Bimetallic screw
The bimetallic screw from Lianzhong Industry Co., Limited combines two distinct metals to optimise strength, wear resistance, and corrosion protection for industrial fastening. The design typically pairs a carbon steel core with a stainless steel or hardened alloy outer layer, achieving a balance of toughness and surface durability. These screws are engineered for heavy-duty applications where standard fasteners fail under stress or environmental exposure.
Precision threading ensures a secure grip, while the bimetallic construction resists galling and seizing in high-friction environments. Typical industry standards for such screws include ISO 4017 for hex head screws and ISO 7045 for countersunk variants, with standard thread pitches of 1.0 mm to 2.0 mm depending on diameter. The screws are often coated with zinc or phosphate for additional corrosion resistance in outdoor or marine applications.
Manufacturers in construction, automotive, and machinery assembly source these screws for critical joints where vibration, temperature swings, or corrosive agents are present. They are used in structural steel connections, engine components, and outdoor infrastructure. Buyers should confirm the exact material pairing, as this determines the screw’s suitability for specific loads and environments.
| Material composition | Carbon steel core with stainless steel or hardened alloy outer layer |
| Thread type | Standard ISO metric coarse or fine pitch |
| Typical thread pitch | Standard 1.0 mm to 2.0 mm |
| Head type | Hex, countersunk, or pan head (typical) |
| Drive type | Hex socket, Phillips, or slotted (typical) |
| Corrosion resistance | Stainless steel or alloy outer layer; zinc or phosphate coating typical |
| Tensile strength | Typical 800 MPa to 1000 MPa for carbon steel core |
| Standards compliance | ISO 4017, ISO 7045 (typical) |
| Surface finish | Zinc-plated, phosphate-coated, or passivated (typical) |
| Typical applications | Construction, automotive, machinery assembly, structural steel |

Sourcing Bimetallic screw from Lianzhong Industry Co., Limited - China Import Guide
Before placing an order, verify the exact material composition and mechanical properties of the screws, as these determine their suitability for your application. Request the supplier’s mill certificates and third-party test reports for tensile strength, hardness, and corrosion resistance to ensure compliance with your project’s specifications.
Confirm logistics details such as lead time, which typically ranges from 20 to 30 days for standard orders, and Incoterms, as FOB Xinxiang or CIF to your port are common. Packaging should be checked for export readiness, with options like bulk bags, cartons, or pallets to prevent damage during transit.
Inspect a sample batch for dimensional accuracy, thread integrity, and surface finish. For critical applications, arrange a third-party inspection to verify compliance with ISO standards and the absence of defects like burrs or inconsistent coatings. Ensure all documentation, including material certificates and test reports, is provided before shipment.
