I need to get a replacement spinner bolt for my 4" tru-turn spinner that I'm putting on my DA100. I know the length I need is 4" but I need to know thread size and bolt diameter please. Thanks

+1....

On a cautionary note; a 10/32 WILL fit and is what Tru-Turn sends out (I asked 'em) but compared to the M5 x .8 it's a loose fit and I wouldn't use the SAE size.

since we are on the subject...........how about 3w80 prop bolts? ive changed props at least a dozen times, im scared im gonna break a bolt....im assuming the bolts weaken over repetitive tightening and loosening

Never saw a 5 mm Tru turn spinner bolt...5mm will go in, but very hard. The are .about .006 larger and different pitch..Small ones might be 5mm, the 6 inch ones we use are 10-32 and have always been. For the last 23 years. Maybe Dave is getting Bob to make him some special ones...
Good luck screwing a Good 5mm bolt into a Good 10-32 tapped hole...

Tru Turn provides SAE screws. If you want metric you're own your own.

For the spinner bolt 10/32 is fine. Its what tru turn supplys with their spinners and its been working for years.
