  • Stronger holding power: The holding power of this numax nail is very strong. It has 16 gauge finish nails and 18 gauge brad nails which will allow the nose of the nailer to go deeper and tighter spaces. That’s how it will strengthen the holding power of the nailer.Due to this feature, numax nailer is suitable for nailing baseboards, shoe, furniture trim, crown moldings, window casings and chair rail where you actually need heavy holding power.
  • Ease to attach on drywall: Generally, when you are installing baseboards, furniture trim, crown moldings, window casings, and chair rail, you have to attach it directly to drywall. Drywalls are not made of sound materials to anchor to the base. Using Numax finish nailer will allow you to install your heavy objects on drywall directly even if the drywall is not strong enough.

  • Clear the jams without tools: There is no jam while using this Numax nailer. If the nailer gets stuck on the way, you can’t proceed. But using Numax finish nailer will relieve you from this pain as you won’t have to face any jam during nailing.
  • Two in one: NuMax SXL31,16 Gauge Finish Nailer has both 16 gauge finish nails and 18 gauge brad nails. It allows you the opportunity to switch from 16 gauge finish nails to 18 gauge brad nails or 18 gauge brad nails and 16 gauge finish nails. You can use anyone when you need.

Cons with the Solution

  • It leaves a much larger than normal striking mark in the wood: The mark is larger than normal marks on the wood. The way it works is, the 16 gauge nails load on one side of the magazine, the 18 gauges on the other, and the striking hammer is the wide enough to hit whichever nail is in its path. It makes total sense from a mechanical standpoint, but it leaves a crater in the wood that is twice the width of a normal 16 gauge nail, and about 3 or 4 times the area of an 18 gauge nail.
  • Solution: It is because the head is designed to work with brads, finishing nails and staples. It doesn’t have to. Test the type of fastener you’re using on the kind of materials you’re working with, and dial the depth control until there’s no mark. Be sure you’re using the same materials. I.e. for trim work use a scrap of the trim and a piece of wood like whatever you’re attaching the trim to as backing for best results. For paint grade trim projects, this is no problem, as the crater will get filled with caulk and painted and disappear, and that's the same amount of work regardless of the size of the crater. For stain-grade (i.e. oiled or varnished unpainted wood), the larger crater is pretty uncool. Clients for high-end jobs who are paying primo for fancy knot-free woods won't be satisfied. One way to mitigate this is to back off the depth setting so the nail is just above grade and then sink them all at the end of the project with a nail set. If the problem is not solved yet, you have to contact the manufacturer to solve this issue.
