Metallics JFMP107SS – Frequently Asked Questions

1) What thread does the Metallics JFMP107SS machine screw have, and will it take a standard 1/4-20 nut?
It's a 1/4-20 UNC thread, 20 threads per inch, made to ANSI/ASME B1.1. Any standard coarse 1/4-20 nut or tapped 1/4-20 hole will take it. Length is 2-1/2 inches.
2) What size Phillips driver do I need for these 1/4-20 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 engages properly. Using a #2 on these will cam out and chew the recess.
3) Are these stainless machine screws OK outdoors or in a damp mechanical room?
18-8 stainless is specified for general atmospheric corrosion resistance, so outdoor, damp, and washdown locations are its normal use. It also holds strength better than plain steel as application temperature rises. Food processing machinery and refrigeration equipment are common applications. For direct salt spray or chemical immersion, 18-8 is not the grade to reach for.
4) How strong is a 1/4-20 18-8 stainless machine screw in tension?
1,900 lb minimum tensile, with hardness in the Rockwell B85 to B95 range. Worth knowing: there is no national performance standard for stainless machine screws, so those figures are guides rather than a graded rating. If your drawing calls out a graded fastener such as a Grade 5 or Grade 8 bolt, a stainless machine screw is not a substitute.
5) How are the Metallics JFMP107SS screws packaged, and what is the minimum order?
They come 100 to a jar, and 100 count is the order minimum. So the smallest buy is one jar of 100.
6) Do these Metallics stainless screws meet Buy American and ARRA requirements on a federal job?
The JFMP107SS is flagged compliant for both Buy American and ARRA. Country of origin is China. On a federally funded project, give your compliance officer both facts, since some specifications accept the compliance flag and some require domestic melt and manufacture.
7) Is a machine screw the right choice, or do I need a self-tapping screw?
A machine screw has a straight, uniform machine thread and no point, so it needs an existing tapped hole or a nut. It will not cut its own thread into sheet metal, wood, or masonry. For an electrical enclosure, device box, strut, or equipment chassis with factory 1/4-20 threads, this is the correct fastener. If you are starting from an untapped hole, tap it first or use a thread-cutting screw.
8) Is 2-1/2 inches of screw length all thread, and how much grip do I actually get?
Length is measured from the top of the flat head to the point of the screw, because flat heads are countersunk and sit below the surface. So on a 2-1/2 inch flat head, the full 2-1/2 inches is your usable grip plus nut engagement, not 2-1/2 inches on top of the head height. Plan your stack thickness accordingly and leave at least a thread or two past the nut.
9) What does the Metallics JFMP107SS jar of 100 weigh for shipping or stocking a van?
The jar runs 2.89 lbs, in a package measuring 3.5 x 3.5 x 5.75 inches. Light enough to keep several sizes on the truck without a weight problem.
