Metallics JFSC516114 – Frequently Asked Questions
1) What thread size and length is the Metallics JFSC516114 socket flat head cap screw?
It's a 5/16-18 x 1-1/4 inch socket flat head cap screw. The 18 threads per inch is the UNC coarse pitch for 5/16 diameter, so it mates with standard 5/16-18 coarse nuts and tapped holes, not a fine-thread 5/16-24 hole.
2) Will a socket flat head cap screw sit flush with the surface?
Yes, if the hole is countersunk for it. A socket flat head seats in a countersink and finishes flush with the material face, which is why it gets used where a protruding hex or socket cap head would foul a mating part, a panel, or a strut face. Drill or counterbore the 5/16 hole with a matching countersink before installing. Drive is an internal hex (Allen) socket in the head, so you need a hex key or bit, not a screwdriver.
3) How many screws come in a jar of Metallics JFSC516114?
One hundred screws, packed in a jar rather than a loose box, so the count holds up in a van or on a shelf without spilling. The jar is the sell unit, so order by jar quantity.
4) Is the JFSC516114 screw plain steel or coated, and can I use it outdoors?
These are steel with a black finish, which is a dry, indoor-duty finish. Black oxide style coatings give little corrosion protection on their own, so for wet locations, exterior runs, or damp mechanical rooms specify a stainless or zinc plated cap screw instead of the black steel version.
5) What is the Metallics part number I should order for a 5/16-18 x 1-1/4 black socket flat head screw?
JFSC516114 is the Metallics part number for the 5/16-18 x 1-1/4 inch steel black socket flat head cap screw in the 100 count jar. That one number covers the whole pack.
