Review: Worth the quality you get! - Best Ive tried yet! They get a great bite with the thread. With proper heat press temp settings, press time and the right size hole Im able make 3d prints look factory official with them. Havnt had 1 strip or not fit a screw, unless I misaligned it when pressing. I have m4-m8 stocked
