Fluorokote #1 Torque Information

Fluorokote #1 was designed with torque values in mind. That being said a multitude of factors can change the torque values, especially inconsistencies in the fastener itself. It is important to test any fastener before it goes into service, regardless of the coating. Furthermore, Lubricants also affect the torque values of a fastener. A common question we get is “What lubricant should I use with Fluorokote #1?” and a lot of the time, the answer is more complicated than simply whatever lubricant you have lying around. PTFE-based coatings are technically self-lubricating. The PTFE works its way out of the coating during installation, and that's where the "you don't need anti-seize" assumption originally came from. But PFAS compliance has changed that math. As PTFE content gets reduced to meet current PFAS requirements, that self-lubricating effect can't be assumed the way it used to be. On top of that, API and other industry bolting standards require thread lubrication regardless of coating. Our position: don't just grab any anti-seize off the shelf, test it against the coating first. Not every lubricant is compatible, and the wrong one can break down the coating itself. If you're specifying a lubricant for coated fasteners, confirm it's been tested against the specific coating, not just assumed compatible.”
