Metallics JFMP100 – Frequently Asked Questions
1) What thread does the Metallics JFMP100 machine screw have, and will it thread into a 1/4-20 tapped hole or box?
It's a 1/4-20 UNC thread, 20 threads per inch, made to ANSI/ASME B1.1. That means it threads straight into any standard 1/4-20 tapped hole, strut nut, or channel nut. Length is 3/4 inch, so you get usable engagement through thin sheet steel and into a nut or tapped boss.
2) Do these Metallics machine screws meet Buy American or ARRA requirements for a government job?
No. The JFMP100 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On federally funded or Buy America jobs it will not satisfy the domestic sourcing requirement, so a domestically produced fastener has to be specified.
3) What size Phillips bit do I need for these 1/4-20 flat head screws?
A #3 Phillips. The recess is 0.276 inch in diameter and 0.16 inch deep, which is deeper and wider than a #2 bit will properly seat in. Running a #2 on these is how you cam out and chew the recess.
4) How many screws come in a jar of Metallics JFMP100?
They ship as a 100-count jar, and 100 is the order minimum. Jar weight is listed at 1.12 lbs. Good buy if you are stocking a van or a shop drawer rather than grabbing a handful.
5) Are zinc plated steel machine screws okay for outdoor or wet locations?
These are zinc plated carbon steel (AISI 1006-1022). Zinc plating is a dry-location and indoor-enclosure finish, fine for panels, boxes, strut and fixture work inside. For exterior, damp, or corrosive locations you want stainless machine screws in the same 1/4-20 x 3/4 size instead.
