2-1/2" Powder Actuated Fasteners,.300 Head Diameter Drive Pin with red Flute, P250, 100pcs/pack

Securing my 2x4 studs to a cement slab was successful…

Excellent product! A+++

These nails do a perfect job of attaching the metal braces I made (and used) to secure the legs of my work bench to the concrete it sits on. The amount supplied in the box is a very good supply. They worked perfectly every time in the popular ramset I used to do the job. All VeryGood

Expected washers like pic but none. Used any and worked just didn't have washer to stop

Exactly as described at a very fair price.

Look and feel they same or better than Ramset brand. Penetrate concrete well, and if they don’t sink all the way, give them another shot.

Just what I needed to attach treated 2x4's to a concrete floor; framing out a room.

These and the gun we’re great time savers
