Button Head vs Socket Cap Head
⚠️ Important Consideration
Button heads have lower load capacity than standard socket cap screws due to reduced head height and socket depth. For maximum clamping force, use ISO 4762 socket cap screws. Choose button heads when aesthetics and low profile are priorities over maximum strength.
