Metallics SN256 – Frequently Asked Questions
1) What thread size does the Metallics SN256 hex nut take?
The SN256 is a 2-56 nut, so it threads onto a #2 machine screw with 56 threads per inch. It will not run on a #4 or #3 screw, and a #2-64 fine screw will not thread into it either. Match the screw callout exactly before ordering.
2) Is the Metallics SN256 nut stainless, and will it hold up outdoors or in a damp location?
It's 18-8 stainless steel, the common austenitic grade used where plated steel would rust. That makes it suitable for damp interior work, outdoor enclosures and general corrosion exposure. For chloride-heavy coastal or pool environments, a 316 fastener is the better call.
3) How many nuts come in a pack of Metallics SN256?
Each pack is 100 pieces of the 2-56 finished hex nut. For panel builders and electricians running small machine screws in volume, that is the unit you buy, not an individual nut.
4) What part number do I order for the Metallics 2-56 stainless hex nut?
Order Metallics SN256. That is the manufacturer part number for the 2-56 finished hex nut in 18-8 stainless, supplied 100 to a pack.
5) What is the difference between a finished hex nut and a machine screw nut in this size?
A finished hex nut like the SN256 has a thicker body and a washer-bearing face, so it carries more clamp load and seats more evenly than a thin machine screw nut of the same 2-56 thread. If a drawing calls for a machine screw nut because of tight clearance behind a panel, the finished nut may sit too proud.
6) Is the Metallics SN256 magnetic, and does that matter for electrical work?
18-8 stainless is essentially non-magnetic in the annealed condition, though cold forming can leave it slightly magnetic. It is also non-sparking relative to plated carbon steel and resists galvanic issues against other stainless hardware in an enclosure. Pair it with stainless screws rather than zinc-plated ones to avoid mixed-metal corrosion.
