Metallics JNYN170SS – Frequently Asked Questions
1) What wrench size do I need for the Metallics JNYN170SS 12-24 nylon insert locknut?
Across the flats the nut measures 0.430 to 0.439 inch, and the width is the wrench size, so a 7/16 inch wrench or socket fits it. Nut height runs 0.298 to 0.328 inch.
2) Will the JNYN170SS thread onto a 12-24 machine screw in a panel or enclosure?
Yes. It's a 12-24 nut, 24 threads per inch, cut to ANSI/ASME B1.1, so it mates with any standard 12-24 machine screw or stud, which is the common thread for enclosure and panel hardware.
3) Is this stainless locknut suitable for outdoor or damp electrical work?
The nut is 18-8 stainless steel, so it holds up in wet and outdoor locations better than plated carbon steel. For chloride or coastal exposure, 316 stainless is the step up.
4) Should I use a nylon insert locknut or a split lock washer with a plain nut?
A nylon insert locknut like the JNYN170SS resists loosening from vibration using the nylon collar instead of a washer, and it needs no second part on the stack. Downside: the nylon limits service temperature and the locking collar loses grip after repeated removal and reinstallation. For high heat or frequent disassembly, use an all metal locknut or a plain nut with a lock washer.
5) How many 12-24 locknuts come in a jar, and can I buy fewer?
They ship as a jar of 100, and 100 count is the order minimum, so a jar is the smallest buy.
6) Does the Metallics JNYN170SS meet Buy American and ARRA requirements for a public project?
The JNYN170SS is flagged compliant for both Buy American and ARRA, which is what a government, school, or municipal spec usually asks for on fasteners.
7) What dimensional standard does this hex nylon insert locknut follow?
Dimensions follow ASME B18.16.6, the standard for prevailing torque nuts, with threads to ANSI/ASME B1.1. If your drawing calls out B18.16.6 for the nylon insert nut, this meets it.
8) How hard is this stainless locknut, and will it gall on a stainless screw?
Hardness runs Rockwell B95 to C35. Like all 18-8 on 18-8 pairings, it can gall if run down fast and dry, so drive it slowly or use an anti-seize on long engagements.
9) How much does a jar of 100 of these 12-24 stainless locknuts weigh?
A jar of 100 comes in at 0.93 lbs, with the jar measuring 3 in by 3 in by 2.15 in.
