本规范涵盖由碳钢制成的管状销，其具有全长纵向槽，以允许插入孔中时弯曲。该产品通常用于提供一个具有足够弯曲度的销，在将其自身调整到孔公差后，使其紧靠已插入的孔表面。除非本文另有规定，否则尺寸和公差以英寸为单位。

This specification covers tubular-shaped pins, fabricated from carbon steel, having a full-length longitudinal slot to permit flexure when inserted into a hole.This product has been used typically to provide a pin with sufficient flexure to remain tight against the surface of a hole into which it has been inserted after adjusting itself to the hole tolerances.Unless otherwise specified herein, dimensions and tolerances are in inches.
