Custom Non-Standard Metal Screw Manufacturing Solutions
For industries requiring precision-engineered fasteners, our OEM factory specializes in producing custom non-standard metal screws tailored to your exact specifications. We work with high-performance materials like stainless steel, titanium, and alloy steels, delivering durable, corrosion-resistant solutions for demanding applications.
Materials Expertise:
Stainless Steel (304/316): Ideal for marine, chemical, and food-grade environments.
Titanium (Grade 2/5): Lightweight, ultra-strong, and biocompatible for aerospace, medical, and automotive use.
Alloy Steels (Grade 8.8/10.9): Heat-treated for high tensile strength and fatigue resistance.
Specialized Screw Types:
Self-Tapping Screws: Eliminate the need for pre-drilled holes in metals, plastics, or composites.
Hex Head/Hex Socket Drives: Compatible with high-torque tools for secure fastening.
Custom Threads/Heads: Non-standard lengths, diameters, thread pitches, or head designs (e.g., flanged, countersunk).
Customization Capabilities:
Prototyping: Rapid CNC-machined samples for testing and validation.
Surface Treatments: Zinc plating, Dacromet®, anodizing, or passivation for enhanced durability.
Thread-Locking Patches: Nylon or adhesive coatings for vibration resistance.
Aerospace: Titanium screws for lightweight structural assemblies.
Automotive: Self-tapping hex screws for engine components and panels.
Medical: Biocompatible titanium fasteners for surgical tools and implants.
Renewable Energy: Stainless steel screws for solar/wind installations.
Industrial Machinery: High-strength alloy screws for heavy equipment.
