The AU-VE-CO PRODUCTS 12253 is a black push nut designed for M5 screw sizes with a 15mm outside diameter. Push nuts, also called speed nuts or push-on fasteners, secure components onto non-threaded shafts or smooth studs without the need for tools - they press on and grip by spring tension. This fastener is used across HVAC, automotive, appliance, and light manufacturing applications wherever a quick, tool-free retention method is needed. At 0.01 pounds, it is a lightweight hardware item typically purchased in quantity for production or service use. Installation requires no threading and no adhesive, making it a practical choice for high-volume assembly or field repair work.
This push nut is suited for residential and light commercial applications where M5 shafts or posts require a secure retention clip. Common use cases include fan blade retention, panel fastening, and component mounting in HVAC equipment, appliances, and similar assemblies. The black finish blends with most equipment interiors. With a minimum order quantity of 100 units, this part is intended for shop stock or bulk service inventory rather than single-unit repair.
Designed for use with non-threaded fasteners and M5 shaft or stud applications in HVAC, appliance, and general mechanical assemblies.
Push nuts are installed by pressing the fastener firmly onto the shaft or stud by hand or with a flat tool until it seats flush. No threading is required. Ensure the shaft diameter matches M5 specifications before installation, as push nuts are not reusable once fully seated. This hardware is typically handled by HVAC technicians, appliance repair technicians, or mechanical assemblers as part of a broader component replacement procedure.
