Customer Reviews (4.8 / 5 · 5 reviews)

Hazel Q. ★★★★★

The silicon bronze material gives these screws a solid, premium feel that standard steel just can't match. They threaded into my jig perfectly without any binding or cross-threading issues.

Joshua ★★★★★

The hex socket drive fit my Allen wrench perfectly, and these silicon bronze screws feel much more corrosion-resistant than standard steel. I used them for a small jig project and they threaded smoothly without any binding.

Henry ★★★★★

I was pleasantly surprised by how cleanly these silicon bronze screws drive in—they don't gall like stainless often does on my boat hardware. The fully threaded length was perfect for the jig I was assembling.
