DEPRAG Precision Automatic Screwdrivers

Adjustable Torque Screwdrivers

Hand held and machine mounted precision screwdrivers (automatic screwdrivers). Deprag's torque screwdrivers are available in pneumatic or electric drive and feature robust, ergonomic design as well as being highly accurate. All of the screwdrivers have an accuracy of ±3% standard deviation or better.

Screw assembly is an often overlooked part of an assembly. Correctly designed screw joints, the correct screws and torque setting are essential to achieve a quality product. Missing or incorrectly torqued screws are a leading cause of product failure and can cause costly warranty repairs. Deprag offer the most accurate torque controlled screwdrivers and automatic screwdrivers on the market as well as proven solutions to quarantee a quality assembly.

Screw Feeders

Deprag also specialises in auto feed screwdrivers, screw assembly machine, and automatic screw feeding machines however they can manufacture the feeders to suit most kinds of small parts. We can feed screws or parts to a hand guided screwdriver or press in device though a hose as well as to machine mounted equipment. Our feeders are available in various sizes with either a vibratory drive or a sword feeder.

Pneumatic air hacksaws are the tool of choice when materials need to be cut in hazardous areas such as oil & gas refineries, chemical factories or oil rigs as well as dusty and wet environments where electric tools are not reliable enough.

Air hacksaws are also valuable tools in production environments such as pallet repair, shipbuilding or fiberglass workshops beacuse they will last longer than electric tools especially in dusty or wet environments.

Automatic Screwdrivers and Precision Assembly Solutions
FAQs

What are automatic screwdrivers used for?: Automatic screwdrivers are used in production and assembly environments where fast, repeatable and accurate fastening is required. They help improve consistency, reduce manual effort and support better torque control across repetitive screwdriving tasks.

What is the difference between a torque screwdriver and a standard screwdriver?: A torque screwdriver is designed to apply a controlled amount of torque during fastening, helping reduce under-tightening or over-tightening. This is especially important in precision assembly, electronics, medical devices and other applications where fastening accuracy matters.

When should I use a screw feeder system?: A screw feeder system is ideal when operators need to fasten screws quickly and repeatedly with less handling time. Screw feeders can improve productivity, streamline workflows and support better consistency in repetitive assembly operations.

What industries use air motors?: Air motors are commonly used in manufacturing, processing, hazardous-area applications, maintenance operations and environments where pneumatic power offers advantages over electric drive systems. They are valued for durability, compact performance and suitability in demanding conditions.

Do you supply and support customers in Australia?: Yes. Assembly Technologies supplies industrial fastening and pneumatic tooling solutions for Australian businesses and provides local product knowledge and support. We work with customers across Australia to help specify the right equipment for their application, production requirements and operating environment.
