14pcs Torx Security Bit Set T5-T40 with 1/4" Adapter

14pcs Torx Security Bit Set for Precise, Reliable Fastening

- This 14-piece Torx screwdriver bit set with center hole is designed for accurate, consistent performance on standard and tamper-resistant Torx screws. Covering sizes from T5 to T40 and supplied with a 1/4 inch adapter extension rod, it provides dependable control for electronics, automotive, appliance repair, and general workshop use.

Each bit is manufactured from alloy steel and induction hardened for wear resistance under repeated use. The 25 mm length is suitable for close control in handheld or powered tools, while the sandblasted surface helps reduce slip in the chuck and improves corrosion resistance. The set includes 13 Torx bits with center hole in the following sizes: T5, T7, T8, T9, T10, T15, T20, T25, T27, T30, T35, T40, plus a 1/4 inch adapter extension rod. All bits use a 6.35 mm (1/4 inch) hex shank, making them compatible with most electric screwdrivers, rechargeable screwdrivers, and many pneumatic drivers that accept standard 1/4 inch hex accessories. The included adapter extension rod provides additional reach for recessed or hard-to-access fasteners and allows quick bit changes. This combination of security Torx profile and standard shank interface makes the set suitable for tasks such as opening electronic housings, working on vehicles and machinery, and assembling or maintaining equipment that uses Torx security screws.

FAQ

Q: Are these bits suitable for security Torx screws with a pin in the center?
A: Yes. Each Torx bit is manufactured with a center hole, allowing use on tamper-resistant Torx screws that have a security pin.

Q: Which tools are these bits compatible with?
A: The bits have a 6.35 mm (1/4 inch) hex shank, so they fit most electric screwdrivers, rechargeable screwdrivers, and many pneumatic screwdrivers that accept standard 1/4 inch hex bits. The included 1/4 inch adapter extension rod also works with compatible socket or bit holders.

Q: Can I use this set for both light electronics work and heavier mechanical tasks?
A: The smaller sizes (such as T5-T10) are well-suited to electronics and precision assemblies, while the larger sizes (up to T40) are appropriate for many mechanical, automotive, and equipment fasteners, provided you stay within normal torque limits for the bit size.

Q: Is the length of the bits fixed, and how long are they?
A: Yes, each bit has a fixed length of approximately 25 mm. For extra reach into recessed areas, use the supplied 1/4 inch adapter extension rod.
