The taper per foot of a tapered dowel pin is 1/4" per foot. Tapered dowel pins are commonly used in applications requiring precise alignment and easy assembly. The tapering design allows these pins to fit snugly into pre-drilled holes, ensuring that they provide a secure connection while aiding in the alignment of components.

A taper of 1/4" per foot means that for every foot of length along the dowel pin, the diameter decreases by 1/4 inch. This gradual reduction enhances the ease of insertion and helps accommodate manufacturing tolerances. The specific measurement of 1/4" enables standardized fitting in various applications, making it a common choice in mechanical assembly where dowel pins are utilized.

Understanding taper measurements is crucial in millwrighting, as it directly impacts the precision and functionality of the assembly. Being aware of these specifications aids technicians in selecting the appropriate fasteners for their tasks, ensuring reliability and efficiency in their work.
