M8 x 12mm Captive Socket Cap Head Screw (Similar to DIN 912) | A4 Stainless Steel | Vital Parts – HSC912CT-M8-12-A4
Fasten with accuracy using this M8 x 12mm Captive Socket Cap Head Screw, a stainless steel fixing based on the recognised DIN 912 socket cap head screw style. Designed for assemblies where the screw needs to remain with the panel or component, this part combines a 8mm threaded length with a 6.2mm captive diameter, helping support repeat access and controlled installation. The 13mm head diameter, 8mm head height, H6 drive and 1.25mm pitch make it suited to compact assemblies, shallow housings and closely spaced fixing points.
Manufactured from A4 Stainless Steel with a self-colour finish, this captive cap head screw is selected for secure fastening in engineering, manufacturing and equipment maintenance environments. A4 stainless steel provides improved corrosion resistance compared with A2, making this option suitable for harsher external, washdown or marine-adjacent environments where a stainless finish is required. The socket cap head allows installation with a hex key or socket driver, giving a positive drive interface in applications where space around the head may be limited.
What Are Captive Socket Cap Head Screws?
Captive Socket Cap Head Screws are specialist fasteners used where a screw must stay attached to a panel, cover or access point after loosening. Unlike a standard fully removable cap screw, the captive design uses a reduced section and defined captive diameter so the fixing can be retained once installed with a compatible panel, washer, sleeve or retaining feature. This helps improve safety, speeds up servicing and reduces the risk of loose fasteners falling into machinery or being lost during maintenance.
Applications and Key Industries
This M8 captive socket cap head screw is used across UK manufacturing, engineering and equipment assembly where DIN 912 style head geometry, stainless steel material and a retained fixing format are required. Common use cases include:
- Machinery and Equipment: The M8 thread size and 12mm length make this screw useful for compact equipment covers, access plates and precision panel assemblies.
- Captive Panel Fixings: The 6.2mm captive diameter helps the fixing remain retained in prepared assemblies, reducing dropped or misplaced fasteners during maintenance.
- Stainless Steel Assemblies: The A4 stainless construction supports outdoor equipment, marine-adjacent hardware and exposed industrial assemblies where a neat socket cap head finish is needed.
Typical purchasers include procurement teams, design engineers, maintenance technicians, panel builders and production managers who need reliable stainless steel captive screws for repeat-access assemblies and controlled fixing points.
Why Choose This M8 x 12mm Captive Socket Cap Head Screw?
This screw is a practical choice when a standard socket cap screw could be removed and misplaced during servicing. The 8mm threaded section gives a defined engagement area while the 6.2mm captive diameter supports retention in the assembly. Because the part is Similar to DIN 912, it follows the familiar DIN 912 cap head style while providing the retained functionality required for access panels, machinery covers and specialist equipment.
Key Features
- DIN 912 style cap head: Familiar socket cap geometry with a H6 drive for secure tightening and controlled installation.
- Captive fixing design: The 6.2mm captive diameter and 8mm threaded length help keep the screw associated with the panel or component during removal.
- Corrosion-resistant a4 stainless steel construction: Suitable for stainless steel assemblies where strength, clean appearance and corrosion resistance are important.
- Application-specific length: The 12mm overall length is suited to where a shorter fixing length helps reduce protrusion while maintaining a positive socket drive.
