Perfect for fabrication

Used these for a custom exhaust mount. Welded cleanly without stripping. The projections melted evenly.

Good but tight threads

Carbon steel version works well. Threads were slightly tight on a few nuts but manageable with a tap.

Great bulk value

Ordered the M6 stainless ones. No rust after months outside. Highly recommend for outdoor equipment.
