A BSW countersunk head shoulder cap screw is a specialized imperial fastener that combines a flush-fitting head with an unthreaded shoulder. This hybrid design is primarily a custom or non-standard item, as standard BSW fasteners typically feature either a countersunk head (for flush finish) or a shoulder (for pivoting) but not both in a standard configuration.
