#2-56 × 1" براغي مقبس سداسي | رأس مسطح فيليبس درايف | صنع في الولايات المتحدة | كامل الخيوط | سبيكة فولاذ أسود مؤكسد حراريًا (100 / عبوة)

These fit perfectly into a precision jig I’m building for watch repair, and the hex drive holds the Allen wrench without any wobble. The black oxide finish seems tough enough to resist a bit of oil and handling on the bench.

Box arrived with all 100 screws cleanly packed, and the black oxide finish looks consistent across the batch. Threads cut smoothly into my aluminum fixture without any binding, though a couple needed a quick tap to clear slight burrs from the plating.

Used these to fasten a small jig on my mill, and the flat head worked well for countersinking. The 1" length was just right for the application. Only wish the package came with a few extra in case I drop one.
