Bulk M4 Flat (Countersunk) Socket Cap Screws – 12.9 Alloy Steel, Black Oxide
Flat head screws are used in machine parts, die fixturing, and especially common for removable panels and parts. Flat Heads are fully countersunk, so they become flush when installed. These are most often used for assembling close tolerance machinery where head clearance is critical.
