Abstract

TORNILLO PRISIONERO COMPLETAMENTE RETRACTIL. EL TORNILLO PRESENTA PERFIL BAJO Y TIENE CARACTERISTICAS DE RETENCION POR ENGATILLADO QUE PERMITEN LA INSTALACION DEL DISPOSITIVO EN UN ORIFICIO DE UN PANEL DE FORMA MANUAL, SIN NECESIDAD DE HERRAMIENTAS SEPARADAS. EL TORNILLO PRISIONERO COMPLETAMENTE RETRACTIL TIENE UN TORNILLO, UN BOTON CON UN REBAJE PARA DESTORNILLADOR POR SU PARTE ALTA, UN CASQUILLO CILINDRICO CON UN MECANISMO DE ENGATILLADO ACOPLADO AL MISMO Y UN RESORTE QUE PROVOCA QUE EL TORNILLO SE RETRAIGA DENTRO DEL CASQUILLO CUANDO EL TORNILLO NO ESTA ACOPLADO.
