Metallics JRMN99 – Frequently Asked Questions
1) Are the Metallics JRMN99 screws plastic or metal?
Nylon, not metal. That matters on the job for two reasons: nylon is non-conductive, which is why it gets specified around energized parts and insulating barriers, and it will not corrode the way a plated steel screw does in damp locations. The trade-off is strength, so do not use it where a load-bearing or high-torque fastener is called for.
2) Can I use a nylon 1/4-20 screw instead of steel in an electrical enclosure?
If the reason for the nylon is insulation or corrosion resistance, yes, the JRMN99 threads into the same 1/4-20 hole a steel screw does. If the screw is part of a bonding or grounding path, no. Nylon does not conduct, so it cannot carry a ground connection and must not be swapped in for a bonding screw. Use a metal fastener there.
3) What head and driver does the JRMN99 screw use?
Round head with a slotted drive, so it takes a flat-blade screwdriver. Round head means the fastener sits proud of the surface rather than flush, so it is not a substitute where a countersunk hole calls for a flat head.
4) How many nylon screws come in a jar of Metallics JRMN99?
100 screws per jar. The jar pack is the shop or service-van format, which is how maintenance and electrical crews buy these: one container on the shelf covers repeated cover-plate and panel work without opening a new bag each time.
5) What is the Metallics part number to order for 1/4-20 x 1/2 nylon round head slotted screws?
Order Metallics JRMN99. That number covers the 1/4-20 x 1/2 inch nylon round head slotted machine screw in the 100-count jar.
