Metallics JNYN160 – Frequently Asked Questions
1) Will the Metallics JNYN160 locknut fit an 8-32 machine screw?
Yes. The JNYN160 is an 8-32 hex nylon insert locknut, cut 32 threads per inch to ANSI/ASME B1.1, so it threads onto any standard 8-32 machine screw or bolt. Nothing else needs to match, since the nylon ring does the locking rather than the thread form.
2) Do I still need a lock washer with a nylon insert locknut?
No. The nylon insert in the JNYN160 grips the screw threads and resists back-off on its own, which eliminates the need for a lockwasher under the nut. That also means you are not stacking an extra washer thickness onto a short screw.
3) Are these locknuts suitable for equipment that vibrates, like rooftop HVAC units?
That is the main use for them. Metallics lists the JNYN nylon insert locknut for areas of high vibration and for the electrical, plumbing, heating and air conditioning trades. Typical jobs are strut and channel assemblies, panel and enclosure hardware, blower and fan mounts, and anything where a plain hex nut would walk loose.
4) Are Metallics JNYN160 locknuts Buy American or ARRA compliant for a federal job?
No. The JNYN160 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. On a federally funded project with domestic sourcing requirements, you need a domestically produced locknut instead.
5) What wrench or socket size do I need for these 8-32 nylon insert locknuts?
The hex measures 0.336 to 0.345 inch across the flats, which is an 11/32 inch wrench or socket. Overall nut height runs 0.219 to 0.239 inch, so allow roughly a quarter inch of screw projection past the mating part before the nylon even starts to engage.
6) Can zinc plated steel locknuts be used outdoors or in a damp mechanical room?
The JNYN160 is steel with a zinc finish, which handles indoor and sheltered use and damp mechanical spaces. Zinc plating is a sacrificial coating, not stainless, so for direct weather exposure, coastal air, or wet wells you want a stainless or hot dip galvanized nut instead.
7) How many 8-32 locknuts come in a jar, and can I buy fewer than 100?
They ship as a jar of 100, and the jar is the minimum order unit, so 100 pieces is the smallest quantity. The packed jar weighs 0.44 lbs. Metallics does make other sizes and quantities available by request if 100 of this size is not what you need.
8) Do these nylon insert locknuts meet a recognized dimensional standard for spec work?
Yes. The JNYN series is built to ASME B18.16.6, the dimensional standard for prevailing torque nylon insert lock nuts, with threads to ANSI/ASME B1.1. If a submittal calls out a B18.16.6 nylon insert nut in 8-32, this answers it.
9) Can I reuse a nylon insert locknut after taking the assembly apart?
Treat them as limited reuse. The nylon ring in the JNYN160 deforms around the screw threads to create the locking action, and it loses grip each time it is cycled. For a joint in a high vibration location, which is what this nut is intended for, fit a fresh nut on reassembly. That is part of why they come 100 to a jar.
