Pneumatic Rivet Nut Gun Industrial Automatic Hydraulic Pull Rivet Nut Tool Pneumatic Riveting Gun Set M3-M12

Key Differences Explained

1. A vs. B Suffix (for 0312/5312 Series)

A Models: Single-threaded design,Wrench required for gun head/drawbar replacement,Lower cost.
B Models:Double-threaded design,Tool-free maintenance,Higher cost (prioritizes convenience).

2.Reverse Function:

Supported in: 5312A, 5312B, 5308F,Enables quick withdrawal of jammed nuts during riveting abnormalities.
Not supported in: 0312A, 0312B, 5308,Requires manual unscrewing of stuck nuts.

3.Riveting Range:

5308/5308F: Medium nuts only (M4–M8).
0312/5312 Series: Full range (M3–M12), suitable for small to large nuts.

The operation is simple
1.Put the screw nut, rivet nut sensed a light pressure.
2.Riveting nut, after induction to automatically rotate the nut inlet.
3.After rotating the air inlet, pull the trigger and pull the rivet nut gun backward to deform the nut.
4.Trigger continue not to put, nut after deformation, automatic gun exit from the nut, to complete a job step.
