I'm looking to source high-precision spindle screws with lengths ranging from 2 to 8 meters. These screws are critical for our production lines, so it's essential that they meet strict quality standards for precision and durability. Could you provide details on your available options, including specifications, pricing, lead times, and any relevant certifications? Also, please let me know about your capabilities for bulk orders and whether you have custom solutions available.
