ENGINEER DBZ-340 is an ultra-short extractor bit for removing screws with a damaged 4.0 mm hex socket. Its specially designed tip bites firmly into the rounded socket and allows the screw to be removed without hammering, by applying pressure and turning in the loosening direction.
At only 18 mm overall length, DBZ-340 is designed for confined spaces. Its standard 6.35 mm hex shank fits compatible tools and accessories; ENGINEER recommends DR-27 for restricted spaces and DR-26 or DR-28 for difficult-to-reach areas.
DBZ-340 is sized for screws with a 4.0 mm across-flats hex socket. The 4 mm value refers to the screw socket, not the bit shank.
The newly designed tip bites into the damaged hex socket and allows removal by pressing and turning without a hammering operation.
Its 18 mm overall length provides access where a conventional longer extractor or bit is difficult to use.
It can be used with the DR-27 mini ratchet and attached to DR-26 or DR-28 bit holders/adapters for difficult-to-reach areas.
For screws whose 4 mm hex socket has been rounded or damaged and can no longer be driven normally with an Allen key.
The slim tip design also allows use on compatible hex socket set screws.
ENGINEER lists field repair, automotive, motorcycle, bicycle maintenance and DIY work, particularly in confined spaces.
DBZ-340 is intended for lightly damaged screws. Press the extractor firmly into the socket and turn in the loosening direction.
