براغي تثبيت ذات نقطة مسطحة M4 × 16 مم بمقبس سداسي | فولاذ مقاوم للصدأ 18/8 (500/عبوة)

Finally found set screws that don't strip out even when I crank them down—the 18/8 stainless steel is definitely tougher than the cheap zinc ones I used before. Perfect for locking a gear onto a shaft in my 3D printer.

The 18/8 stainless finish looks clean and professional on my machine build, and the flat point seats perfectly without marring the shaft. 500 pieces for this price means I won't run out mid-project, and the hex drive bites firmly even in awkward angles.

The hex socket drive really makes a difference when you're working in a cramped spot. These screws feel solid and the finish is clean.
