Value Collection MSC67706366X Taper Pin Size 5 Stainless

Product Description

The VALUE COLLECTION MSC67706366X is a Size 5 threaded taper pin machined from Grade 303 18-8 stainless steel with a passivated finish. The large end diameter measures 0.287 inches, and the pin body length is 4 inches. The 1/4-28 threaded end allows secure retention with a standard nut, preventing the pin from backing out under load or vibration. The passivated finish enhances corrosion resistance without adding significant dimensional buildup. This pin meets AN386 standards and is suited for mechanical assembly work in industrial, aerospace-adjacent, and trade applications where precise alignment and removable fastening are required.

Threaded taper pins of this type are used in shaft-to-hub connections, lever assemblies, linkage joints, and mechanical subassemblies where a taper fit provides accurate, repeatable alignment. Size 5 pins are common in mid-range mechanical components. The 1/4-28 threaded end is appropriate for assemblies that require the pin to be drawn tight or backed out with a nut, making installation and removal straightforward in both initial assembly and field service scenarios. Machinists, millwrights, and mechanical contractors are the primary installers.

Compatibility

Designed as a standard AN386-compliant Size 5 threaded taper pin for use in mechanical assemblies requiring a 0.287 inch large end diameter taper fit with a 1/4-28 threaded retention end.

Installation Notes

Installation is typically performed by a machinist or millwright using a properly sized reamed taper hole. Always de-energize and lock out equipment before servicing any assembly containing taper pins. The taper hole must be reamed to the correct Size 5 taper specification before driving the pin to avoid galling the stainless steel surface. Use a standard nut on the 1/4-28 thread to seat the pin fully and to facilitate removal without damaging the assembly.
