💡 How do you install 1/4-20 threaded inserts into wood without cracking?

Proper prep is key - drill size matters based on wood hardness.

• Softwood: Use a drill bit between 8.5mm to 3/8" for easy thread cutting

• Hardwood: Go closer to the insert’s thread diameter (10mm or 3/8")

• Avoid overtightening - especially in hardwoods like oak and maple

• Hex drive tool ensures smooth alignment and control during install
