Fasteners are a class of industrially based components used to securely connect or fasten two or more objects mechanically. They form removable or permanent connections by applying clamping forces to overcome the separating action of external forces.
Common types include screws, bolts, nuts, washers, rivets, pins, etc. Their core value is to achieve structural assembly integrity, load transfer and safety. From microelectronic devices to heavy bridges, virtually every industrial product relies on fasteners to create physical connections.
General Fasteners
Carbon Steel Electro-galvanized and then chrome passivated for basic corrosion protection and economy.
Stainless Steel Fasteners
Solution annealed austenitic material with passivated surface for rust free coating.
High Strength Fasteners
Alloy steel quenched and tempered for strengthening, Dacromet coating for corrosion resistant load bearing.

Products Process
Preparation of raw materials
Selected wire or bar materials such as carbon steel, stainless steel or alloy steel are preliminarily shaped by cold heading or hot heading process.
Molding process
Fasteners are extruded through multi-station dies to produce heads and rods, rolled to produce thread reinforcement, and heat-treated to optimize mechanical properties.
Surface Finishes
Fasteners are galvanized by electro-galvanizing, hot-dip galvanizing, Dacromet or phosphating to improve corrosion resistance.
Quality Inspection
Through-gauge inspection screw size, hardness test, corrosion resistance test, torque test.
Packaging & Shipping
Rustproof packaging as per customer's requirement, such as VCI paper, vacuum bag, etc. with specification and material information.
Our product range includes:
Materials: Carbon steel / Mild steel / Structural steel / Stainless steel / Aluminum / Copper, etc.
Forms: Sheets / Profiles / Tubes / Round bars / Flat bars / Square bars, etc.
