Metallics JFSC5161 – Frequently Asked Questions
1) Does the JFSC5161 socket head cap screw sit flush, or does the head stand above the surface?
It sits flush. The JFSC5161 is a flat head socket cap screw (SHCS FH), meaning a countersunk conical head driven with a hex key. The hole needs a chamfer or countersink cut for the head angle; in a plain drilled hole the head will stand proud. If you want a head that bears on the surface, use a standard button or cap head rather than the flat head version.
2) Is the black finish on these 5/16-18 socket screws suitable for outdoor or damp locations?
No. These are steel with a black finish (St-Blk), which is a plain black oxide type coating on carbon steel, not a corrosion barrier like hot dip galvanizing or stainless. Keep them to dry interior work. For wet locations, exterior runs, or anywhere washdown is involved, specify a galvanized or stainless 5/16-18 fastener instead.
3) How many screws come in a jar of Metallics JFSC5161?
100 pieces per jar. The jar pack is the standard unit for this part number, so a single order quantity gets you 100 of the 5/16-18 x 1 inch flat head socket cap screws rather than a loose count, which is what makes it practical to stock on a service truck or in an MRO crib.
4) What is the Metallics part number to reorder these black flat head socket cap screws?
Order Metallics JFSC5161. That one number covers the 5/16-18 x 1 inch flat head socket cap screw in black steel, jar of 100, and it is the only configuration that part number is built in, so there is no size or finish suffix to add.
