Fastening Tools
(Also known as Pneumatic Fastening Tools / Air-Powered Assembly Tools)
Fastening Tools are pneumatically driven tools designed to tighten, loosen, or install fasteners such as bolts, nuts, screws, and rivets using compressed air power. They are essential in assembly lines, automotive repair, aerospace manufacturing, and heavy-equipment maintenance, where speed, consistency, and reliability are critical. These tools convert the energy of compressed air into rotational or impact torque, enabling precise and repeatable fastening operations — from delicate electronics to large structural bolts.
Working Principle
Air Supply: Compressed air enters the tool through an inlet.
Motor Drive: The air drives a rotary vane motor or piston mechanism, producing mechanical rotation or impact.
Torque Application: The motor’s output applies controlled torque or percussive force to a socket, bit, or riveting mechanism.
Control & Regulation: Built-in regulators or external controllers adjust torque levels, ensuring accuracy and repeatability.
