    • A pin has a pilot point of uniform width throughout 360.degree. and a body containing a cross section of arcuate polygonal lobular configuration, also of uniform width but wider than the point. The pin may be driven into a circular hole in a member such that the lobes of the pin are elastically deformed in compression to enhance the grip between the pin and the member and with there being regions of stress relief on the member intermediate the lobes. The hole in the member may also be reshaped into a lobular form. The uniform body width approximates the minimum diameter of the hole in the member. Furthermore, the pin is of a range of lobulation sufficient to span a wide range of hole diameter tolerances.
    • 一个销具有360度均匀宽度的导向点和一个包含弓形多边形小叶构造的横截面的主体,其宽度均匀但宽于点。 销可以被驱动到构件中的圆形孔中,使得销的凸角在压缩中弹性变形以增强销和构件之间的夹紧,并且在该凸起上方的构件上存在应力释放区域。 构件中的孔也可以重新成形为小叶形。 均匀的身体宽度近似于构件中孔的最小直径。 此外,该销具有足以跨越宽范围的孔径公差的分叶的范围。
