Product Information
Full details
The Facom Torx Screwdriver Bit T40 (EX.140) is a professional-grade tool designed for technicians, mechanics, and DIY enthusiasts who require precision and durability in manual fastening applications. Its primary benefit lies in its high-quality construction which ensures a secure fit for T40 Torx screws, reducing the risk of cam-out during high-torque tasks. A key caveat is that this 25mm bit is specifically engineered for manual use; it is not intended for high-impact power tool operation, which may compromise the integrity of the bit tip.

FAQs
Can I use this bit in an impact driver?
No, this bit is designed for manual screwing applications and may fracture if subjected to the high-torque, percussive force of an impact driver.
Does this bit come with a magnetic holder?
No, the EX.140 model refers to the bit only; it does not include a screwdriver handle or magnetic bit holder.
Is this bit compatible with all brands of 1/4-inch drivers?
Yes, it is designed to standard industry dimensions for 1/4-inch (6.35mm) hex drives, making it compatible with virtually all major hand-tool brands.
How do I prevent the bit from rusting?
Keep it in a moisture-free environment. Wiping it with an oily rag after use can also provide a protective barrier against humidity.
Is the T40 size compatible with T40H (tamper-proof) screws?
No, this is a standard T40 bit. It does not have the center hole required for Torx tamper-proof screws.
Troubleshooting
Bit slips or cams out of the screw head
Verify that the screw is actually a T40 size. If it is, ensure the screw recess is clean and free of debris, and apply firm, consistent axial pressure toward the screw.
Bit keeps falling out of the screwdriver handle
Check your bit holder for a worn retention spring or magnet. If the bit shank is clean and undamaged, the issue is likely with the receiving handle rather than the bit itself.
Pros and Cons
Pros
- High-precision tip geometry prevents screw head stripping
- Universal 1/4-inch hex drive fits most standard bit drivers
- Compact form factor ideal for confined engine bays or electronics
- Durable build quality characteristic of the Facom brand
- Lightweight and easy to organize in standard bit rails
Cons
- Not rated for high-impact or heavy-duty power tool usage
- Short 25mm length may be inaccessible in very deep-set screw holes
- Requires a separate handle or bit driver tool to operate
Setup, Compatibility & Care
To begin, simply insert the 6.35mm hex end of the EX.140 bit into any standard 1/4-inch bit holder or ratcheting handle. Ensure the bit is seated fully until you feel a click or resistance from the holder's retention mechanism. For maintenance, keep the bit clean and free of metal shavings or debris, as these can prevent the tip from seating fully into the screw head. While made from durable steel, it is susceptible to surface oxidation if left in damp environments; store in a dry tool chest or use a light coating of machine oil if storing the bit for extended periods in humid climates.
