Hexagonal wood screws

Product Introduction: 

Hexagonal head self-drilling screws are a new type of high-efficiency riveting fastener. 

The self-drilling screw has a drill-shaped or pointed end for riveting. 

When riveting connected parts with self-drilling screws, 

no auxiliary processing is required on the surface or inside of the connected parts. 

The self-drilling screw can directly drill, tap, and tighten in one quick and easy operation.

Product Features:

 Its key function is to increase the contact area, disperse pressure, and prevent crushing of soft materials.

 The torsion spring of the spring washer essentially applies force to the nut after tightening, 

increasing the sliding friction between the nut and the bolt!
