Metallics JFMP90SS – Frequently Asked Questions
1) Will an 8-32 machine screw thread into my existing device or box tapped holes?
The Metallics JFMP90SS is an 8-32 UNC machine screw cut to the ANSI/ASME B1.1 thread standard, 32 threads per inch. Any 8-32 tapped hole, device yoke, or box ear will take it. It is a machine thread, not a self-tapping screw, so the hole has to already be tapped.
2) What size Phillips bit drives the Metallics JFMP90SS screws?
A #2 Phillips. The recess is 0.182 in. across, 0.11 in. deep, with a 0.03 in. slot width. Stainless cams out more readily than plated steel, so keep the #2 bit seated and the driver straight rather than running it at high speed.
3) Are these stainless screws OK for outdoor, wash-down, or refrigeration work?
18-8 stainless is specified for general atmospheric corrosion resistance, and Metallics calls out food processing machinery and refrigeration equipment as typical uses. It also holds strength better than plain steel at elevated operating temperatures. For damp mechanical rooms, exterior boxes, and kitchen equipment it is the right material choice over zinc-plated steel.
4) Is 2-1/2 inches too long for mounting a device in a standard box?
At 2-1/2 in. under the head, these are a long-reach 8-32. They are meant for deep mud rings, thick plaster rings, stacked spacers, or running through an extension to reach the tapped ear. For a flush device in a standard 1-1/2 in. deep box, a 2-1/2 in. screw will bottom out or leave thread hanging inside the box, so step down to a shorter 8-32.
5) Do these Metallics machine screws meet Buy American or ARRA requirements for a public project?
Metallics lists the JFMP90SS as both ARRA compliant and Buy American compliant. Country of origin is recorded as multiple, which is normal for this family, so if your specification requires a single named origin on the submittal, confirm the origin on the lot you receive.
6) How are the Metallics JFMP90SS screws packaged and what is the minimum I can buy?
They ship in a jar of 100, which is also the order minimum, one count unit. The packed jar weighs 1.17 lbs. Useful quantity for a service van where you are pulling a few long 8-32s at a time rather than a bulk box.
