New Senco JoistPro Nailers

JoistPro 150MXP Nailer

The JoistPro 150MXP nailer fires 1 1/2-inch nails from .131 to .148 in diameter. The 34° extended magazine holds two strips of Senco paper-tape collated nails. With double the nails in the clip, you cut the time spent reloading in half.

Senco has also added a redesigned adjustable hook to this JoistPro Nailer. It uses heavier-gauge steel, which lets you securely hang the nailer from a tool belt or rafter.

The nose design exposes each nail tip before it fires, letting you pick your placement into the pre-punched holes of your metal connecting hardware.

At 5.3 lbs., the Senco JoistPro 150MXP nailer is more than a pound lighter than the similar Paslode PF150S-PP positive placement nailer. It’s nearly a pound heavier than the Everwin MCN40, MAX SN438J, Metabo HPT NR38AKM, Dewalt DWMC150, and Bostitch MCN150. Those models, however, lack the extended magazine.

JoistPro 250MXP

The Senco JoistPro 250MXP Nailer is the next step up for power. It fires 1 1/2-inch to 2 1/2-inch nails that can range from .131 to .162 inches in diameter. However, because this model features a rear-load magazine that captures the nail by its head, you don’t need to make manual adjustments when switching gauges.

This model also features the 34° extended magazine that holds two strips of paper-collated nails. The redesigned hook and modified nosepiece both appear on this model as well.

Additionally, the 250MXP has an upgraded depth-of-drive wheel. Not only does this improved wheel increase the tool’s overall durability, but it also allows for more consistency in various materials.

Again, Senco has cut the weight on this nailer model to 6.6 lbs. That makes it almost two pounds lighter than the Paslode F250S-PP but a little over 1/2-pound heavier than the Bostitch MCN250S. It’s almost identical in weight to the Metabo HPT NR65AK2M but without the ridiculously long head length.

Shared Features

Both of the new Senco JoistPro Nailers feature a 360° adjustable exhaust port to redirect blowback. Dryfire lockout prevents damage to the tool should you try to fire it without any nails. Both models also feature Senco’s comfort-grip overmolding.

Released alongside the new nailers, Senco also has new metal connector nails. The hardened nails come in these configurations: 3,000 .148-inch by 1 1/2-inch; 2,500 .148-inch by 2 1/2-inch; and 2,000 .162-inch by 2 1/2-inch.

Pricing

Both Senco JoistPro Nailers come with 5-year limited warranties. The 150MXP retails for $209, while the 250MXP will run you $294—a modest premium over the prior models with single-strip magazines.
