Frequently Asked Questions About Spring Pin Latches
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.
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.
- 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.
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.
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.
Spring pin latches (also called spring-loaded bolt latches or pin locks) use a spring-loaded pin that automatically engages when the door closes, securing it with a simple push. To release, you pull back a knob or handle against spring tension.
Features and applications:
Features and applications:
- Automatic locking - latches automatically when the door closes, no manual latching required
- Simple and reliable - very few moving parts, minimal failure points
- Common uses - cabinet doors, access panels, equipment enclosures, trailer doors, and utility doors
- Locking options - many models include a padlock hole or key lock for added security
Yes, but you need to select the right material and finish:
- SUS304 stainless steel - the best choice for outdoor and marine environments. Excellent corrosion resistance and maintains smooth spring operation in harsh conditions.
- Zinc-plated steel - suitable for sheltered outdoor or indoor/outdoor transition areas. Lower cost but less corrosion resistance.
- Powder coated - available in various colors, provides an extra layer of corrosion protection.
