Metallics JRMN71 – Frequently Asked Questions
1) Is the JRMN71 screw metal or plastic?
Nylon, not metal. It is a nylon round head slotted machine screw, so it is non-conductive and won't corrode, but it carries far less clamp load and torque than a steel or stainless screw of the same 5/16-18 size. For structural or load-bearing fastening, use a metal machine screw instead.
2) Why would an electrician use a nylon screw instead of a steel one?
Because nylon does not conduct. The JRMN71 is a 5/16-18 x 1-1/4 nylon machine screw stocked as an electrical fastener, which is where you want an insulating, non-corroding fastener, for example mounting or isolating a part where a steel screw would create a path to ground. It gives up strength for that, so it is not a substitute where the joint carries load.
3) What driver do I need for the Metallics JRMN71 machine screw?
A flat blade screwdriver. The JRMN71 has a slotted round head, so no Phillips, square, or hex driver applies. Drive it by hand or at low torque, since nylon heads strip and the slot deforms more easily than steel.
4) Does the JRMN71 nylon screw come with a nut?
No. The JRMN71 is sold as screws only, 50 to a jar. If you are fastening through a non-tapped hole you will need to order matching 5/16-18 nuts and any washers separately.
