Quality & Inspection Process

Material Testing

  1. Mechanical property validation, including tensile strength, yield strength, shear resistance, and torque requirements for customized bolts, screws, studs, pins, and locking elements.
  2. Metallurgical composition inspection (ASTM / ISO standards) for carbon steel, alloy steel, stainless steel, brass, titanium, and other specialty materials used for high-performance fastening.
  3. Heat-treatment certification checks, verifying hardness, core hardness, case depth, and durability for quenched, tempered, or carburized fasteners.
  4. Surface coating assessment, ensuring plating, anodizing, galvanizing, black oxide, or anti-corrosion coatings meet required salt-spray resistance and environmental specifications (RoHS/REACH).

Machining Process Control

  1. Precision thread machining control, maintaining thread accuracy (internal & external) according to custom specifications — UNF, UNC, metric, trapezoidal, or specialized thread forms.
  2. Strict tolerance management for diameter, concentricity, pitch, head shape, and recess geometry, ensuring perfect fit and fastening performance in complex assemblies.
  3. Cold heading, CNC machining, stamping, and turning process optimization for producing non-standard geometries, asymmetric heads, miniature sizes, or high-strength fasteners.
  4. In-process torque & locking performance testing, ensuring stability for self-tapping, self-locking, anti-loosening, or vibration-resistant designs.
  5. Surface finishing control, guaranteeing uniform coating thickness, adhesion stability, wear resistance, and consistent appearance across large production batches.

Final Inspection

  1. Dimensional and thread accuracy inspection using gauges, CMM, optical measurement systems, and Go/No-Go thread gauges to ensure all custom features meet specifications.
  2. Torque, preload, and tightening force validation, ensuring fasteners meet mechanical requirements when installed in end products.
  3. Hardness and core integrity testing, preventing cracks, brittleness, or deformation in high-stress applications.
  4. Surface integrity inspection to detect burrs, sharp edges, coating defects, dents, discoloration, and thread damage—especially important for precision-assembly industries.
  5. Functional assembly simulation, ensuring fasteners fit perfectly with counterpart components in real installation scenarios.

Pre-Shipment Verification

  1. Lot-by-lot traceability confirmation, including material certificates, heat-treatment records, plating batch numbers, and manufacturing history.
  2. Random sampling torque and fastening performance re-validation to ensure consistency across the entire batch before shipment.
  3. Protective packaging inspection, guaranteeing anti-rust coating, moisture protection, and customized partitioning to avoid collision and thread damage during transport.
  4. Final compliance audit, verifying the fasteners meet customer drawings, industry standards, and special requirements (high-strength, anti-loosening, anti-corrosion, miniature size, specialty geometry, etc.).
