- Pan head with Phillips drive
- Thread-rolling design for the Grid System's round holes

The 1421CT25 is a pack of 25 pan head Phillips thread-rolling #12-24 screws, 0.5" long, listed as round hole hardware for the HME Grid System. It suits panel builders and OEM engineers fitting components to grid straps and door support rails inside modular freestanding enclosures, where the round holes are sized for thread-forming screws rather than cage nuts.
In the Grid System, grid straps carry a pattern of alternating square holes (for cage nuts) and round holes (for M5 or #12 screws) at standard 25 mm centers, while door support rails have round holes only. The Grid System hardware notes state that round holes accommodate the M5 and #12 thread-forming screws listed, and this #12-24 pack is one of the two round hole hardware options, alongside the M5 x 12 mm pack.
Because they are thread-rolling screws, they form their own thread in the round hole, so no cage nut or separate nut is needed on round-hole mounting points. The pan head takes a Phillips driver.
The pack has a shipping weight of 1 lbs (0.45 kg) and is REACH and RoHS compliant. Order it together with the grid straps or door support rails for your HME enclosure depth or door width to complete the mounting system.
Ideal For
- Mounting components to HME grid straps
- Fastening to door support rail round holes
- Enclosure interior mounting hardware
