※ Above is explanation for M5 screw

Alloy steel material + Heat-treated screw strength is grade 10.9
Overall improvement in strength prevents easy damage to the head

Screw shape comparison (cross-section)

Hexagonal hole

Hexagonal groove is deep, so thickness is thin
Small hexagonal hole width

Cross hole

Feature 1: Cross groove has thicker pre-reserved thickness, Head part is not easily damaged
Feature 2: Cross hole can withstand large brake torque
