Product Feature

Ultra-fine threads: Offer metric micro-thread specifications such as M1.2, M1.4, M1.6, and M2, with fine pitches, specifically designed for threaded holes in watch plates, gear bridges, and miniature housings.

Precision countersinking: A strict 82° or 90° countersinking angle ensures that the head fully seats into the tapered countersink hole of the case or component after tightening, achieving a smooth and flush surface with no protrusions.

Full Dimension Inspection: Strict control over critical dimensions is implemented to ensure high consistency across batches, meeting the requirements for precision automated assembly or manual assembly.
