U-Bolt nuts rear axle

[Ralph the german]

Hi guys,

is this the right thread of the nut from the rear axle of my 90 Blazer full size ?
Working on traction bars today and need new nuts.

5/8" - 18 UNF 0,625 15,875 14,50 18 1,411

thanks

It's going to depend on the rear axle you're using. I know that the 14ff uses a 5/8"-18 nut but i think the stock axles used a 9/16" nut. Someone else will chime in and correct me if i'm wrong.

Have a 4" lift, d´nt know that this u-bolts are in same dimension as the stock.
But 9/16" cannot, they have an outer dia of 14.288 mm, my u-bolts have an outer dia of 15.8 mm I measured.

15.8mm/25.4 = .622" (.625=5/8)

15.8mm/25.4 = .622" (.625=5/8)

yes, that is clear, but do not know if it is an x18 UNF, or is it an M16x1,5 ? 90 Chevy get metric on much bolts.

5/8-18 = 18 threads per inch
