مسامير رأس مقبس M3-0.5 × 16 مم | رأس زر مع محرك سداسي | ملولبة بالكامل | فولاذ مقاوم للصدأ 18/8 (1800 / عبوة)

Had a precision assembly project that needed exactly 1800 pieces, and these M3-0.5 x 16mm hex socket screws came through without a single stripped head. The 18/8 stainless steel seems durable enough for repeated use in my jigs.

Installed a full batch of these in a jig fixture and every single screw threaded smoothly without any binding. The 18/8 stainless finish looks clean and professional, and the hex socket drive holds the driver securely even in tight spaces.

Bought these for a small robotics project and the 18/8 stainless steel is noticeably more corrosion-resistant than the cheaper alloy screws I've used before. The fully threaded length made assembly a lot cleaner since I could trim them to exact depth.
