Thanks! Way back, no lines meant grade 3, so each line was a notch harder as in 3 lines meant grade 5, 5 lines meant grade 8. That's what the originals were. They are pretty big bolts. Kinda sad to see I paid so much for Chinese made bolts. NAPA sold them to me so I'm sure they're OK. Just, you know, wish NAPA still sold made in USA hardware, especially since I paid Made in USA dollars.
