JTXTOOLS Screw-Killer – Micro-Screw Extractor
JTXTOOLS Screw-Killer is a precision kit for the emergency removal of damaged screws in phones and delicate electronics. Two tips – for drilling and for unscrewing – allow you to quickly regain access to your device without the risk of enlarging the hole or damaging the frame.
The special reverse helical geometry works like a gripping wrench: when turned counterclockwise, the tip gently "bites" into the screw head and securely loosens it. The ultra-thin design is ideal for screws near the charging port and in tight spaces (e.g., iPhone, Samsung, Huawei). The tips work with a handheld pin-vise holder or a mini drill/pen-grinder.

Precision rescue tool for phones and delicate electronics. A set of two tips allows you to drill the damaged screw and then unscrew it safely – without enlarging the hole and risking damaging the housing.

Extractor for damaged screws – a professional drill bit for them removal.
JTXTOOLS Screw-Killer are ultra-thin, precision tips designed for working in tight spaces – ideal for micro-screws near the charging port or in smartphone bezels (including iPhone, Samsung, Huawei). The special left-handed slot geometry works like a delicate "key" in reverse: when turned counterclockwise, the tip simultaneously grips and loosens the stripped screw, helping you remove it without damaging the existing hole.

Quick instructions for use
- Drilling: Use the thin drill bit from the set and make a short, controlled drill hole in the stripped screw.
- Removing: Change the tip to the screw extractor. Turn counterclockwise, slightly increasing pressure until the screw starts to come out.
- Caution: Work at low speed and with good tool support – this protects the charging port and device frame.
