Set Screw, M4x18, Socket Dog Point

The socket drive gave me a solid grip, and the M4 thread fit perfectly into my machinist fixture without any wobble. I'm really pleased with how precisely the 18mm length matched my hole depth—saved me from having to grind anything down.

The dog point sits perfectly flush in the threaded hole, making alignment a breeze on my milling jig. Socket drive grips firmly without any cam-out. Exactly the precision I needed for this repair.

Finally got a batch of these dog point set screws for the mill table, and the socket drive made installation with an Allen key much cleaner than slotted versions. The M4x18 length is just right for securing aluminum fixtures without bottoming out.
