Industrial Grade High-Quality Pneumatic Riveting Nut Gun Kit with SELF-LOCKING GUN HEAD The Pneumatic Rivet Nut Gun is suitable for all kinds of metal plates, pipes, and other fastening industries in the manufacturing industry. PACKAGE INCLUDED: 1 * Pneumatic Rivet Nut Gun1 * Hanging Ring1* 1/4" gun head + 1 * Bearing + 1 * Hex Connecting Rod + 6 * Mandrels1* 5/16" gun head + 1 * Bearing + 1 * Hex Connecting Rod + 6 * Mandrels1* 3/8" gun head + 1 * Bearing + 1 * Hex Connecting Rod + 6 * Mandrels Multiple Self-locking Gun Heads Comes with 1/4, 5/16, 3/8 gun heads as well as 6 mandrels of each size. Quick and easy to change the gun head without tools due to the self-locking design. Air Inlet/Running Speed Adjusting Knob The work intensity and running speed can be changed by the air inlet adjusting knob so that you can choose the appropriate working speed. Embedded Muffler Vent The embedded muffler effectively reduces the noise generated during work(≤65db) and avoids the loud noise causing damage to the ears. High Hardness Cr-Mo Steel Mandrel The mandrel is consumables. The mandrel wears out as product usage frequency increases. Regular application of industrial lubricant can reduce wear on the mandrel.Not only did we prepare 6 wear-resistant mandrels for each gun head, but we also pre-assembled the gun heads and smeared them with industrial lubricant, so that you can use them directly after you receive them. Note & FAQ: Note: Our screws(mandrels) size are true imperial fractional size, not a metric converting size. FAQ: Q1. Why are some of your screws soft and some hard? A: The screws(mandrels) we provide are all Grade 12.9 Socket Cap Screws (hardened to HRC 39-44, 1100MPa minimum yield strength, and 1220MPa minimum tensile strength), which are harder than most conventional screws and are suitable for pulling aluminum nuts and iron nuts. The screws are consumables. So when pulling the nut, just pull it in place and stop and exit. If you pull too far, it will accelerate the wear. When connecting the air compressor, the input air pressure of the nut gun is recommended to be stable at 87-116PSI. If the air pressure is set too high, it will damage the screws, which is where most people make mistakes.

SELF-LOCKING GUN HEAD Comes with 1/4, 5/16, 3/8 gun heads as well as their 1 bearing & 6 mandrels of each size. Quick and easy to change the gun head without tools due to the self-locking design.

LONG PERFORMANCE LIFE The mandrel, bearing, and connecting rod are all made of high hardness alloy steel, and we have added Industrial lubricant to the gun head to make the rivet nut gun more accurate, more wear-resistant, and longer in service life.

ERGONOMIC DESIGN Small and light gun-like shape, non-slip handle and shock-proof design make it easier and more comfortable to use for long periods of time with one hand.

POWERFUL FUNCTION Air regulating valve, adjust work intensity and speed. Muffler to reduce noise. The 1/4 air inlet port with a built-in dust filter can effectively prevent foreign objects from entering the body and protect the internal parts of the nut gun.

NOTE The mandrel is a consumable item, and bearings and industrial lubricants can extend its life. We also provide 6 mandrels for each gun head so you can use it longer.
