Manufacturing Process&Working Principle
The Quick-Thread Machine Screw ALSA1110001 is manufactured through a controlled and repeatable process to ensure consistency and performance:
1.Cold Heading Forming
The cup head and stepped shaft are formed in one process,ensuring excellent concentricity and strength.
2.Precision Thread Rolling
The quick-thread profile is rolled(not cut),improving surface hardness and increasing fatigue resistance.
3.Stepped Shaft Processing
The stepped section enables accurate positioning and controlled load transfer during assembly.
4.Surface Treatment–Blue Zinc Plating
An environmentally friendly blue zinc coating is applied to improve corrosion resistance while meeting international environmental standards.
Working Principle:
The stepped shank guides the screw into the correct position,while the quick-thread engages rapidly with the internal thread,delivering strong holding force with fewer rotations than conventional machine screws.
