Stift - Pin

A pin is an elongated fastener of cylindrical or conical shape made of carbon steel, designed for rigid connection of parts.

A metal rod is inserted into a hole running through both parts and prevents them from shifting relative to each other.

Installation

The parts to be joined are positioned according to the drawing requirements and fixed with a universal or special clamp. The following operations are then performed.

1. Marking and drilling the pilot hole according to the drawing.
2. Finishing the hole with a reamer.
3. Driving in a plain pin or screwing in a threaded pin.

Selection

By cross-section shape, cylindrical pins can be plain, split, or grooved. The taper pin with a 1:50 taper is considered more reliable: it provides precise centering and is easier to remove when needed. Taper fasteners are divided into plain and threaded: the former is used for through holes, the latter for blind holes.
