Common heads
Pan, countersunk, round, socket, hex and flange heads — each affects tool access, seating and appearance.
Common threads
Self-tapping (drilling) threads suit sheet metal, wood and drywall; machine threads match nuts or tapped holes per standard.
Quick pick
Choose head by application and thread by connection method; send a photo if unsure and we'll confirm.
