When you’re assembling vital and high-stress components, fasteners need to fall within a prescribed toque spec to ensure repeatability and reliability. Not only can nuts and bolts loosen or back off of a critical part but having an inconsistent torque spread can pull precision parts out of alignment, create warpage and even lead to failures.

Consider the head studs, rod caps, or main caps in an engine, these are the most highly stressed pieces of hardware in an engine and they create sealing surfaces, maintain bearing journal clearances and more. If you don’t know how consistent your torque settings are, you need to re-evaluate.

ARP has scatter plots showing the range of torque values using different thread lubricants.

ARP is a leading manufacturer of performance fasteners, and with the pride they put into making their bolts they want end-users to get the full potential out of them. That means proper usage and torquing procedures. Most of us are familiar with using some form of oil, anti-seize, molybdenum-based lubricant or other thread compound to ensure hardware does not bind, gaul or reflect an in-accurate torque rating.

ARP has gone the extra mile in developing a compound to exceed the performance of all the aforementioned compounds. Ultra-Torque Fastener Lubricant is designed to help provide the most repeatable toque settings across a family of fasteners. Check out the data and testing contained in the video and next time you assemble an engine, or other high-stress part consider what you are using to make sure your toque values are correct.
