PA–304
Air Hydraulic Riveter
Fast Riveting Starts
With A Better Grip.
Old 2-jaw tools let rivets tilt, slip and jam – and the line shuts down. M7’s 3-jaw tools grip every rivet evenly from three sides. No tilt. No slip. No jams.

The Difference
The 3-Jaw
Grip
Three hardened steel jaws wrap each rivet at equal angles, automatically centering it – so it never tilts or slips, even on a fast line.
Old 2-Jaw
Tilt. Slip. Jam.
Rivets sit off-centre, the line stalls, and operators fight every pull.
M7 3-Jaw
No tilt. No jams.
Even grip from three sides auto-centres every rivet – fast, consistent, repeatable.
The Grip Doesn’t Lie
3 Jaws Beat 2, Every Pull
Capacity by Material
What It Actually Sets
Most rivals print their biggest rivet size for soft aluminium only. M7 pulls harder – 1,000 to 1,300 kgf – so it reaches bigger sizes in tougher materials. No soft-aluminium-only surprises.

Common Questions
What is the PA-304 riveter used for?
It sets blind rivets on assembly lines and repair work, covering small-to-medium rivets from 2.4-4.8 mm.
Who is this tool best suited for?
Auto and custom shops, metal fabricators, and industrial manufacturers running fast, high-volume riveting work.
How is the 3-jaw grip different from a standard 2-jaw riveter?
Three hardened jaws wrap the rivet at equal angles and auto-centre it, so it never tilts or slips. 2-jaw tools let rivets sit off-centre, which stalls the line and jams operators.
What rivet sizes and materials does it handle?
The PA-304 covers 2.4-4.8 mm rivets in aluminum, steel and stainless – see the capacity matrix above for exact combinations.
Is the PA-304 suitable for high-volume assembly lines?
Yes. It’s tested over 40,000 pull cycles at just 1.41 kg, and the 3-jaw grip prevents the tilting and jamming that slows down fast-paced lines.
How does it compare to other 2-jaw riveters?
Most rivals are still 2-jaw and let rivets tilt off-centre. Only one competitor matches the 3-jaw grip, at roughly a much higher price.
