A General Overview

The NuMax SFL618 is a lightweight hardwood flooring nailer built with a body made of aluminum. It has an ergonomic grip handle for easy maneuverability along with interchangeable base plates, which allows you to move from 1/2 inch to 3/4 inch plates according to hardwood floor thickness. Which one is really great for any floor nailer.

When using this NuMax floor nailer, owing to its extended handle, you will never face any achy back. You don’t have to hit hard, too, because its light strike bumper gives you low impact fastener driving. To push hardwood floors in place, it comes with a white rubber mallet.

Therefore it is an ideal tool for efficient handling of professional jobs and home DIY projects.

Features Of Numax SFL618 

Multi-Functional: 3-in-1

You can need to drive many flooring nails and even staples depending on your working condition when you start fastening floor planks. L-shaped or T-shaped cleats are ideal for the installation of thicker-shaped hardwood floors with high Janka hardness species including Red and White Oak, Tigerwood, Cumaru, or Amendoim. On the other side, staples are a good option for building subfloors made of plywood.

So, grab the NuMax SFL618 pneumatic 3-in-1. It will allow you to drive both L-shaped and T-shaped cleats and 15-1/2 to 16 gauge staples without damaging your hardwood floor or leaving any marks on it.


You cannot use a flooring nailer to do other nailing work like framing or siding. On top of that, if you buy a floor nailer that can only do a single job, your investment would not be worth it. Instead, if you have a hardwood flooring nailer that can fasten different kinds and thicknesses of floorboards, it is always better.

With NuMax 3 in 1 flooring nailer, nails can be driven into a wide variety of different thickness floorboards starting from Oak to Maple or Hickory. What you have to do is change their interchangeable base plates. It comes with two base plates for 1/2 inch and 3/4 inch thick flooring.

Not only does it help you to drive cleats or staples tightly, but it also helps protect your finish flooring surfaces thanks to its no-mar feature. This is also the right choice for DIYers to achieve skilled results undertaking home renovation and maintenance tasks as well as construction workers on the job site.

Construction And Materials

If you’re talking about its construction, the NuMax floor nailer is of heavy-duty quality. This nailer is not only flexible but also strong and sturdy.

In order to ensure reliability and toughness, a body made of die-cast aluminum and heat-treated steel has been built of different sections of this flooring nailer. Since it requires constant movement, it is prudent for the manufacturer to use aluminum as a body material, which makes it not only durable but also lightweight.

So, yes. You don’t need much muscle strength to push the machine on the floorboards, just as it won’t harm the finished floors.

Durability, Longevity, And Power

Numax is a brand that offers a wide range of products, including framing nailers, finish nailers and more that are highly acceptable to both professional contractors and DIYers. They follow a stringent quality management protocol and use the most robust materials during the manufacture of their equipment. The NuMax flooring nailer SFL618 is no exception to this. You will, therefore, be assured of its durability and longevity.

When it comes to power, it can drive 1-1/2 inch to 2 inches, 15.5 to 16 gauge cleats, and crown staples smoothly at a power of 70 to 110 psi.

Comfort And Maneuverability 

If you want to install 3/4-inch hardwood planks on a 300-square-meter wooden subfloor with 2-inch L-cleats, you need about 8 hours of work as a professional contractor. If you need to cover a bigger floor area or you’re a DIYer, you’re going to need more time to finish. So, the nailer you’re going to use to do this job should be ergonomically comfortable.

And if you touch the NuMax SFL618, you can feel the ergonomics of it. It comes with a rubber-lined handle for easy grip and is ergonomically designed to ensure ease of operation during long shifts. Its lightweight body construction, weighing 12 pounds only, gives you incredible balancing power, too.

Real Value For The Money

Like every other NuMax nailer, this device is premium but less costly than its rivals. And you’re getting a flooring nailer for hardwood installation that is balanced, robust, reliable, and highly comfortable at a cheaper but high-end tool size.

Cons Of Numax Flooring Nailer With Solution

No dry-fire lockout system

When you get used to this app, you will no longer need a dry-fire locking system. Until then, you can either inspect the strike zone frequently or watch the exhaust sound (it become louder at the end of the magazine) to protect the dry fire.

You may adopt Brandon’s strategy as well. Mr. Brandon is a Numax floor nailer user and engineer at BSME, Northeastern, USA. He put some blue painter’s tape on the magazine where the pusher rests. It stops the pusher when there are only 5 to 10 nails left.

No case for storage

It will be better if it comes with a storage case, at least for the extras (oil, augments, etc.). Whatever, to store it properly for the sake of reuse, you can buy a bag or a tool organizer for the accessories. You can try this Heavy Duty Rolling Chest & Cabinet Storage Box by Stalwart.

Frequently Asked Question (FAQ)

Q. Which will be the better option for a hardwood flooring nailer, buy or rent?

It depends on the size and nature of the project you’re going to handle. If you are a DIYer and need to install hardwood floors for a single room, it might seem cheaper to rent a floor nailer than buy one. However, if you compare the price of the tool, especially the Numax floor nailer, you may find that the cost of rent for three or more days is equal to the price of a new device. If you’re a professional manufacturer, buying a hardwood flooring nailer will be the best way then rent.

Q. Is the Numax SFL618 compatible with every nail brand on the market?

Of course! You could use any generic brand, like Bostitch floor nails or staples, to drive with the Numax flooring nailer.

Q. Can I use finish or brad nails in this gun?

Oops! You cannot. It only allows the fasteners are 16 gauge “T & L” cleats and 15.5 gauge staples. However, in a limited case, you can use a brad nailer or a finish nailer to fasten hardwood floors.

Q. Should I use staples or nails for hardwood flooring?

There are two kinds of hardwood floors – solid and engineered. Generally, nails that are also known as cleats in solid wood floors and staples for plywood or engineered boards should be used. However, both staples and cleats could be used for both floor types. Due to the need for a vapor barrier, it is important to use only the recommended length of the nails and staples so that they can only reach the subfloor.

Q. What should be the correct size of nails for 3/4 inch hardwood flooring?

When building 3/4 “solid wood flooring over a subfloor with floor joists, or when building 3/4” flooring over a concrete slab, over two 1/2 “plywood layers, you could use 2-inch long cleats.
