A typical door frame includes a gap between the 2x4 structural framing and the flat door jamb on which hinges and door latches are installed. This gap occurs when carpenters square the jamb within the rough door opening using wooden wedges. This gap means plate screws have a limited amount of material to grab, because screws that come with hinge and latch hardware are often less than 1" long.
In addition, many jambs are made of soft pine or MDF and typical mounting screws have relative shallow threads. All this results in screws which tend to strip out and doors which are easily opened with a forceful kick.
ZZem Screws offer a long, coarse threaded body which extends across any framing gaps and screw securely into the structural framing of the door. The screws which hold the hinge or latch plate are threaded into the metal of the ZZem Screw, providing superior holding power and resistance to forceful entry.
Alarm systems are great, however they typically only work after intruders have actually gained entry into your house. In fact, most burglars don’t care if you have a porch light or security camera! With ZZem Screw, you have the power of screws in hinges and latches deep into your door's framing, thus reinforcing any weak points on your doors. Rather than alerting you that an intruder is in your house, ZZem Screw will keep the burglars out entirely.
