Our take on the FLEX 24V Brushless 21 Degree Framing Nailer Kit

The FLEX FX4351A is a cordless 21-degree framing nailer built on FLEX's 24V battery platform. It fires up to 3 nails per second with no ramp-up and drives up to 1,100 nails per charge on a 5.0Ah pack, so it competes with gas and pneumatic framers without hoses or fuel cells. A depth dial, bump and sequential modes, a nail indicator, dry-fire lockout, dual LEDs and a pivoting rafter hook cover the day-to-day framing needs. It suits remodelers, deck and shed builders, and crews already on FLEX 24V; buyers tied to another battery platform will pay more for the bare tool and charger.

What reviewers say

Owner feedback on the FX4351A is limited but consistent: it drives framing nails reliably, the depth dial and bump mode speed up production, and runtime on a 5.0Ah pack holds up on deck and wall framing. Complaints center on weight with the battery mounted and on the cost of staying in the FLEX battery system.

What people mention
  • RuntimePraisedOwners say a 5.0Ah pack lasts through a long framing session.
  • WeightCriticisedSeveral note the gun feels heavy and nose-heavy with the battery in place.
  • Depth controlPraisedThe depth dial is easy to set and holds through a run of nails.
  • Firing modesPraisedSwitching between bump and sequential fire is quick and the selector stays put.
  • Nail angleMixedThe 21-degree magazine limits buyers to plastic-collation nails.
  • Battery costCriticisedBuyers outside the FLEX 24V platform find the extra batteries and charger a real expense.

About the FLEX 24V Brushless 21 Degree Framing Nailer Kit

The FLEX 24V Brushless 21° Framing Nailer is a cordless framing nailer that works without hoses or compressors. It drives up to 3 nails per second with zero ramp up time. With a 5.0Ah lithium-ion battery, it drives up to 1,100 nails on a single charge. It accepts 2-inch to 3-1/2-inch fasteners and has a metal magazine.

A dial adjusts the driving depth, and a depth indicator is included. Dual LED lights illuminate dark work areas. The tool switches between bump and sequential firing modes. A nail indicator shows how many nails remain in the magazine, and a dry-fire lockout prevents blank firing when the nails run out.

The heavy-duty belt clip mounts on either side of the tool and has a lead-in profile. A pivoting rafter hook holds the tool for storage when not in use. It has a soft grip and a non-mar nose tip. It works with all FLEX 24V batteries, chargers, and tools.

Questions and answers

The listed kit contents are the nailer, rafter hook, belt clip, three no-mar tips and an Allen key. Confirm the battery and charger are in the box before buying if you need them.
What nails does it take?
It accepts 2-inch to 3-1/2-inch fasteners in a 21-degree plastic-collation magazine. It does not take 30-degree paper-tape nails.
How many nails per charge?

Can it fire bump and sequential?
