A right-angle driver for screws a normal driver can't reach
A long, slim driver with a 90-degree 7/64" hex pin, designed, prototyped and made in batches for a manufacturing client.
The challenge
A manufacturing client had small hex screws in places where a straight screwdriver or an Allen key could not be lined up. They needed a long tool with a thin head that could reach in and turn the screw from the side.
Our process
- Built a first prototype: a printed head on a long shaft, with the hex pin set at 90 degrees.
- Modelled the driver in CAD and drew up the hex pin: 7/64" hex end, 1 1/4" long.
- Put brass bevel gears on steel shafts so turning the shaft turns the pin, and seated them in printed heads closed with four screws.
- Added knurled grips and made the drivers in batches.
The result
The finished driver has a slim printed head with a 7/64" hex pin at 90 degrees, brass gears inside, and a long knurled shaft. After the prototype, the drivers were made in batches, and the photos show a dozen or more finished at a time.
