Value Collection MSC67703520X Threaded Taper Pin Size 3

Product Description

The VALUE COLLECTION MSC67703520X is a Size 3 externally threaded taper pin used to secure components on shafts, flanges, and assemblies where positive locking and easy removal are required. Machined from C-12L14 free-machining steel and left uncoated, it features a 10-32 threaded end that accepts a nut to prevent the pin from backing out under vibration or load. The large end diameter measures 0.217 inches and the neck diameter is 0.144 inches, with a pin length of 0.75 inches. Maximum diameter tolerance is held to 0.0013 inches, meeting AN386 standards. Machinists, millwrights, and maintenance technicians install this type of fastener in light-duty mechanical and structural applications.

This taper pin is suited for use in mechanical assemblies across manufacturing, maintenance, and repair operations. The threaded design is preferred in applications where the pin must be retained securely or extracted without damage to the mating bore. A 0.75-inch pin length makes it appropriate for thin hubs, collars, and brackets. This pin is sold individually with a minimum order quantity of 5 units.

Installation Notes

Installation requires a correctly sized taper pin reamer to prepare the mating hole before driving the pin. Ensure the assembly is secured and free of load before insertion. A 10-32 nut should be torqued to the fastener manufacturer or assembly drawing specification. Remove the pin using a punch from the small end or by unthreading the nut and pressing out as designed.
