DIN 1 taper pins are solid dowel pins with a large diameter at one end and a gradually decreasing diameter at the other end. Taper pins rely on their taper to self-lock in the hole, holding two parts tightly together. The taper of standard imperial taper pins is 1:48, while the taper of metric DIN 1 taper pins is 1:50 (a 1 mm change in diameter per 50 mm length). Imperial taper pins use the larger end diameter as the reference, while metric DIN 1 taper pins use the smaller end diameter as the baseline.
