Will these bits work on stripped fasteners or just tamper-proof ones?

Security bits are designed for tamper-proof fasteners first, but the aggressive grip they provide often works on partially stripped fasteners too. Test on a sample fastener before committing to the full job.

Does the flex extension work with a standard power drill?

The extension is designed for hand tool use with bit-compatible drivers and screwgun attachments. Check your drill chuck diameter against the bit shank before using on power tools — some cordless drills may slip with the flex extension under load.

What if a bit breaks or gets lost during the job?

The kit ships with 60 bits to cover a full range of security fastener types. Individual bit replacement is available — check with ModSupply for bulk bit refills if you're running a shop.
