Fastener FAQ
Q: What factors should I consider when selecting fasteners for outdoor applications?
A: For outdoor fastener applications, prioritize corrosion resistance by choosing materials like 316 stainless steel or hot-dip galvanized fasteners. Consider environmental factors such as saltwater exposure, temperature fluctuations, and UV radiation. The fastener's coating or plating should match the severity of the environment it will face.
Q: How do I determine the correct fastener size for my project?
A: Fastener sizing requires three key measurements: diameter (major diameter for bolts/screws), thread pitch (distance between threads), and length (measured from under the head to the tip). For critical applications, consult engineering specifications or our technical team. Always ensure threaded fasteners engage at least 1.5 times the diameter in the mating part.
Q: What's the difference between machine screws and bolts?
A: Fastener classification depends on application. Machine screws typically have finer threads and are designed to be used with pre-tapped holes or nuts in precise machinery. Bolts generally have coarser threads and are used with nuts to clamp materials together. The distinction often comes down to the mating component and the required precision of the joint.
Fastener Installation Best Practices
- Clean all mating surfaces before installation
- Use the proper tools to avoid damaging fastener heads
- Apply appropriate torque using calibrated torque wrenches
- Use thread locker for vibration-prone applications
- Inspect fasteners periodically in critical applications

Additional Fastener FAQ
Q: What certifications do your fasteners carry?
A: Our fastener products meet multiple international standards including ISO 898-1 for mechanical properties, ASTM specifications for material composition, and RoHS compliance for restricted substances. Many of our aerospace fasteners are also NADCAP accredited for special processes.
Q: How should I store fasteners to maintain quality?
A: Fastener storage best practices include keeping products in original packaging until use, maintaining dry conditions (40-60% humidity), and separating different materials to prevent galvanic corrosion. For critical applications, consider climate-controlled storage for sensitive coatings or materials.
Q: What's your lead time for custom fastener orders?
A: Standard custom fastener production typically requires 4-6 weeks from design approval to shipment. Expedited services are available for urgent projects. Lead times vary based on material availability, complexity of design, and finishing requirements. Our sales team provides precise timelines after reviewing specifications.
