Value Collection MSC67703207X Taper Pin Size 9 4in Ss

Product Description

The VALUE COLLECTION MSC67703207X is a size 9 taper pin machined from 303 stainless steel with a passivated finish. It features a small end diameter of 0.5078 inches and a large end diameter of 0.591 inches, with an overall length of 4 inches. The tapered profile creates a self-locking fit when driven into a matching tapered hole, making it suitable for securing hubs, collars, and machine components against rotation or axial movement. The passivated finish improves corrosion resistance without altering dimensional tolerances. This pin is manufactured to ANSI/ASME B18.8.2 standards, making it a reliable choice for precision mechanical assemblies in industrial, HVAC, and equipment maintenance applications.

This taper pin is intended for use in mechanical assemblies where a removable, self-locking fastener is required to align or lock mating parts on a shaft or in a housing. Typical applications include machine tool components, motor shafts, gear hubs, and structural alignment in commercial and industrial equipment. The 303 stainless steel grade, also classified as 18-8, provides good machinability and corrosion resistance, making it well suited for environments with moisture exposure or mild chemical contact. Machinists, millwrights, and maintenance technicians are the primary installers of this type of pin.

Compatibility

Designed as an ANSI/ASME B18.8.2 standard size 9 taper pin for use in any application requiring a matching tapered reamed hole of the appropriate diameter range.

Installation Notes

Taper pins are typically installed by machinists or millwrights using a pin punch and hammer or an arbor press. Before installation, ensure the mating tapered hole is properly reamed to the correct taper angle and diameter to achieve full contact. Always de-energize and lock out any equipment before driving or removing a taper pin. Removal is accomplished by driving the pin out from the small end using an appropriately sized pin punch.
