Hardened parallel pins with internal thread, known as extractable or tapped dowel pins: a dowel pin with a tapped hole in one end, hardened unlike ISO 8733. A screw or a pin extractor in the tapped hole of one end pulls the pin out. The pin is a ground cylinder toleranced m6 with a surface finish of Ra 0,8 micrometres. The tapped hole has a 6H metric coarse thread with a counterbore and a 120 degree countersink at its mouth, and a slight flat or small groove along the pin may vent the trapped air. The two types share one dimension table and differ only at the plain end, which has a 15 degree lead c: type A has a crowned end with a radius equal to the diameter and is made of through hardened steel, 550 HV30 to 650 HV30, or of martensitic stainless steel grade C1, hardened and tempered to 460 HV30 to 560 HV30; type B has a flat end and is made of case hardened steel with a surface hardness of 600 HV1 to 700 HV1. Covers nominal diameters from 6 to 50 mm with threads M4 to M24 and lengths from 16 to 200 mm.
