Product Basics

Self-tapping screws cut their own matching internal threads as they are driven into base materials, which saves you the extra step of pre-tapping holes for most thin sheet metal, plastic and wood applications. We produce all these screws on our in-house cold heading lines with full thread rolling process, so each batch comes with clean, full tooth profile and consistent tightening torque. You will barely face cam-out or thread stripping issues under normal installation.

We keep over 200 standard sizes in stock for fast dispatch. For special project needs, we also support custom lengths, special head shapes and step shank structures based on your drawings or original samples. Most of our repeat clients place monthly bulk orders after they pass the first sample testing.
