Butterfly Latches - Heavy Duty Case Hardware

Q: What is the minimum order quantity (MOQ)?

We have no minimum order for in-stock catalog items - order even 1 piece if you need it. Shipping is freight collect for sample and small quantity orders. For custom laser engraving, private labeling, or non-catalog specifications, MOQ varies by product model and manufacturing process. Contact our sales team with your specific requirements for a precise quote and lead time.

Q: What materials are available for industrial hardware products?

We manufacture in 5 primary materials, each specified for different operating environments: SUS304 stainless steel - excellent corrosion resistance with passivated finishes available for enhanced durability in harsh environments (consult our engineers for specifications). Our most popular choice for marine hardware, food processing equipment, and outdoor enclosures. SUS201 stainless steel - cost-effective option for indoor dry environments with good general corrosion resistance. Cold-rolled carbon steel (SPCC) - high tensile strength for heavy-load applications, available with zinc, nickel, or chrome plating for corrosion protection. Zinc alloy (ZAMAK) - precision die-cast for complex geometries, naturally corrosion-resistant, ideal for decorative and medium-duty applications. ABS plastic - lightweight, non-conductive, and chemical-resistant, perfect for electronic equipment cases and medical instrument enclosures. Not sure which material fits your project? Send us your application specs - temperature, humidity, load requirements - and our engineers will recommend the best option within 24-48 business hours.

Q: What is the typical lead time for production and delivery?

In-stock items : Ship within 48 hours of order confirmation. Standard catalog models (made-to-order) : 7-15 business days. OEM / custom tooled products : 25-35 business days depending on part complexity and tooling requirements. Express / urgent orders : Rush production is available for an additional fee - contact your account manager for options. Shipping time varies by destination: typically 3-7 business days via air express (DHL/FedEx/UPS), and 15-30 days by sea freight. We also support factory pickup for customers with their own forwarders. You'll receive a tracking number within 24 hours of shipment.

Q: Can I request custom OEM / ODM manufacturing?

Absolutely - OEM and ODM manufacturing is a core part of our business. We support: Custom sizes & shapes : Full tooling design based on your drawings, samples, or concept sketches. Surface finish options : Polished, brushed, powder coated, chrome plated, nickel plated, zinc plated, and custom colors. Logo marking : Laser engraving, silk screening, embossing, or custom mold inserts. Packaging customization : Branded boxes, foam inserts, custom labels, and export-grade packaging. Material modification : Custom alloys, food-grade 316 stainless steel, and RoHS-compliant materials.

Simply send us your drawings or samples for a free quote within 2 business days.

Q: What quality certifications and testing do your products have?

Our factory is ISO 9001:2015 certified and operates under GJB (Chinese Military Standard) quality management systems for defense-grade products. Every batch undergoes rigorous testing before shipment: Surface finish testing - coating thickness measurement, adhesion cross-cut test, and roughness inspection ensure consistent finish quality across every batch. Load & tensile testing - verified working load and ultimate tensile strength for every latch, hinge, and handle model. Cycle durability testing - 10,000+ open/close cycles for moving components. Dimension inspection - 100% caliper and gauge inspection for critical dimensions. RoHS compliance - all materials meet EU RoHS 2.0 standards for restricted substances. We provide material certificates (MTC) and inspection reports upon request for every order. For large-volume or mission-critical applications, third-party inspection by SGS or Bureau Veritas is available at cost.

Q: What are butterfly latches used for?

Butterfly latches (also called case latches or chest latches) are surface-mounted latches with a distinctive wing-shaped design that pivots to lock. They're a classic hardware choice for: Wooden and aluminum cases - briefcases, attache cases, instrument cases, sample cases Display and exhibit cases - decorative yet functional appearance Storage chests and boxes - medium-duty securing of lids and doors Point-of-sale displays - customer-accessible merchandise cases They are typically lighter duty than industrial toggle latches and are designed for medium-duty applications with occasional to moderate use. Most models include a small padlock hole for basic security.
