• On-Time Delivery Rate: Aim for suppliers with ≥98%. Several top performers, including Zhongshan Sunbow Hardware and Haining Lianyi Lock Industry, consistently achieve 100% punctuality.
• Response Time: Rapid communication (<4 hours) indicates organizational efficiency. Qingdao Astro Hardware and Henan Locks Trading respond within one hour, facilitating faster decision-making.
• Reorder Rate: A high reorder rate reflects customer satisfaction. Qingdao Everise Int'l Co., Ltd. boasts a 36% repeat order rate, suggesting strong after-sales support and product consistency.

Quality Validation Through Sampling

Before scaling orders, conduct rigorous sample testing focused on:

• Material Hardness: Optimal picks should range between HRC 45–55 using high-carbon or stainless steel (e.g., 301 or 420 grade).
• Tensile Strength: Minimum 1,000 MPa ensures resistance to bending under torque.
• Dimensional Accuracy: Precision-ground tips must meet ±0.05mm tolerance to fit modern lock mechanisms.
• Surface Finish: Electropolishing or black oxide coating improves corrosion resistance and tactile feedback.

Always confirm that sample materials and processes match full-production specifications. Request mill test reports when available.
