Review: Good quality. Great for most 3D printers... - Good quality and perfect for my 3D printing hobby.
Review: Great deal - Great screws for a great price, can’t beat it. They do come a little dirty or material from manufacturing comes off out the box but not a big deal. The lack of quality control is absolutely worth the price and what you get here. Wouldn’t hesitate to buy again.

### ⭐⭐⭐⭐⭐ 🔩✨ Strong Little Screws With a Big Lesson! ✝️
*by D***T on November 21, 2025*

These iexcell M4 x 10mm screws do exactly what they’re supposed to do — simple, sturdy, and reliable. I used them for a small project, and they held everything together without any issue. No stripping, no slipping, just solid performance. 💪🔧 But while I was tightening them in place, I couldn’t help but think about how even tiny screws make a huge difference. They hold things together quietly in the background… kinda like how God holds us together when life feels loose and wobbly. Colossians 1:17 reminds us, “In Him all things hold together.” These screws? ✔️ Strong ✔️ Consistent ✔️ Easy to use A great little pack of hardware — and a sweet reminder that even the small things matter when God’s hand is in the mix. 🙏🔩✨
