DART CMD Assembly Lubricant is an extreme pressure lubricant built for the moment metal meets metal under load. Sold in a 4 oz tube, it is the kind of compound shooters, gunsmiths, and engine builders reach for when they need a film that holds up to high clamping force and frictional heat. It coats bolts, studs, nuts, and rod hardware during assembly to cut down on galling and scoring. If you maintain firearms or rebuild engines and want a single tube that handles the high-pressure contact points, this fits the bench. Browse the rest of our oils, fluids, and sealers for matched maintenance supplies.
The formula is rated to withstand pressures up to 50,000 psi per published specifications, which is what separates it from a general-purpose oil that breaks down the second a fastener loads up. Under that kind of squeeze it keeps a protective film between mating surfaces, reducing the metal-to-metal contact that causes galling and scoring on threads and bearing faces. Used as an assembly lubricant on threaded hardware, it also produces more accurate torque readings and higher clamping loads, since the consistent film removes the friction guesswork that throws off a torque wrench. The 4 oz tube dispenses cleanly for targeted application, and the universal formula works across fasteners, rod bolts, and general engine assembly. Compare it against our grease selection for heavier packing jobs.
Reach for this tube when you are torquing critical fasteners and need the reading to mean something, or when you are setting rod bolts and main studs during a build and want to avoid thread damage on teardown. The same extreme pressure properties make it useful on any high-load contact point where a thin film of standard oil would wipe away. A 4 oz tube goes a long way since you only need a light coat on the threads. Pair it with a quality threadlocker for fasteners that need to stay put, or check our extreme pressure lube options for related applications.
Published specifications rate the formula to withstand pressures up to 50,000 psi. That extreme pressure capability is what keeps a protective film between mating surfaces under heavy clamping load, where a standard oil would wipe away and allow metal-to-metal contact.
Yes. When used as an assembly lubricant on threaded hardware, the consistent film reduces friction variability, which produces more accurate torque readings and higher, more repeatable clamping loads. That removes a lot of the guesswork when torquing critical fasteners.
It ships as a 4 oz tube. Since you only need a light film on threads and bearing faces, that volume covers a large number of fasteners and assembly jobs before you need a refill.
The universal formula works on bolts, studs, nuts, rod bolts, and general engine assembly, plus any high-load contact point where you want to prevent galling and scoring. It is built for extreme pressure lubrication during assembly and torquing.
That is its main job. The extreme pressure film reduces the frictional heat, galling, and scoring caused by metal-to-metal contact during assembly. It protects threads and bearing surfaces so hardware comes apart cleanly later instead of seizing.
