Pros And Cons of Bostitch F21PL framing nailer

Advantages Of Using Bostitch F21PL Nailer

  • Well-built and powerful enough to handle the toughest job on the site.
  • The positive placement feature is great for nailing joist hangers
  • Aggressive framing tip allows easy toenailing
  • Tool-less adjustable depth features

  • The bottom loading system makes it more user-friendly

Limitations Of Bostitch F21PL

It has no dry fire lockout system

Yes, there is indeed no dry fire lockout system in this nailer. However, once you become habituated, saving your nail gun from dry-firing will not be an issue. You can measure the endpoint of nail strips easily. Moreover, the magazine is a bit slanted in design, which gives you a clear view of the nail’s area.

Switching between firing modes is a bit time-consuming

Though it takes some time to switch between sequential and bump firing modes, it is better to use single actuation if you think about safety. If you are not expert enough, then you do not need to frequently change between sequential and bump, too.

Little bulkier and heavier to work with all-day

Despite many complaints about its weight, its entire dimensions are 14.25 by 20.25 inches, and it weighs only 8.1 pounds. This indicates that it can easily travel between 16 inches O.C. and that its body bulk is insufficient when compared to its driving power and usability. As a result, it is the best-in-class framing nailer with a great power-to-weight ratio.

Advanced Features Of BOSTITCH F21PL Framing Nailer

Two-in-One Nailer 

Its two-in-one feature comes first in our mind if we compare the BOSTITCH with its other heavyweight rivals. Yes, Guys! BOSTITCH F21PL has a built-in unique interchangeable nosepiece that allows you to switch between the framing gun option to the sink joist holder nailer. This positive placement feature is a plus for those who need to handle decking works regularly.

So, you can perform the usual framing and metal connecting work with the help of this device without an issue.

Quality Build

Nail Gun is a critical tool in the sense that inappropriate handling will lead to serious incidents. Therefore, building quality is an essential feature of every framing nailer, and Bostitch correctly addresses it while producing Bostitch f21pl round head. They use magnesium as a structural material, which is a heavy-duty, but lightweight alloy used extensively in manufacturing sectors nowadays.

Affirmatively, magnesium is sturdy enough to withstand the struggles of busy work locations in your daily job and last longer. Accidentally falling from your hand one or two times would not be enough to sever the Bostitch F21PL.


Driving energy is not a big issue for framing works of small-scale projects. However, if you have to do moderate or high-profile tasks like continuously framing a 4×4 truss or decking, then clearly very often, you need to drive nails deep into the engineered lumber, which requires significant energy. If you have a Bostitch framing nailer in your hand, there is nothing to worry about this matter as it combines energy and efficiency in a proper manner.

Bostitch F21PL offers you 1050 in-pound power to drive every nail precisely without putting pressure on your compressor. You can operate this device with 80 to 120 psi pressure. So, an air compressor that can generate this much pressure is enough to run it smoothly. You can do sheathing, siding, or strapping in any thickness of wood, or even in a thin sheet easily with this tool.

Comfortable Grip and user-friendly

F21PL Bostitch nail gun is designed to guarantee maximum convenience for its user. Yep! It comes with built-in rubber skid pads that protect your hand from touching the weapon during nailing and ensure a firm grip.

Weight is a significant consideration for any framing gun as contractors sometimes spend the whole day on it. Thanks to Bostitch, they present us with a framing nailer that is not so heavy or large that it creates muscle cramps and is not so light to decay rapidly. 8.1 pounds is the ideal match between energy and mass.

Bostitch F21PL comes with a depth control push button. With this device, you can change the depth of the drive, merely by pushing a button. It enables you to nail distinct kinds and thicknesses of materials quickly and continuously without any break time.

Furthermore, the gun connects with the air compressor at the bottom instead of the rear, which means nothing comes between you and your nail gun during nailing. Thus, you can use this device freely like a cordless nailer.

21 degree Round Head Nails

Bostitch F21PL design for shooting 21-degree round head plastic collated nails that are most widely used and available in the market. Round-head nails are also engineered to provide more excellent structural stability than clipped head nails and match the building code in the maximum number of states of America.

HurriQuake Nails

If you want to build a house in a hurricane-prone area, it is highly recommended to use HurriQuake nails. However, every nailer in the market cannot drive HurriQuake nails except Bostitch.

Anti-Jam Mechanism

Getting jammed during driving nails kills significant work time. Thanks to the anti-jam mechanism of F21PL, you can clear the jam quickly within seconds. In the case of nail guns not shooting nails, you can read our blog on this too.

Adjustable Rafter Hook

Often on the job site, you need to keep your two hands-free. A Rafter hook allows you to hang your nailer with a joist to free up your hand. F21PL BOSTITCH is equipped with an adjustable rafter hook, which gives you the above facilities too.
