If you’re thinking about purchasing new automotive fasteners, you may be wondering which one is the better choice. The two are similar in many ways, but they have their own unique benefits. You can use either one depending on the application. The main differences between them are temperature resistance and fixture time. Here’s a quick rundown. If you’re in the market for some new automotive fasteners, red Loctite 272 is a great option.
Loctite 271
There are many differences between Loctite 271 and 272. The former is a permanent adhesive used for threaded assemblies. It takes approximately 10 minutes to set, and provides up to 2900 psi of shear strength and 200 psi of tensile strength. It comes in case packs of 10 and has an IDH number of 88442. Both threadlockers are rated for use in high temperatures, but there are some differences between them.
Two major differences between these products are viscosity and cure time. Loctite 271 requires a 24-hour cure time, while Loctite 272 can be used immediately. While both types are suitable for fastenings with a small diameter, Loctite 271 is less robust and will not form a tight seal when used on fastenings that are larger than one inch. Neither is as strong as epoxy, super glue, or other types of adhesives. While Loctite 272 will not break down in vibration, it does adhere to metal surfaces with excellent mechanical strength. Loctite 272 is an anaerobic threadlocker and can be used on a wide range of items.
Temperature resistance
Red Loctite 272 is the heavy duty adhesive formula for bolts and nuts, as well as turbo engine parts. It is also used in industrial machinery fasteners, as well as for filler tunes and crankshaft bolts. This lube can withstand temperatures up to 450 degrees Fahrenheit and is recommended for bolts with smaller thread gaps.
Two types of Loctite are available: the 271 and the 272. The former is slightly less viscous than the latter, which makes it feel like a thin gel. The red Loctite is generally used for bolts and fasteners that are 3/8-inch-to-one-inch in diameter. Its temperature resistance rating is 450 degrees Fahrenheit, but it’s recommended for smaller-sized screws and nuts.
Fixture time
The two Loctite red series differ in viscosity and performance. The red 271 has a much lower viscosity than the blue 272, which is characterized by a thicker consistency and higher strength. It has a shorter fixture time and is less soluble in water, but is still very effective in the majority of threadlocking applications. It is suitable for fasteners with a minimum diameter of three/8 inches and up to one inch. Both types offer good temperature resistance and can be used on bolts and other metal fasteners.
Red Loctite is a heavy-duty threadlocking compound that is used for turbo engine parts, industrial machinery fasteners, filler tunes, and crankshaft bolt joints. It is used on fasteners of any diameter and can be applied to both new and old engine parts. LOCTITE red 272 can also be used in the assembly of turbo engine parts, allowing them to be secured to the crankshaft. Because of its thicker consistency, it can fill up to 0.01 inch of thread gaps and is suitable for large threads.
