Value Collection MSC67701680X Taper Pin Size 4 Stainless

Product Description

The VALUE COLLECTION MSC67701680X is a Size 4 taper pin machined from 303 grade 18-8 stainless steel with a passivated finish for corrosion resistance. It measures 1 inch overall length with a small end diameter of 0.2292 inches and a large end diameter of 0.25 inches. Taper pins are used to secure hubs, collars, and mechanical components to shafts, providing a precise, self-locking fit that resists rotational slippage. Machinists, millwrights, and industrial maintenance technicians install these fasteners in light-to-medium duty assemblies where corrosion resistance and dimensional accuracy are required.

This taper pin is suited for use in mechanical assemblies across industrial, commercial, and trade applications where stainless steel is specified for wet, chemical, or sanitary environments. The passivated surface treatment enhances the natural oxide layer of the stainless steel, extending service life in corrosive conditions. Typical applications include shaft-to-hub connections in pumps, valves, and rotating equipment found in HVAC, plumbing, and pool system machinery. Minimum order quantity is 5 pieces; each package contains 1 pin.

Key Features

• 303 grade 18-8 stainless steel construction for corrosion resistance
• Passivated finish enhances oxide layer for extended service life in wet or chemical environments
• Small end diameter of 0.2292 inches with minimum diameter tolerance of -0.0007 inches and maximum of 0.0013 inches
• 1 inch overall length suitable for light-to-medium duty shaft and hub assemblies

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 4 taper pin for use in mechanical assemblies requiring a self-locking taper fit between shaft and hub components.

Installation Notes

Taper pins are driven into a reamed taper hole using a hammer and pin punch; the hole must be reamed to the correct taper before installation. De-energize and lock out all rotating equipment before removing or installing taper pins. Use a proper taper pin reamer sized for Size 4 to ensure full contact along the pin length. Never force an oversized pin into an undersized hole, as this can split the hub or damage the shaft.
