What is MJ profile?

The MJ profile thread is a hard metric version similar to the UNJ inch standards, ANSI/ASME B1. 15 and MIL-S-8879. The MJ profile thread has a 0.15011P to 0.180424P controlled root radius in the external thread and the internal thread minor diameter truncated to accommodate the external thread maximum root radius.

What are MJ threads?

MJ threads are “Metric threads for Aerospace” used in aircraft, rockets and space stations. The MJ thread standard is specified in ISO 5855. The minor diameter is larger and the pitch diameter tolerance is more strict than general Metric threads.

What does Mjthreads stand for?

MJ THREADS – Myocardial infarction, Jaundice, Tuberculosis, Hypertension, Rheumatoid arthritis, Epilepsy, Asthma, Diabetes, Stroke.

What is a 10mm thread?

10mm is . 3937″ in decimal measurement. A 10mm brake line nut will measure 9.8mm or . 382 of an inch. A thread pitch gauge is needed to measure threads accurately.

Is 5/16 The same as M8?

Well, quick answer is no. They are not the same and they are not interchangeable, although they can work under certain circumstances. The most important part is understanding the meaning of M8 and 5/16 to refer to the size of a metric screw or bolt, so then we can see why they aren’t the same thing!

What are the dimensions of an MJ profile thread?

The MJ profile thread is a hard metric version similar to the UNJ inch standards, ANSI/ASME B1.15 and MIL-S-8879. The MJ profile thread has a 0.15011P to 0.180424P controlled root radius in the external thread and the internal thread minor diameter truncated to accommodate the external thread maximum root radius.

Is the MJ thread compatible with the UNR thread?

However, M external threads are compatible with M and MJ internal threads (just as UN and UNR external threads are compatible with UN and UNJ internal threads). You must log in or register to reply here. Thread Tolerance – Can I use a 3A Ring on a part that the drawing calls out for a 2A?

What is the metric fastener thread profile m?

Metric fastener thread profile M is the normal, commercially-available thread profile.

What kind of threads are used in aerospace?

ISO 965-1 Aerospace Standard MJ Threads The MJ screw thread is intended for aerospace metric threaded parts and for other highly stressed applications requiring high temperature or high fatigue strength, or for “no allowance” applications.
