Captive screws are specialized fastening components designed to remain attached to a panel or assembly even when disengaged. Commonly used in enclosures, electronics, machinery panels, and industrial equipment, captive screws improve serviceability while preventing hardware loss during maintenance.
Offshore Milling & Sourcing supports bulk and custom captive screw programs for OEM manufacturers, enclosure fabricators, electronics producers, and industrial equipment suppliers. We provide factory-direct sourcing aligned with dimensional, material, and finish requirements.
Whether your application requires standard panel captive screws or custom per-print configurations, we support scalable sourcing programs.
