7 قطع M3-M12 الخيوط Rivnut مغزل M3 M4 M5 M6 M8 M10 M12 ل متري اليد الجوز برشام
looks very sturdy but unable to see them function properly as the thread sizes are different from my cheaper system but will give it a good tryout when the new hand Rivnut arrives
Very good and fast shipping
Thank you so much
