Anti-corrosion coating: four layers of high-performance coating makes the screws less prone to rust in outdoor construction, and the flat head wood screws are made of high-quality heat-treated steel.
Serrated Threads: Serrated threads on the head minimize plate separation, increase strength and ensure secure fastening.
Plummer head: Star drive wood screws make installation easier and come with a plummer head.
Dampening Knurled Shoulder: For faster, more secure installation. There are six non-slip bars under the head.
