GB/T 13829.8-2004 in English

《GB/T 13829.8-2004圆头槽销》由TC85（全国紧固件标准化技术委员会）归口，主管部门为中国机械工业联合会。
本部分规定了公称直径d1为1．4～20mm、由冷镦钢制造的、在销表面有三个互成120°纵向沟槽的圆头槽销。 扩展直径d2由沟槽每边挤出的材料形成，且d2大于d1。当槽销压入直径等于公称直径d1的钻孔时，形成局部锁紧配合。

1 Scope

This part specified the characteristics of the grooved pins with round head which have three equally spaced grooves impressed longitudinally on their exterior surface, with nominal diameter d1 from 1.4mm to 20mm inclusive.
The displaced material to each side of the grooves forming an expanded diameter, d2, which is larger than the nominal diameter d1,will cause a non-positive locking fit when these grooved pins are forced into a drilled hole equal to the nominal diameter d1 (see Chapter 4).
