. This dense protective barrier effectively blocks moisture, salt and acid rain erosion, suitable for long-term outdoor exposure. The whole coating process keeps temperature under 200℃, so the screw’s hardness and drilling performance will not be damaged during treatment.
Unique high-low staggered thread design can carve stable spiral grooves inside concrete after screwing in. Thread teeth lock firmly into cement texture, so the screw won’t loose or drop off under long-time load and vibration. One-piece hex flange head replaces independent flat washers, cutting down construction steps for installers. Sharp tip guides the screw smoothly into pre-drilled small holes without cracking brick and concrete surfaces.
Different from ordinary galvanized concrete screws, White Ruspert finish owns uniform white appearance that fits white exterior wall panels and light decorative materials, no ugly metal color exposed outside finished walls. Every production batch will go through salt spray, pull-out load and hardness inspection before delivery, matching exterior construction hardware standards. Contractors can order customized length and coating color according to their wall renovation and outdoor fixing projects.
