.187″ Folder Pivots

.187" Stailnless Pivots

Our pivots are machined to very tight tolerances of ± .0002″ (2 ten-thousandths of an inch).

These pivots are made from 416 stainless steel and heat treated full hard to approximately HRC 42.

All our pivots are professionally heat treated in a vacuum furnace. This leaves the pivots with a shiny surface.

Ream the blade pivot hole and liners with a .1875″ reamer. The blade will move freely on the pivot shaft. The raised area on the pivot shaft next to the head will press fit into the liner and prevent the pivot from spinning when adjusting the blade tension. If you are not using a reamer, buy one. You will never achieve tight tolerances using only a drill bit to make your pivot holes.

.187″ Pivot Screws


Our machined screws are machined to very tight tolerances of ± .0002″ (2 ten-thousandths of an inch).

The screw is #6 with 64 threads per inch. The high number of threads make it easy to adjust the blade tension. The thread is non-standard.

The Torx drive is broached into the screw. This means Torx bits fit with no slop unlike other drives that are machined rather than broached. Broaching costs more, but the result is a higher quality screw. Also available in black pivot screws.
