The wire is produced in-house, starting from raw coil rod and undergoing spheroidizing annealing, wire drawing, pickling, and skin pass. It then goes through quality inspection before being delivered to the screw production plant.
A screw begins its production with wire cutting, followed by cold forging to shape the head using precision-engineered dies.
For more complex shapes, multi-station cold heading systems are used to progressively form the part through a series of sequential dies and punches.
Tip forming involves cold forging or secondary machining to create functional screw ends. Sharp points allow easy penetration into wood, plastic, or thin metal.
Drill points enabling screws to cut through harder materials without pre-drilling.
Threading is done by rolling dies that cold-form precise threads without material loss. Thread types such as A, B, AB, UNC, UNF, triangular, and Hi-Lo, are selected based on material and application needs.
Each thread profile offers specific advantages in grip, torque, or compatibility with metal, plastic, or pre-tapped holes.
Heat treatment enhances screw hardness and tensile strength through controlled heating and quenching processes.
This ensures optimal performance in torque resistance, shear strength, and long-term durability for demanding applications.
To improve corrosion resistance and durability, surface coating can be applied upon request to enhances the performance of wear protection, rust resistance, and suitability for harsh environments.
A wide range of finishes is available, include zinc plating, black oxide, mechanical galvanizing, and organic coatings.
Washer and nut assembly is an optional process available upon request, added after threading to enhance the performance of load distribution, sealing, and installation efficiency.
Once the screws are completed, the products are carefully packed and prepared for ocean shipment.
To meet diverse market needs, a full range of packaging options is available, whether it's box, bag, bulk, plastic case, pail, or custom DIY kits, ensuring flexible and tailored solutions for every order.
