Metallics MN4F Nails 4D Bright Finish Steel (Jar 1350)

The MN4F is a 4d bright finish nail in steel, with a flat head, sold 1350 to a jar. Metallics lists it for interior and exterior wood finish work, so trim, casing, stop, shoe mold and similar light finish carpentry. 4d is the penny size designation; it is a short nail suited to thin trim stock rather than framing.

Metallics lists the MN4F for interior and exterior wood finishes. Keep in mind bright means plain, uncoated steel with no protective plating, so on fully weather exposed work most finish carpenters go to a galvanized or stainless nail to avoid rust bleed through paint. For covered exterior trim or anything that gets painted and sealed, the bright nail is the normal choice.

No. The MN4F is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project has domestic sourcing requirements written into the spec, this nail will not satisfy them and you need a domestically produced fastener instead.

One jar holds 1350 of the 4d bright finish nails and weighs 2.61 lbs. The jar is the pack type, and the minimum you can order is 1 each, so a single jar is a valid order for a small punch list.

Metallics offers other sizes and quantities of these bright finish nails on request, so if 4d is too short for your trim or you need more than the 1350 count jar, a different size or pack can be sourced. The MN4F part number itself covers the 4d bright steel nail in the jar.

MN4F nails ship loose in a jar of 1350, so they are hand driven with a hammer and nail set. They are not collated strips or coils and will not load into a pneumatic finish nailer.

The MN4F uses a flat head. Metallics classifies it as a finish nail for wood finish work, so it is intended to be driven and filled on trim. If you need a truly headless look for delicate molding, a brad or pin is the better call.
