UNBRAKO M12 X 20 SOCKET SET KNURLED CUP POINT PACK OF 25

If you know set screws, you know that the tighter you can tighten them, the better they hold and the more they resist loosening from vibration. But there’s a limit to how much you can tighten the average socket set screw. If you’re not care-ful, you can ream or crack the socket, and in some cases, even strip the threads. So you’re never quite sure whether or not it will actually stay tight. With UNBRAKO set screws it’s a different story. A unique combination of design and carefully controlled manufacturing and heat treating gives these screws extra strength that permits you to tighten them appreciably tighter than ordinary screws with minimal fear of reaming or cracking the socket. this extra strength represents a substantial bonus of extra holding power and the additional safety and reliability that goes with it.
