Inline Pneumatic Screwdrivers for Industrial Assembly — Overview
Inline Pneumatic Screwdrivers deliver precise, repeatable torque with an ergonomic in-line grip that keeps force on the fastener axis. Under the TUNGLIH brand, Dongli Industrial Equipment (Shenzhen) Co., Ltd. manufactures adjustable-torque air drivers for continuous use, with options up to 80 Nm. These tools support automotive, electronics, appliances, furniture, and general mechanical assembly where throughput and quality matter.
Product Range: Push-to-Start and Lever-Start Inline Pneumatic Screwdrivers
Choose activation style and clutch type to match joint conditions and station layout. Options include shut-off clutches for high repeatability and non shut-off (slip) clutches for soft joints and cost-sensitive tasks.
Push-to-Start Inline Pneumatic Screwdrivers
Best for fixture-supported stations and automated screw feeding. Push-start simplifies cycle initiation, reduces hand movement, and pairs well with shut-off clutches for hard and medium joints.
Lever-Start Inline Pneumatic Screwdrivers
Ideal when precise bit placement is critical or joint conditions vary. The lever prevents accidental starts and gives fine control on delicate assemblies and mixed fastener sizes.
Key Features of TUNGLIH Inline Pneumatic Screwdrivers
Adjustable torque ranges cover delicate to heavy fastening. The in-line grip improves axial control and reduces fatigue. One-hand forward/reverse, air-efficient designs, and in-house spare parts support uptime. OEM/ODM customization helps align tools with feeders, torque arms, and station fixtures.
Applications & Industries for Inline Pneumatic Screwdrivers
Use these inline air screwdrivers for plastics, light alloys, and steel joints requiring consistent seating torque. Typical applications include electronics housings, appliance assemblies, interior trim, seat systems, metal frames, and sub-assemblies across multi-shift production.
Selection Guide and Clutch Comparison for Inline Pneumatic Screwdrivers
Define torque window, fastener size, joint type, and cycle time. Balance free speed with seating control. Ensure stable air with proper filtration, regulation, and lubrication.
| Clutch Type | How It Works | Best For | Key Benefit |
| Shut-off | Cuts air at preset torque | Hard/medium joints; quality-critical stations | High repeatability; reduced rework |
| Non shut-off (Slip) | Clutch slips to limit torque | Soft joints and mixed materials | Economical; smoother seating |
Accessories & Integration for Inline Pneumatic Screwdrivers
Enhance performance with automatic screw feeders, torque arms, and balancers. Use FRL air prep for consistency. In-house bits, sockets, and maintenance kits support long-term reliability.
