Frequently Asked Questions
Q: What sizes are included in this triangle screwdriver bit set?
A: The set includes five triangle bits with tip heights of 1.8mm (Δ18), 2.0mm (Δ20), 2.3mm (Δ23), 2.7mm (Δ27), and 3.0mm (Δ30), covering the most common triangle-head screw sizes used in electronics, appliances, and furniture.
Q: Are these bits compatible with standard power tools?
A: Yes. All five bits feature a universal 1/4" (6.35mm) hex shank, making them compatible with most electric screwdrivers, cordless drill drivers, pneumatic screwdrivers, and any tool or bit holder that accepts a 1/4" hex shank.
Q: Why are S2 steel screwdriver bits better than standard steel bits?
A: S2 alloy steel is a shock-resistant tool steel specifically engineered for screwdriver bit applications. It offers superior toughness and hardness compared to standard chrome-vanadium or carbon steel, meaning these bits are less likely to strip, crack, or wear down during intensive use.
Q: Are the tips magnetic?
A: Yes. Each bit is magnetized to attract and hold triangle-head screws in place, making one-handed driving easier and reducing the risk of dropping fasteners during installation or assembly work.
