Spring Pin, M3x20

The pin dropped straight into my tailstock with zero wobble, which tells me it's dimensioned properly for the SC4. Spring tension feels right too, quill returns smoothly instead of sticking like the worn one did.

Fits my SC4 tailstock perfectly, no filing or fiddling needed. The M3x20 sizing was spot on and it slid right into the quill bore. Genuine part, so I'm not worried about it snapping like the hardware store one did.

After my old pin snapped mid-project, this replacement slid in with no filing or fiddling needed on the 8.5 x 20. The M3x20 sizing is dead on and the spring tension feels right when the tailstock quill retracts. Back to turning the same afternoon.
