Air Hydraulic Riveter
Big Rivets Need
A Bigger 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. The PA-204 pulls 1,300 kgf, reaching up to 6.4 mm rivets in tougher materials. No soft-aluminium-only surprises.

Common Questions
What is the PA-204 riveter used for?
It sets blind rivets on heavy-duty assembly and repair work, covering rivets up to 6.4 mm — the largest range in the M7 riveter line.
Who is this tool best suited for?
Auto and custom shops, metal fabricators, and industrial manufacturers running heavy-duty, large-rivet 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-204 covers 2.4–6.4 mm rivets in aluminum, steel and stainless — see the capacity matrix above for exact combinations.
Is the PA-204 suitable for heavy-duty assembly lines?
Yes. It’s tested over 40,000 pull cycles, and the 3-jaw grip prevents the tilting and jamming that slows down high-load riveting.
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 5× the price.
