Push-ons in the PV and PZ styles have more push-off force, allowing these shaft retainers to be easier to slide on and remove than the PS style. Also known as Shaft Retainers, PV and PZ style Push-ons are self-threading and self-locking fasteners with inner teeth that slide over a non-threaded stud to secure two panels together. They greatly reduce installation costs and problems associated with cross-threading. Push-ons have prevailing torques that provide excellent resistance to vibration, and can simplify your designs. Available in standard and metric designs with 6 inner teeth plus a variety of materials and finishes, these PV and PZ style Push-ons can accommodate larger studs and reduce insertion efforts.
