Metallics JPMP20TF-1M – Frequently Asked Questions
1) What does Type-F mean on a 10-32 x 3/8 machine screw?
Type-F is a thread-cutting point. The screw has blunt, tapered flutes at the tip that cut their own 10-32 thread as it drives, so it goes into an unthreaded or partly damaged hole in sheet metal or a casting without a separate tap. That's the difference from a plain machine screw, which needs a hole that is already tapped 10-32.
2) Can I use these to repair a stripped 10-32 hole in a steel box or enclosure?
That is the main reason to buy a Type-F. Because the point cuts thread as it drives, the JPMP20TF-1M will often take hold in a 10-32 hole that a standard machine screw has chewed out, provided the hole hasn't opened up past #10 diameter. If the hole is oversized, step up to a larger fastener or use a thread insert instead.
3) How many screws come in a jar of the Metallics JPMP20TF-1M?
1,000 screws, packed in a jar rather than a box, so it's a shop or van quantity for crews doing repeat enclosure and cover work. Order code is JPMP20TF-1M.
4) Is this screw steel or stainless, and should I use it outdoors?
These are steel machine screws (MS St in the Metallics call-out), not stainless. Keep them to dry interior work such as panel covers, device mounting, and enclosure hardware. For wet locations or exterior enclosures, specify a stainless 10-32 instead.
5) Is 3/8 inch long enough for mounting a cover or device onto sheet metal?
For single-thickness sheet metal and standard cover flanges, yes, 3/8 inch gives enough engagement past the material while leaving nothing to foul the inside of the box. If you are stacking a gasket, spacer, or a second plate, go to a longer 10-32 so you keep thread engagement behind the panel.
6) Do I need a pilot hole for these Type-F screws?
Yes. Type-F cuts thread, it does not punch material, so the hole has to be drilled to the correct pilot size for 10-32 first. Drive with a #2 Phillips bit and avoid overdriving, since the cut thread in thin steel strips more easily than a tapped thread.
7) Why a pan head instead of a flat head for enclosure screws?
The pan head on the JPMP20TF-1M seats flat on the surface and doesn't need a countersunk hole, which is what you want on sheet-metal covers and device plates. A flat head is the choice only where the hole is already countersunk and the fastener has to finish flush.
