برغي رأس سداسي داخلي 6 مم × 40 مم

Ordered a pack of these to replace a few worn ones on my equipment, and the 6mm x 40mm size was exactly right—threads were clean and they seated perfectly. They feel solid and haven't stripped on me yet. Glad I found a place that sells just the individual parts.

Had to swap out a stripped screw on my equipment and these 6mm x 40mm socket heads fit like they were made for it. The hex drive seated perfectly without any wobble.

The threads were clean and precise, making them easy to drive into the pre-tapped holes without any binding. For a replacement part, the hex socket drive felt solid and didn't strip even with my impact driver.
