![]() Stress and strain on the parts themselves. That metal-on-metal contact puts a lot of Even with oil, all of those pistons, rods,Ĭylinders, and valves are rubbing up against each other. Metal parts in your engine have to work together. In order for you to drive across town to work, all of the ![]() Schaeffer's has even patented their brand, Micron Moly®.īecause Moly's friction-reducing capabilities are a huge deal! It's easy to underestimate how harmful friction can be, so let's look at it from your engine's perspective… ![]() This form of moly is 100% oil-soluble which allows it to remain suspended in the motor oil and provides all the benefits of MoS2. The most common moly type used in today’s moly oil formulations is Molybdenum Dithiocarbamate or (MoDTC). However, most premium oil formulations (like Schaeffer's) no longer use MoS2 in their motor oils because it does not stay in suspension. Over the years, Moly oil has become one of the premium types of oil on the market. Use the term "Moly oil," they're talking about a lubricant that has had Moly added to it. Result, moving parts can move more easily, without causing nearly as much wearĪnd tear as they would if the Moly wasn't there.īecause it's so good at reducing friction, Moly has become aĬommon additive to oil. That coating effect reduces the amount of It's made up of microscopic particles that are great at coating metallic surfaces. Molybdenum disulfide is an inorganic compound that is composed of molybdenum and sulfur. Even though it's solid, In the lubrication world, Molybdenum disulfide (MoS2) is a compound used as a dry lubricant. Products - because it's so much more durable. You have probably heard of "chrome-moly." With it, manufacturers can use less steel -and, thus, make lighter It's used as an alloying agent to make steel Molybdenum all by itself is a tough metal that has many industrial It looks similar to graphite, but it's not the same thing. Consider this to be your crash course in all things Moly …įirst things first. You can read about the entire history by clicking here. Similarly, over-torquing can stretch fasteners beyond their ability to continue creating tension (they lose their elasticity) which can lead to thread binding.Moly has been used in lubricating oils and greases forĭecades, but unless you're a tribologist, you probably don't know what Moly oil is or even what "Moly" stands for. Nylon insert lock nuts paired with stainless steel is a common troublesome issue.ĭirt and nicks on threads create friction and, in turn, heat. So avoid them, or install them very slowly. Lock nuts like these are designed to add resistance when installed and generate lots of heat. Thread galling is excessive mechanical contact between mating surfaces. Generally, the softer the metal, the more apt it is to gall. Example: use a type 304 stainless steel nut with a type 316 bolt. Metal grades have different hardnesses and when mixed, can stop galling. Mix nut and bolt grades while maintaining mechanical properties Thread rolling photo courtesy of Horst Engineering/Thread Rolling Inc. Lathe-cut bolts typically have rougher threads which create more heat when coupled with nuts that usually have tapped threads. Ordinary bolt threads are rolled between dies, which produce relatively smooth surfaces. ![]() The slower the power tool speed, the less heat is generated and the less likely galling will occur – during installation and removal. So, control speed when using powered equipment, or use hand tools where galling may occur.įine threads can have more surface area and their thread clearance may be reduced. Other remedies include Loctite and Aero-Chem® lines of anti-seize products. They include PTFE, commonly referred to as Teflon, PVDF, PFA, and FEP. Fluoropolymer coatings are also effective. Brand names include Perma-Slik® RAC, Xylan, and DELTA® SEAL. Pre-applied or applied on-site, dry film lubricants or lubricants rich in molybdenum disulfide (moly), graphite, mica, talc, and even extreme pressure waxes are effective at reducing friction. ![]()
