Value Collection MSC67706887X Threaded Taper Pin Size 8

Product Description

The VALUE COLLECTION MSC67706887X is a Size 8 threaded taper pin manufactured from 303 grade 18-8 stainless steel with a passivated finish. The pin measures 3.5 inches in length with a large end diameter of 0.49 inches and a neck diameter of 0.368 inches. The threaded end is sized 7/16-20, providing a secure mechanical connection in precision assemblies. Maximum diameter tolerance is held to 0.0013 inches, making it suitable for close-tolerance applications. The passivated stainless steel construction resists corrosion, making this pin appropriate for use in harsh or moisture-exposed environments. Machinists, millwrights, and maintenance technicians typically install this type of fastener in mechanical assemblies requiring reliable alignment and retention.

Threaded taper pins of this size are commonly used in industrial machinery, mechanical assemblies, and equipment maintenance applications where a removable but secure pin connection is required. The 7/16-20 threaded end allows a nut to be applied to prevent the pin from backing out under vibration or load. This pin is appropriate for both original equipment installation and field replacement in production and maintenance environments. It meets AN386 standards, making it compatible with aerospace-influenced and precision industrial applications where standardized fastener geometry is specified.

Key Features

• Size 8 taper pin geometry with 0.49 inch large end diameter for precision fit
• 7/16-20 threaded end accepts a standard nut to lock the pin in place
• 303 grade 18-8 stainless steel construction for corrosion resistance
• Passivated finish enhances surface corrosion resistance beyond base alloy
• Diameter tolerance of 0.0013 inches supports close-tolerance mechanical assemblies
• Meets AN386 standard for threaded taper pin geometry and dimensions

Compatibility

Designed as a standard AN386 threaded taper pin replacement for Size 8 applications requiring a 7/16-20 threaded end in stainless steel construction.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a pin driver or press. Always ensure the mating taper hole is clean, free of burrs, and properly reamed to the correct taper before driving the pin. Secure the threaded end with an appropriate nut to prevent loosening under dynamic loads. Avoid over-driving, which can distort the receiving bore or crack the pin.
