براغي رأس سداسي ثقيل 1-1/4-7 × 3" | ستانلس ستيل 18/8 | ملولبة بالكامل (2/عبوة)

Needed these to bolt a machine base down and the threads cut clean with no galling, even after a few test fits. The fully threaded shank was handy since my hole depth varied a bit. Heavy heads torqued down solid.

These went on a trailer hitch rebuild and the stainless threads cut clean with no galling, even without chasing them first. The 1-1/4-7 size fits standard heavy hex nuts perfectly, and the heads take a big impact socket without rounding.

The 1-1/4-7 thread fit my equipment's mounting holes perfectly with no cross-threading. Only reason it's not five stars is the two-pack sizing — I needed three and had to order twice.
