Hex bit driver for 3.5mm jack knurled nuts - Knurl Kontrol - precision engineered 1/4" stainless steel bit

The 3,5mm knurled nut may at first appear a challenging piece of hardware to fasten - you may already have tried tape-wrapped pliers and screwdrivers contorted into new shapes with an angle grinder, but none of it will compare to the mighty Knurl Kontrol bit from Herzlich Labs.

With a 1/4" hex shank, it fits your preferred bit holder, allowing you to use it with ratcheting tools when speed is required, or torque wrenches when precision is of the utmost importance. The Knurl Kontrol is precision engineered in stainless steel and designed to stand up to continued use in manufacturing environments - even with more than a thousand bits sold, we have yet to receive a single report of one breaking in use.

The Knurl Kontrol fits all standard 3,5mm knurled nuts - in fact, we have yet to come across a knurled nut it would not safely drive. The long barrel, centering pin and driving pins reduce the risk of slippage, wobble and make alignment both fast and easy.

When we designed the Knurl Kontrol, we wanted to bring about a tool that would fit equally well in continuous, intensive and demanding manufacturing environments, as well as with synthesizer and DIY enthusiasts in mind. For that reason, we are proud to see the Knurl Kontrol in use across industries, including high-end stage equipment, electronic music manufacturers, Academy Award winning performers, psychedelic rock legends, medical equipment manufacturing, aviation engineering, broadcasting and the US Navy, to name a few.

If you work with 3,5mm knurled nuts, professionally or privately, the Knurl Kontrol is a safe and reliable choice for your workshop, and will save you time, frustration and scratched front panels during both assembly and disassembly.
