What is a tapered fastener?
A taper pin is a fastener used in mechanical engineering. They are steel rods with one end having a slightly larger diameter than the other. (A 1:48 taper means that one end of a 4-foot-long bar (48 inches) will be 1 inch smaller in diameter than the other end, or a 1⁄4-inch taper over a 1-foot length.
What are the 3 main types of threaded fasteners?
There are three main types of threaded fastener; Bolts, Screws and Studs. Bolts have a head on one end (this is usually a hex head) and are threaded on the other. They are generally used in conjunction with a nut (and sometimes a washer) to hold them in place.

- Flat washers.
- Tension control bolts.
What is a threaded taper pin?
Threaded Taper Pins are round pins that the diameter uniformly increases along the length of the pin and have a thread at the large end. Metric taper pins have a 1:50 taper which means that for every 50mm in length the diameter increases by 1mm. The nominal size is the diameter of the small end on the pin.
What are the two types of mechanical fastening in manufacturing processes?
