Metallics JSNM5SS – Frequently Asked Questions
1) What wrench or socket size do I need for the Metallics JSNM5SS M5 hex nut?
The across-flats dimension is the wrench size on these nuts, and Metallics lists the head width at 7.78 to 8. So an 8 mm wrench or socket drives the JSNM5SS M5 nut. Nut height runs 3.7 to 4.
2) Will a Metallics M5 stainless hex nut hold up outdoors or in a damp mechanical room?
Yes. The JSNM5SS is 18-8 stainless to Class A2-70, which is made for corrosive service. Pair it with screws and bolts of similar stainless material, mixing stainless nuts onto plain or zinc-plated bolts in a wet location sets up galvanic corrosion at the joint.
3) Is the M5 thread on this nut metric only, or will it fit a #10 screw?
Metric only. The JSNM5SS is an M5 hex nut with a 0.8 mm standard metric pitch, and it will not thread onto a #10-24 or #10-32 machine screw. For imperial screws you need a #10 nut, not this one.
4) How many M5 nuts come in a jar, and can I buy a smaller quantity?
These ship 100 to a jar, and 100 count is the order minimum. Metallics does offer other sizes and quantities by request, but the standard pack here is the 100-piece jar.
5) Do these Metallics stainless nuts meet Buy American and ARRA requirements for a public project?
Metallics lists the JSNM5SS as compliant for both ARRA and Buy American purposes. Country of origin is recorded as multiple, so if your spec requires a single named origin on the certification, confirm the origin for the lot you receive.
6) What is the Class A2-70 marking on a stainless nut telling me?
A2 is the stainless grade (the 18-8 austenitic family) and 70 is the strength class, so A2-70 nuts are matched to A2-70 stainless bolts and screws. It is a corrosion-resistance spec first, not a high-strength substitute for an alloy steel Grade 8 or Class 10.9 nut. If the drawing calls for a hardened structural nut, this is not the part.
7) How much does a jar of 100 M5 stainless nuts weigh for shipping or a van stock list?
A jar comes in at 0.27 lbs, with jar dimensions of 3 by 3 by 2.15 inches. Small enough to keep several sizes on the truck without eating shelf space.
8) Is the Metallics JSNM5SS a plain hex nut or a hex flange nut?
Metallics catalogues it as a metric hexagonal nut in the JSNM series, and notes the flange design spans oversized or poorly aligned holes and gives a more uniform bearing-stress to clamp-force ratio. If your assembly needs a free-spinning washer face against sheet metal or a strut channel, that flange is what does the work; otherwise add a separate stainless flat washer.
