Senco FinishPro® 23LXP Micro Pinner


Manufacturer: Senco
Model number: 23LXP

Earlier this year Senco announced the new FinishPro® 23LXP. This new miro-pinner is an industrial grade headless pin nailer perfect for jobsite and factory trim work and cabinetry.  In fact, they introduced this model which uses pins from 1/2″ up to 2″ in length, and a smaller version which uses pins from 1/2″ up to 1-3/”. I’ve been testing the larger model out in the wood shop over the past few weeks and wanted to share my thoughts and some more specifics about this well built nailer.

Senco Micro Pinner

Durability and Performance

Two features stick out in my mind after spending some time testing this new pin nailer and those are Durability and Performance. The 23LXP is built from quality materials including a heavy duty cast body and a lower aluminum fastener magazine. The quality materials will perform very well in industrial and commercial settings.

Senco 23LXP Micro Pinner - 1 Inch Pins in Hard Maple

Performance is as important as anything and the 23LXP performs very well. In order to test how well the pinner works I loaded some 1-1/2″ long pins and fired a long line of pins into Maple and Purple Heart (both quite hard). As you can see above at 85 psi working pressure the pinner sunk the pins flush in both materials (the wood is pieces left from a glue-up for a cutting board).

I didn’t try 2″ long pins (I didn’t have any on hand) however, from what I experienced it’s very likely this pinner will handle 2″ pins just as well as it did the 1-1/2″ ones. Having a model available with this longer length capacity, really opens up the uses for a headless pinner. Being able to use a 2″ long pin certainly opens up many more tasks that previously may have been done with a trim gun.

To see how easy it is to place pins accurately I drew a pencil line and tried nailing along the line. I think I did a great job and that’s really due to how easy you can see the tip.

In addition to the quality build and precise operation I was pleased with several other features including: the swivel air coupler, the ease of using the double safety trigger and how easy it is to load pins into this tool. The pins simply slide into a slot in the magazine which keeps them from falling out and also gives you a good positive position to slide them into.

Overall Thoughts

Over the last year there have been several new pin nailers released into the market. On the down side the Senco 23LXP is quite a bit larger than some of the other models, however, it also allows 2″ long pins, something the others do not offer. On the up side the 23LXP is built like a tank and it offers great power and penetrated each pin I shot below the surface (something some of the other pinners can’t always say).

MSRP is set at $229, so far I haven’t seen this model advertised online so see what the difference might be. If retail pricing gets down below $200 then I think this pinner will do pretty well. If you’re in the market for an industrial strength pinner then I’d recommend you consider the Senco 23LXP Micro Pinner.

    How does the Senco FinishPro 23SXP compare to the Bosch FNS138-23? Do you have a preference?

    1. Todd Fratzel

      Brent – First let me say both of these pin nailers are quality tools that can both be used on a PRO grade level. Having said that I tend to gravitate to the Bosch ( It’s more compact which I like because it feels a bit more balanced. On the other hand, the Senco can shoot much longer pins (up to 2″) which can be a big factor for some users. Either way, they are both really good quality tools. Good luck.

    do you know if this nailer shoots both pin nails & nails w/slight heads?

      This is strictly a 23 gauge pin nailer. 23 gauge pins do not have heads.
