J/E stainless steel lower mount bolts

[93bronco]

after looking at the 4 lower mount bolts - i found all 4 twisted.< off my 120/140><br />so are SS bolts of the same strength or do they vary like regular bolts?<br />i found some with no lines on top of head & some with 2 lines on top of bolt head.<br />ace hardware says they are of the same strength & that its the manufacture trade mark.<br />is this true?

2K,<br />Not all SS bolts have the same strengths. Common grades are 18-8, 316, 304. The intended application will determine the grade and mechanical properties of any one fastener.<br /><br /> http://www.askzn.co.za/tech/tech_grades.htm <br /> http://www.unified-eng.com/scitech/bolt/boltmarks.html <br /><br />This is an interesting read, kinnda long winded but informative.<br /> http://www.289register.de/boltse.html
