Allen-Bradley NSB 2-1 2 HW Set Screw Coupling

Allen-Bradley NSB 2-1 2 HW Set Screw Coupling is a set-screw shaft coupling listed as a fastener (EA). This hardware component provides a straightforward, secure connection between two shafts by engaging set screws that clamp onto the shaft surfaces, offering a simple, reliable joining method in mechanical assemblies. The NSB designation identifies the product family within Allen-Bradley’s catalog, while the HW variant indicates the hardware-focused option in that line. Sold as individual units (EA), this coupling is intended for single-piece procurement and integration into standard maintenance or replacement workflows where a conventional, non-threaded joining solution is appropriate.
