Procurement & Technical FAQ

Answers to common queries from engineering and purchasing departments.

What quality control certifications does TIGHTU hold?
Our manufacturing facility is fully CE Certified. We adhere strictly to ISO 9001 quality management systems. Every batch of screws, bolts, nuts, and washers undergoes rigorous tensile strength, torque, and salt-spray testing before dispatch.
Can you manufacture fasteners to specific international standards?
Absolutely. We routinely manufacture components complying with DIN, ISO, and ANSI/ASME standards. If your project requires adherence to JIS or specialized automotive/aerospace standards, please contact our engineering team.
What is the typical lead time for OEM/ODM custom orders?
For standard catalog items, we maintain significant inventory for rapid dispatch. For custom OEM/ODM projects, prototyping typically takes 7-14 days. Mass production lead times range from 3 to 5 weeks depending on the complexity of tooling, material availability, and required surface treatments.
