Metallics JNYN1601SS – Frequently Asked Questions
1) What thread size are the Metallics JNYN1601SS lock nuts, and will they fit a standard 8-32 machine screw?
The JNYN1601SS is an 8-32 hex nylon insert locknut, 32 threads per inch cut to ANSI/ASME B1.1 unified inch threads. It runs onto any standard #8-32 machine screw or bolt, which is the common size for device screws, enclosure covers, strut fittings and panel hardware.
2) Are these stainless locknuts suitable for outdoor or wet, corrosive locations?
They are made of 316 stainless steel, the marine grade with molybdenum added, so they hold up in wet exterior, coastal and chemically aggressive environments far better than zinc-plated or 18-8 hardware. Mechanical properties follow ASTM F594, the standard for stainless steel nuts.
3) Can I use the Metallics JNYN1601SS on a federally funded Buy American job?
No. These nuts are flagged as not Buy American compliant and not ARRA compliant, with country of origin listed as multiple. If your project specification carries a domestic sourcing requirement, you need a documented domestic-origin fastener instead.
4) What wrench or socket size do I need for these 8-32 nylon insert locknuts?
Across the hex flats the nut measures 0.336 to 0.345 inch, so an 11/32 inch socket or wrench is the fit. Height across the body is listed at 0.219 to 0.239 inch, with a 0.14 inch dimension also given, useful if you are checking clearance behind a cover plate or inside a shallow box.
5) Do nylon insert locknuts need a lock washer, and can they be reused?
No separate lock washer is needed. The nylon collar in the top of the nut deforms around the screw threads and grips them, which is what resists vibration loosening, so the JNYN1601SS does the job of a plain nut plus a washer. The insert loses bite each time it is run off a screw, so plan on fresh nuts for anything that has to stay put. There is also no metal-to-metal locking feature, which keeps the mating threads from galling, a real benefit with stainless on stainless.
6) How many 8-32 stainless locknuts come in a jar and what is the minimum order?
They ship in a jar of 100 pieces, and 100 count is the order minimum. The jar packaging is practical for a truck or a shop bin, and other sizes and quantities in the Metallics JNYN series can be arranged on request.
7) Are these locknuts dimensionally standard so they interchange with other brands of 8-32 nylon insert nuts?
Yes. The JNYN1601SS is built to ASME B18.16.6, the dimensional standard for prevailing-torque lock nuts, so the hex and thread geometry matches any other 8-32 nylon insert locknut made to that spec. Swapping brands on an existing assembly will not change your socket size or clearance.
8) Is there a temperature limit I should know about with nylon insert locknuts in electrical gear?
The locking element is nylon, so it is a mechanical polymer collar rather than a metal deformation lock. Keep that in mind near heat-producing equipment: where service temperatures are high, an all-metal prevailing torque nut is the better choice. For ordinary enclosure, strut, raceway and device mounting work the nylon insert style is what is normally specified.
