Typical Applications
Suitable for panels, brackets, covers and equipment assemblies requiring a flush fixing. A4 stainless steel is useful for outdoor and coastal applications where it is appropriate to the service conditions.
Installation
Use compatible M8 x 1.25mm nuts or tapped holes. Prepare the countersink to suit the actual screw head, allowing sufficient material thickness to support it. Confirm head dimensions before machining a critical recess.
Install with a correctly fitting 5mm Allen key and a torque appropriate to the joint. Suitable lubrication and controlled installation speed can help reduce galling when assembling stainless steel threads.
