براغي قطع خيط من النوع F #6-32 × 1/4 بوصة | رأس غسالة مسننة سداسية | فولاذ مؤكسد أسود (100/عبوة)

The indented hex washer head really helps spread the load on thin sheet metal, which is exactly what I needed. Thread cutting into 18-gauge steel was smooth and the black oxide finish adds a nice corrosion-resistant touch. These cut clean and hold firm.

The hex washer head sits perfectly flush, making these screws ideal for load distribution on my metal brackets. They drive in smoothly and the black oxide finish looks clean. Exactly what I needed for a sturdy fastening job.

The black oxide finish on these screws seems to grip better than the plain zinc ones I used before, and the indented hex washer head sits flush without chewing up the surface.
