2 ?5 }3 N0 ^5 {: i2 }+ Z" o. vStep 1. Think about the thickness of the materials. About two-thirds of the screw should go into the second piece, but the screw should not extend through the other side.$ q6 c0 k. T9 e5 H' r
看一下两个被连接物体的厚度，螺丝2/3的长度应该拧入第二个物体，但不能穿透第二个物体。" K' b+ Z; [4 ^$ q. _, v9 _

用木螺钉，一种能负荷较大的木螺丝，用于木-铁板间的连接* m5 r( a; a6 k( }2 l
注：这里说的木螺钉是这种，六角头的，一般我们是用不到的，主要用于体积较大的木质物件和铁之间的连接。
