Price: 299.00

As a remodeler we find ourselves bringing existing structures up to today’s building code.  That means using larger headers and joists and using metal connectors to make safer and stronger buildings. Years back we would install these metal connectors by hand, but today we have the Senco JoistPro 250 Metal Connector.

Senco JoistPro 250

We recently got a chance to use and review the Senco JoistPro 250 metal connector nailer. The JoistPro 250 fires a single strip of 1-1/2″ to 2-1/2″ paper tape collated nails ranging from .131 to .162 in diameter.

Notable Features

The Senco JoistPro 250 is able to install nails 1 1/2″ – 2 ½.”The rear load magazine captures the fastener by the head so there is no need to adjust anything when switching between nail lengths.

Weighing in at nearly two pounds, the JoistPro 250 is light enough to work overhead and compact to work in rafter and joist bays. It has a 360˚ adjustable exhaust, dry-fire lockout, and a “large, and in-charge,” 180 adjustable rafter hanger, and a dedicated belt hook on the side.

We really liked the rafter hanger was great – it’s large and quickly deployable.

Nail Placement

The JoistPro 250  uses an integral nosepiece probe to locate the metal connector holes for accurate placement. We found this much easier than trying to use our old Bostitch which required you to place the nail tip in the connector hole.

When installing hangers on the ground, you can see the nose of the tool clearly. But most of the time you’re standing on a ladder, and once you put the tool into the position you won’t be able to see the nose at all; you’ll have to place the nail by feel.


We tested the Senco JoistPro 250 in Douglas fir framing, pressure-treated lumber and LVL engineered lumber using 2-1/2″ nails. It worked great – no issues and perfect penetration.


The Senco JoistPro 250 sells online at $299.

Overall Impression

Modern wood structures are packed with joist hangers, framing clips, and strap-ties. Today we install more metal connectors than ever the Senco JoistPro 250 eliminates a tedious, thumb-smashing procedure when installing metal connectors.
