1/4-20 x 1″ Threaded Inserts
1/4-20 Threaded insert x 1″ long . Extra long for thicker material. Made of cast zinc with a flange.
Drill a 5/16″ hole for the insert (soft wood like MDF – Larger for hardwoods). Do a test hole first!
Use the M6 wrench to tighten
Good for those screws you got from the good old USA
