Nuts 12-24 Cage Nut St-BP (Jar 50)
Additional Notes
- Other sizes and quantities available by request – some sizes available in stainless steel
Features
- More economical and easier to install than other heavy duty nuts for blind side applications. Free floating nut will compensate for poorly aligned holes. The saquare cage design keeps the nut from roatating during tightening. Cage nuts are sucessfully used in heavy duty farm machinery, rail cars, home entertainment components and heating equipment among other applications.
- A free floating square nut retained within a spring steel cage. The cage has two retaining legs on the same side of the nut, positioned 180 deg from each other, that hold the nut in place at panel edges or center panel locations.

Metallics CNN1224 – Frequently Asked Questions
1) What panel thickness will the Metallics CNN1224 cage nut clip onto?
The CNN1224 cage nut is built for sheet metal from 0.025 to 0.063 inch thick. The spring steel cage snaps over the panel edge or into a center-panel hole within that range. Thicker plate will spread or not retain the cage, so for heavier material you want a weld nut or a tapped hole instead.
2) What size screw does a 12-24 cage nut take?
It takes a 12-24 machine screw, that is a #12 diameter at 24 threads per inch. This is the standard thread used in rack and enclosure panels, so any 12-24 rack screw threads straight into it.
3) Will a cage nut still work if my panel holes do not line up well?
That is exactly what it is for. The square nut floats free inside the cage, so it shifts to pick up a screw coming in slightly off center. The square cage pocket also stops the nut spinning while you torque the screw, which is the usual failure with a loose nut in a blind cavity.
4) Can I use these where I cannot reach the back side of the panel?
Yes, blind side work is the point of a cage nut. You clip it on from the accessible side and it stays captive, so you never need a wrench behind the panel. Two retaining legs sit on the same side of the nut, 180 degrees apart, holding it in place.
5) Do Metallics CNN1224 cage nuts qualify for a Buy American or ARRA funded job?
No. The CNN1224 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. On a federally funded project with domestic sourcing language, you need a domestically produced fastener instead.
6) How big a hole do I need to punch for this cage nut?
The nut body measures 0.510 to 0.530 inch across in width and 0.510 to 0.531 inch in length, with a head width of 0.531 inch and a height of 0.156 inch. In practice that means a square punch on the order of a half inch plus clearance for the cage legs. Measure the part you have in hand against those figures before punching a run of panels.
7) Is the black phosphate finish on these cage nuts suitable for outdoor or damp locations?
The CNN1224 is plain steel with a phosphate coating, black in color. Phosphate gives mild corrosion resistance and a good surface for lubricant or paint, but it is an indoor or dry-location finish, not a weather finish. Stainless steel is offered in some sizes by request if you need corrosion resistance.
8) How many cage nuts come in a jar and can I buy fewer than 50?
They ship 50 to a jar, and 50 each is the order minimum, so the jar is the smallest buy. Other sizes and quantities are available by request.
9) Are these cage nuts hard enough to hold up in equipment and machinery, not just sheet metal boxes?
The cage is spring steel at Rockwell C44-51 hardness, made to SAE 1050-1065 and SAE 1018 material standards. That hardness is why the legs keep their spring after repeated screw changes. Typical use runs to farm machinery, rail cars, heating equipment and electronics chassis.
10) What trades normally stock 12-24 cage nuts on the truck?
Electrical, plumbing, and heating and air conditioning crews are the main users, typically for mounting into enclosure panels, equipment housings and duct-mounted gear where there is no access behind the sheet metal. A 50 count jar weighs 0.6 lbs, so it is easy to carry in a van bin.
