### ⭐⭐⭐⭐⭐ 10-24 caps
*by R***O on October 17, 2025*

They look good and worked perfectly

### ⭐⭐⭐⭐⭐ Used on a 2008 Tacoma 4.0 V6 intake cover
*by A***D on January 5, 2026*

I used them to replace the two missing acorn style nuts to hold down the plastic intake cover on my 2nd gen Tacoma (2008, 4.0 V6). They fit fine, but they aren’t as tall as the originals so you need to add washers to make up the space of the missing flange. Same thread pitch. M6-1.0
