Hexagon flange head tapping screws are also called; hex belt with self-tapping screws, hexagonal Phillips wood screws, cross recessed brain self-tapping screws, hex flange head wood screws, hex cross flange bolts. This is a nail designed specifically for wood and can be used in place of machine screws. Use a screwdriver to screw directly into the wooden component. Used to fasten a metal (or non-metal) part with a through hole to a wooden component. This connection is also a detachable connection. Simple, convenient and durable.

The hexagon head tapping screws have high anti-loose ability in combination and can be loaded and unloaded. In the small screw, its size, thread type, head type, tapping performance, high tensile force for engineering purposes, single piece, single side combination features are limitless. Hexagon head self-tapping material can be divided into carbon steel and stainless steel, among which carbon steel material is mainly C1018 medium carbon steel. The hex head self-tapping screws have a dense thread on the periphery, which not only helps to prevent slack, but also can be loaded and unloaded.
