Cap Screw, M4x16, Socket Head

The M4x16 thread matched perfectly on my 3536 lathe, which saved me from having to hunt down a specialty fastener. The socket head grabs a hex key securely without slipping, making installation quick and frustration-free.

Had a small scare with a stripped screw on my 3540 lathe's carriage stop — this M4x16 socket head cap screw slid right in with no wobble, and the hex socket felt precise in the driver, making torque a breeze.

Exact fit for the 3536 lathe’s cross slide, threads engaged smoothly without any binding. Kept a spare on hand, and it’s already saved me a trip to the hardware store.
