Metallics JFSC638 – Frequently Asked Questions
1) What head and drive does the JFSC638 screw use, and what tool do I need?
It is a flat head socket cap screw, so the drive is an internal hex socket and you drive it with an Allen key or hex bit, not a screwdriver. The flat head is meant to sit flush in a countersunk hole.
2) What is the JFSC638 screw made of and what is the finish?
Steel with a black finish. That is a plain black steel fastener, not stainless and not galvanized, so keep it to dry indoor work; outdoor or damp locations call for a stainless or coated screw instead.
3) How many screws come in a jar of Metallics JFSC638?
100 screws per jar. Metallics packs these in a jar rather than a box, which is what you want on a service van or a shop bench where you are pulling a few at a time.
4) Is the JFSC638 a self-tapping or sheet metal screw?
No. It is a machine screw with a 6-32 machine thread, so it needs a pre-tapped hole or a nut. For driving directly into sheet metal without tapping, you need a self-drilling or sheet metal screw, not this one.
5) What part number do I order for the Metallics 6-32 x 3/8 black steel flat head socket screw?
Order Metallics part number JFSC638. That single MPN covers the 6-32 x 3/8 flat head socket cap screw in black steel, supplied 100 to a jar.
