Frequently Asked Questions
Q: What sizes are included in this Torx security bit set?
A: The 13-piece set covers T7, T8, T9, T10, T15, T20, T25, T27, T30, T35, and T40 sizes, giving you a broad range for repairs on electronics, appliances, motorcycles, and more.
Q: What is the difference between a standard Torx bit and a hollow (security) Torx bit?
A: A security Torx bit has a center bore (hole) in the tip, allowing it to engage tamper-resistant Torx screws that have a pin in the center. Standard Torx bits cannot fit these pin-in-socket fasteners. This set includes hollow security bits for that purpose.
Q: Will these bits fit my cordless drill or impact driver?
A: Yes. The 1/4-inch hex shank is the industry-standard size compatible with the vast majority of cordless drills, impact drivers, ratchets, and manual bit holders.
Q: Are these bits magnetic?
A: Yes, the tips are magnetized to help hold screws in place while working, which is especially helpful in hard-to-reach areas or when working overhead.
