SAE J995
SAE J995 covers the mechanical and chemical requirements for inch series nuts in three grades used in automotive and related industries in sizes to 1-1/2” inclusive. SAE J995 Grades 2, 5, and 8 nuts are readily available in a standard hex pattern.
| Grade | Nominal Size, inches | Proofload, UNC and UN 8 Threads, psi | Rockwell Hardness |
|---|---|---|---|
| 2 | 1/4 thru 1-1/2 | 90,000 | C32 Max |
| 5 | 1/4 thru 1 | 120,000 | C32 Max |
| Over 1 thru 1-1/2 | 105,000 | C32 Max | |
| 8 | 1/4 thru 5/8 | 150,000 | C24-C32 |
| Over 5/8 thru 1 | 150,000 | C26-C34 | |
| Over 1 thru 1-1/2 | 150,000 | C26-C36 | |
| *Values listed are not normally applicable to jam, slotted, castle, heavy or thick nuts. | |||

| 1-1/2-6 | 1.405 | 1-1/2-8 | 1.492 |
| To calculate individual nut proofload value, simply multiply the tensile stress area by the appropriate psi proofload value. | |||
Burned Converters Are A Thing Of The past!
This is a very common issue that we have been facing since the late 90′s. It would be more common on on the heavier vehicles like th Odyssey and the Accord V6. But you would aslo see it on the 4 cylinder Accords as well. Although there was a lot of changes and updates to the torque converter, the problem remained. Well, her is a solution for this particular problem. Hope this will help you.

Time lapse of 3D printed “BIG Nut And Bolt”. Time lapse taken from my Octoprint server attached to my Printrbot Simple Makers 1405 using the standard Raspberry Pi camera and a wide angle clip on lens.
A very cool print to make and great to show off to people. Very satisfying to spin the nut on and off! Had to screw it on and off a couple of times to loosen up the thread so it was smooth – could also put some silicone sealant on it to make it even more smooth, but it doesn’t need it.
Scaled it down to about 60% for it to fit into my printer upright. Would love to print this full size or bigger as a great novelty item and showcase as to what can be 3D printed.
An oddity of the design from an engineers point of view if this was a functional piece is that the nut has a different size hex to the bolt head, so you would need two different spanners to fasten this nut and bolt, or a pair of adjustable one?!

Print Settings Below:
Filament: Printed using 3D Prima 1.75 PLA – Dark Grey
Filament used: 10.844m 32.0g
Layer Height: 0.2064mm
Temperature: 210°C
Perimeters: 2 at 0.4mm (0.8mm total)

Still trying to get a better set up for my time lapses. Think the built in Raspberry Pi camera is not suited and I may have to set up an external camera – comment below if you have any tips or suggestions?!
