Combination cam lock

When sourcing combination cam locks, prioritize the housing material, typically Zinc Alloy with chrome or powder coating for corrosion resistance. Ensure the cylinder length matches your cabinet door thickness (common sizes range from 16mm to 30mm). For security, look for locks offering at least 1,000 to 10,000 possible combinations (3-digit or 4-digit wheels). Additionally, verify if the lock features a master key override function, which is critical for management access in case of forgotten codes.

For the US market, look for compliance with ANSI/BHMA Grade standards to ensure mechanical durability. For European markets, CE marking and RoHS certification (ensuring the absence of hazardous substances in metal plating) are essential. If the locks are intended for outdoor use or humid environments, request Salt Spray Test reports (e.g., 48-hour or 72-hour ASTM B117) to guarantee rust prevention.

Request information on the internal clutch mechanism; high-quality locks use a hardened steel cam to prevent forced rotation. Ask the supplier for the cycle test rating, where premium locks should withstand at least 50,000 to 100,000 opening cycles. To prevent 'code-hunting' or picking, ensure the dials have a clear tactile click and no visible gaps that allow shimming.

Combination cam locks are ideal for keyless environments such as gym lockers, office pedestals, medical cabinets, and toolboxes. Installation usually requires a standard 19mm (3/4") double-D hole to prevent the lock body from spinning. Ensure the supplier provides a complete accessory kit, including the offset or straight cam lever, hex nut, and spur washer.

The primary risk is material substitution, where a supplier might use lower-grade recycled zinc alloy that is brittle. To mitigate this, use Made-in-China.com's Secured Trading services and request a pre-shipment inspection (PSI) to verify weight and material density. Another risk is dimensional inaccuracy; always request a technical drawing (CAD/PDF) and a pre-production sample to ensure the cam throw fits your specific cabinet design.

Standard MOQs for custom finishes or branded logos usually start at 500-1,000 pieces. You can negotiate a tiered pricing structure where the unit price drops by 10-15% for orders exceeding 5,000 units. For long-term partnerships, negotiate for free spare parts (1-2% over-shipment) to cover potential mechanical failures during installation.

Metal locks are heavy, so Sea Freight (LCL or FCL) is the most cost-effective method for bulk orders. Ensure the supplier provides the correct HS Code (typically 8301.30 for cabinet locks) to avoid customs delays or incorrect duty applications. For urgent samples, Air Express (DHL/FedEx) is preferred, but ensure the packaging is reinforced to prevent the heavy metal items from breaking through the cartons.

Always prioritize Audited Suppliers on Made-in-China.com, as these manufacturers have undergone on-site verification of their facilities and business licenses. Use Escrow-based payment terms to ensure funds are only released once the shipping documents are verified. Avoid direct wire transfers to private accounts; always pay to the verified corporate account listed on the platform.
