Metallics NYN163BO – Frequently Asked Questions
1) What thread size is the Metallics NYN163BO locknut, and what bolt does it fit?
It is a 1/4-20 nut, so it threads onto any 1/4 inch bolt, screw, or rod with standard UNC coarse thread (20 threads per inch). It will not run onto a 1/4-28 fine thread fastener.
2) What is a nylon insert locknut and when should I use one instead of a plain hex nut?
The NYN163BO is a hex nut with a nylon collar pressed into the top. As the bolt threads through, it cuts into the nylon, and the friction keeps the nut from backing off under vibration. Use it on strut, equipment mounts, fan and motor assemblies, or anywhere movement would shake a plain hex nut loose. A plain hex nut is fine for static joints or where you are using a lock washer or thread locker instead. One thing to plan for: the nylon takes a set, so these are not intended for repeated removal and reinstallation on the same nut.
3) How many nuts come in the Metallics NYN163BO pack?
1,500 pieces per box. That is a bulk electrical-trade quantity, sized for shops and MRO cribs standardizing on 1/4-20 hardware rather than for a single service call.
4) Is the Metallics 1/4-20 nylon insert locknut suitable for outdoor or wet use?
Treat it as an indoor, dry-location fastener. The NYN163BO is a black finish steel locknut, which gives light corrosion resistance and a dark appearance but is not a weather or washdown finish. For exterior, damp, or corrosive locations, specify a stainless steel or hot dip galvanized 1/4-20 nylon insert locknut instead.
5) What part number do I order for the Metallics 1/4-20 hex nylon insert locknut?
Order Metallics MPN NYN163BO. That number covers the 1/4-20 hex nylon insert locknut in the black finish, supplied 1,500 per box.
