Metallics JFMP127 – Frequently Asked Questions
1) Is the Metallics JFMP127 machine screw sold individually or by the box?
The JFMP127 ships as a jar of 100 screws, and 100 is the order minimum. So you are buying a jar, not a loose piece. The packed jar weighs 2.01 lbs.
2) What thread does a 10-24 x 3 in. flat head machine screw take, and will it run into a standard 10-24 tapped hole?
It is a #10 screw with 24 threads per inch, UNC (coarse) thread cut to ANSI/ASME B1.1. That is the standard 10-24 machine screw thread, so it will run into any 10-24 tapped hole or 10-24 nut, including device boxes and fixture straps tapped 10-24.
3) Does the Metallics JFMP127 screw meet Buy American requirements for a government job?
No. The JFMP127 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. If your project carries a domestic sourcing clause, this is the wrong line item.
4) What size Phillips bit drives these Metallics flat head screws?
A #2 Phillips. The recess measures 0.198 in. diameter, 0.124 in. deep, with a 0.032 in. slot width, which is standard #2 geometry. Use a sharp #2 bit; a #1 will cam out and a #3 will not seat.
5) Is a zinc plated steel machine screw okay for outdoor or damp locations?
These are steel with a zinc finish, which is a plating for dry indoor service. For wet locations, exterior mounting, or anywhere washdown or salt is a factor, specify a stainless 10-24 machine screw instead. The zinc yellow finish is common in electronics and panel work.
6) How much load will a 10-24 steel zinc machine screw hold?
Rated at 1,050 lb minimum tensile, with the steel running Rockwell B70 to B100 hardness from AISI 1006-1022 stock. That is a general-purpose low carbon machine screw, not a structural or graded bolt, so size it for fixture and device mounting rather than for structural loads.
7) Is the 3 inch length measured including the head?
Length is 3 in. Flat head screws are measured overall, head included, under ASME B18.6.3-1998, so the usable grip below the surface of a countersunk hole is the full 3 in. less the head height of 0.098 to 0.116 in.
8) What are 10-24 x 3 in. flat head machine screws typically used for?
Long 10-24 flat heads like this are stocked for electrical, plumbing, and HVAC work: pulling device plates and fixture straps through thick build-ups, reaching into deep boxes or through furring and plaster rings, and general panel and equipment mounting where the head has to finish flush.
