I bought some "M8 HIGH TENSILE SET SCREW BOLT BZP 8.8 GRADE + 2 WASHERS
- FULL NUT, DIN 933" on ebay, and while the bolts look OK I'm not at all sure about the nuts.
Some are marked "s 181", some "gr 181", some "a2-70" plus a logo.
The last are stainless nuts - but does anyone know what the heck the other markings mean?
What sort of nuts should be supplied with 8.8 bolts?
help!! am going nuts,
thx,
