M3 x 40mm Captive Socket Countersunk Screw (~ISO 10642) | A2 Stainless Steel | Vital Parts - HCS10642CT-M3-40-A2
Our M3 x 40mm Captive Socket Countersunk Screw (~ISO 10642) is manufactured from A2 Stainless Steel, providing a dependable fastening solution for applications where a flush fitted head and retained screw function are required. Based off ISO 10642, these captive socket countersunk screws are suited to engineering, panel assemblies, machinery, electronics, and enclosure applications where a neat surface finish and controlled repeat access are important.
What Are Captive Socket Countersunk Screws?
Captive socket countersunk screws are specialist machine screws designed with a countersunk head and a captive section that helps keep the fastener retained with the panel or assembly. This makes them ideal for access covers, machine guards, and service panels where loose screws are not desirable. The countersunk head enables a flush finish after installation, while the machine thread allows use with threaded holes, inserts, nuts, and tapped components.
Common Applications
- Panel Assemblies: Ideal for access covers, service panels, and retained fastener applications.
- Machinery & Equipment: Suitable for guards, housings, brackets, and flush mounted components.
- Electrical & Electronics: Used in enclosures, cabinets, and compact assemblies where retained screws are preferred.
- Maintenance & Repair: Reliable for repeat access applications in industrial and commercial environments.
