Metallics JMTLN8SS – Frequently Asked Questions
1) What thread size is the Metallics JMTLN8SS kep lock nut, and will it fit a standard metric bolt?
It is an M8 nut, so it threads onto standard M8 metric bolts, studs, and threaded rod. It will not fit imperial 5/16 inch or 3/8 inch hardware, those need an inch-series nut instead.
2) Is the JMTLN8SS nut stainless steel, and can it be used outdoors or in damp locations?
The nut is 18-8 stainless steel, the common 300-series austenitic grade used where corrosion resistance matters. That makes it suitable for exterior, damp, and wash-down work where a plain or zinc-plated nut would rust. Pair it with stainless bolts or rod to avoid galvanic issues between dissimilar metals.
3) What is a kep nut and do I still need a separate washer?
A kep nut (also called a K-lock or star washer nut) is a hex nut with a free-spinning external-tooth lock washer captured under the flange. The washer is part of the nut, so you do not add a separate lock washer, the teeth bite into the mounting surface as you tighten and resist loosening from vibration. It is a one-piece assembly, which is why electricians favor it for panel, strut, and enclosure work.
4) How does the Metallics M8 kep nut ship, loose or in a container?
It ships as a jar of 100 pieces, which is the pack type for this item. That is a shop or van quantity, convenient for a service truck bin rather than a bulk box for a production run.
5) Will a stainless kep nut hold a ground connection on an enclosure?
The toothed washer on a kep nut cuts through paint or coating as it tightens, which is why these are commonly used to land bonding and grounding hardware on painted enclosures and strut. The 18-8 stainless body keeps the connection from corroding in wet or exterior locations. Follow whatever bonding method your inspector accepts for the specific equipment.
6) Can a kep nut be reused after I take it apart?
A kep nut relies on its toothed washer digging into the clamped surface, so once the teeth have set they are flattened and the locking action is reduced. For a joint that has to hold against vibration, replace with a fresh nut on reassembly. Having 100 in the jar makes that practical.
7) What part number do I order for the Metallics M8 stainless kep nut?
Order Metallics JMTLN8SS. That single part number covers the M8 hex kep lock nut in 18-8 stainless, supplied in a jar of 100, and there are no size or finish choices to specify with it.
