How to select the correct countersink for a flat-head screw?
Match the countersink angle to the screw head angle—82° is standard for inch flat-head screws. Ensure the body diameter exceeds the screw head, and the shank thread size (1/4"-28 for this APPROVED VENDOR model) fits your holder. Carbide construction provides durability in harder materials like steel or stainless steel.
