“KARAT” Featured New Products

1. High Quality ANS-80 Industrial Grade Pneumatic-Hydraulic Rivet Nut Tool, Hand Spin-Pull-Hand Spin Type

ANS-80 provides excellent functions. Its powerful traction force can produce 10,600 N at 6.2 bar or 2,380 lbf at 90 psi compressed air pressure, and 12,000 N at 7.0 bar or 2,700 lbf at 100 psi compressed air pressure. It has an adjustable stroke of 0-7mm to provide accurate fastening.

In terms of its design, it has interchangeable threaded mandrels and nosepieces for installing M4 ~ M8 or # 8 ~ 5/16 rivet nuts made of aluminum, steel, stainless steel and other materials. It has optional threaded sockets for installing rivet bolts (studs) of the aforementioned sizes and materials. The hand grip is made of non-toxic PAHs-free soft plastic, and whole tool is compliant with EU RoHS and REACH SVHC requirements for environmental protection. It is shockproof and has the innovative noise silencer and twin air inlets. Its unique adjustable fastening speed allows users to install rivet nuts at a low speed to fasten paint-repaired car bodies or thinner work piece, plus the hand spin-pull-hand spin mechanism is designed for unscrewing the rivet nut from the fastened work piece to avoid damaging the paint-repaired car bodies or thinner work piece. It has the innovative fix-hole design to easily solve the nerve-racking problem of rivet nut stuck with the mandrel.

Its hydraulic cylinder and air cylinder are made of high-strength aluminum alloy with wear-resistant mirror finish on their inner surfaces. The piston rod has hard chrome plating and wear-resistant mirror finish to increase work efficiency and extend tool life. Other critical parts such as threaded mandrels are made of high strength alloy steel and go through advanced heat treatment for rigidity and durability.  

2. ARV-206 Industrial Heavy-Duty Pneumatic-Hydraulic Rivet Tool, with Vacuum System

ARV-206 has a stroke of 15.8 mm or 0.62”. Its powerful traction force can produce 14,700 N at 6.2 bar or 3,300 lbf at 90 psi compressed air pressure. It can easily set 3.0/3.2 ~ 6.4 mm or 1/8 ~ 1/4 blind rivets made of aluminum, steel, stainless steel, etc., also can set most structural rivets. It has shock reducer  and noise silencer for comfortable operation. Its vacuum system can automatically suck the mandrel of blind rivet into working nosepiece, and eject the spent mandrel into the spent mandrel container after setting blind rivet. It comes with an oil refill hole for quickly refilling hydraulic oil, and a spent mandrel container to keep working area clean. It also equips with the patented Rivet Size Hole Gauge™ to eliminate choosing the wrong size of blind rivet and working nosepiece. The hand grip uses the same aforementioned non-toxic materials. The whole tool complies with EU RoHS and REACH SVHC requirements. The Tool comes with interchangeable nosepieces with size mark 3.2 ~ 6.4 mm (1/8 ~ 1/4).

As one of the greatest features, its hydraulic cylinder is made of high strength forged aluminum alloy with hard anodized finish, and its air cylinder is made of high strength aluminum alloy with powder coating finish, making the whole tool valuable looking and durable. The hydraulic cylinder, air cylinder and piston rod all go through the same aforementioned surface treatment. Other key parts like jaws and collet cases are made of high grade steel alloy and with advanced heat treatment for strength and durability. These together form the main characteristics of KARAT ARV-206 Industrial Heavy-Duty Pneumatic-Hydraulic Rivet Tool.
