    • The invention relates to a hand-held screw (10) adapted to be easily manipulated by a user during insertion into an intended screw hole (100). The screw comprises an elongated stem (11) having a threaded and non-threaded portion (20, 30). A breakaway (25) releasably couples the non-threaded portion (30) to the distal end (C) of the threaded portion (20). The non-threaded portion has a diameter (W 3 ) smaller than a diameter (W 2 ) of the threaded portion to facilitate its insertion into a screw hole (100). The length (L 2 -L 1 ) of the non-threaded portion (30) is greater than the length (L 1 ) of the threaded portion (20) thereby facilitating grasping and manipulation thereof by a user on entry of the threaded first portion into a screw hole (100). The breakaway (25) is removable on complete insertion of the screw into the screw hole (100) by braking or cleaving.
    • 本发明涉及一种手持式螺丝(10),其适于在插入到预期的螺纹孔(100)期间由使用者容易地操纵。 螺杆包括具有螺纹和非螺纹部分(20,30)的细长杆(11)。 分离式(25)将非螺纹部分(30)可释放地联接到螺纹部分(20)的远端(C)。 非螺纹部分的直径(W 3)小于螺纹部分的直径(W 2),以便于其插入螺钉孔(100)。 无螺纹部分(30)的长度(L 2 -L 1)大于螺纹部分(20)的长度(L 1),从而便于使用者在螺纹第一部分进入时的抓握和操纵 进入螺孔(100)。 通过制动或切割将螺钉完全插入螺钉孔(100)中,分离器(25)是可拆卸的。
