Metallics SFLN50 – Frequently Asked Questions
1) What trade size conduit does the Metallics SFLN50 lock nut fit?
The SFLN50 is a 1/2 inch conduit lock nut, so it threads onto 1/2 inch trade size fittings and conduit, including the 1/2 inch male threads on box connectors and rigid or EMT fittings. One size only, no other trade sizes under this model number.
2) Do Metallics SFLN50 lock nuts meet Buy American or ARRA requirements for a government job?
No. The SFLN50 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your specification carries a domestic-content clause, this part will not satisfy it and you need a domestically sourced lock nut.
3) Are Metallics SFLN50 conduit lock nuts sold individually or only by the jar?
They ship as a jar of 100 pieces, and the order minimum is one jar of 100. There is no single-piece break on this item, which is why it suits a service van or a shop bin rather than a one-off repair.
4) Are these steel lock nuts zinc plated for damp or outdoor panel work?
The SFLN50 is steel with a zinc finish. Zinc plating gives basic corrosion resistance for indoor and typical dry or damp commercial installs. For direct weather exposure, wet locations, or corrosive environments, specify a fitting and nut rated for that condition instead.
5) Do I still need a bushing or bonding fitting if I use these lock nuts?
A lock nut only secures the fitting to the enclosure. It does not protect conductors or provide a listed bonding path, so an insulating or insulated-throat bushing and, where the job calls for it, a separate bonding locknut or bushing are ordered in addition to the SFLN50.
6) How much does a jar of 100 1/2 inch conduit lock nuts weigh and how much shelf space does it take?
A jar of 100 SFLN50 nuts weighs 0.92 lbs, with the container measuring 3.6 x 3 x 3 inches. Light enough to keep several sizes on the truck without eating into payload or bin space.
