Metallics JFSC3834 – Frequently Asked Questions
1) What thread size and length is the Metallics JFSC3834 socket head cap screw?
It's a 3/8-16 x 3/4 inch screw, so 3/8 inch diameter with 16 threads per inch (standard UNC coarse thread for that diameter) and 3/4 inch of length. It mates with any 3/8-16 tapped hole or nut.
2) Is the JFSC3834 a flat head or a standard socket cap head?
Flat head. The JFSC3834 is a flat head socket cap screw (SHCS FH), so it sits flush in a countersunk hole and is driven with a hex key, not a screwdriver. If you need the screw head to sit proud on the surface, a standard cylindrical-head socket cap screw is the one to order instead.
3) What material and finish is the Metallics JFSC3834 screw?
Steel with a black finish (St-Blk). That's a plain, non-plated black oxide type finish, which is fine for dry interior work but offers little corrosion protection, so for damp or exterior locations choose a plated or stainless fastener instead.
4) How many screws come in a jar of Metallics JFSC3834?
100 pieces per jar. Metallics ships this one in jar pack, which is the typical shop or service-truck bulk put-up for small fasteners, so order in multiples of 100 if you're stocking a van or a maintenance crib.
5) Will a 3/4 inch long flat head socket screw be long enough for my application?
With a 3/4 inch overall length and a flat head, the head length is consumed by the countersink, so the usable grip is close to the full 3/4 inch below the surface. That suits thin plate, bracket, and strut-type fastening into a tapped 3/8-16 hole or a nut. Deeper assemblies need a longer 3/8-16 screw.
6) What is the Metallics part number for the 3/8-16 x 3/4 black flat head socket cap screw?
JFSC3834 is the Metallics catalog and manufacturer part number for the 3/8-16 x 3/4 black steel flat head socket cap screw in the 100-piece jar.
7) Can I use the JFSC3834 screw for electrical enclosure and support work?
Yes, it's carried as an electrical fastener and the flush flat head is useful where a protruding head would interfere with a cover, gasket, or panel face. It needs a tapped 3/8-16 hole or a mating nut, and a countersink to seat properly.
