We are currently looking to procure a substantial quantity of headless set screws for one of our clients with projects in Africa. Specifically, we require 8000 pieces that meet certain specifications. The screws should be manufactured from high-grade steel, featuring a black oxide finish if possible. The required dimensions include a hex socket drive with a specific key size, as well as precise thread sizing and pitch parameters. Additionally, please ensure that the screws are right-handed and have a cup point design. We would appreciate it if you could provide us with your pricing, lead times, and any relevant certifications on these products. Your prompt response will be highly valued.
