Metallics JSHC38212SS316 – Frequently Asked Questions
1) Is this screw 316 stainless, and can I use it outdoors or near salt water?
The material is 316 stainless steel, the marine grade. 316 adds molybdenum over 304, which is why it's specified for coastal, wash-down, chemical and roof-top work where 304 or plated steel pits. For exterior electrical gear, strut and enclosure mounting in salt air, this is the grade to ask for.
2) How many screws come in a jar of Metallics JSHC38212SS316?
100 screws per jar, and the jar is the pack format rather than a bag or box, so it reseals on the truck or the shop shelf. One jar covers a full run of 3/8-16 anchoring or enclosure work without repeat trips to the counter.
3) Do I need a nut and washer with these 3/8-16 socket head cap screws, or are they included?
The jar contains the screws only, 100 of them. Any 3/8-16 nuts, flat washers, lock washers or spring nuts for strut are ordered separately. If the assembly is going into a corrosive or exterior location, match the hardware in 316 as well, mixing in plated steel nuts gives you a galvanic weak point and defeats the reason for buying 316 screws.
4) Will a 2-1/2 inch long 3/8-16 cap screw work in a tapped hole, or does it have to go all the way through?
Either. A socket head cap screw has a machined hex socket and a cylindrical head and runs into a tapped 3/8-16 hole or through a drilled hole with a nut on the back. At 2-1/2 inches of length you have enough reach for stacked channel, a backing plate, or a thick bracket; for a blind tapped hole just confirm your thread depth, since excess length will bottom before the head seats.
5) Why pick a socket head cap screw over a hex bolt for electrical mounting work?
The internal hex drive is the reason. A socket head seats in tight quarters where a wrench cannot swing, and the small cylindrical head clears nearby conduit, gear and panel sides that a hex head would foul. It also counterbores flush when you need the head below the surface. Where you have open access and want a wrench on it, a 3/8-16 hex bolt is the simpler buy.
6) What is the Metallics part number for the 3/8-16 x 2-1/2 inch 316 stainless socket head cap screw?
Order it as Metallics JSHC38212SS316. That number breaks down the way the rest of the Metallics fastener line does: JSHC for the jar-packed socket head cap screw, 38 for 3/8 diameter, 212 for the 2-1/2 inch length, SS316 for the 316 stainless material.
