Value Collection MSC67700484X Taper Pin Size 3/0 Stainless

Product Description

The VALUE COLLECTION MSC67700484X is a Size 3/0 taper pin machined from Grade 303 18-8 stainless steel with a passivated finish. It measures 1 inch in overall length, with a small end diameter of 0.1042 inches and a large end diameter of 0.125 inches. The tapered geometry creates a self-locking fit when driven into a matching reamed hole, providing precise and repeatable component alignment. Diameter tolerances are held to -0.0007 inches on the minimum and +0.0013 inches on the maximum, meeting ANSI/ASME B18.8.2 standards. Machinists, millwrights, and mechanical assembly technicians install taper pins in production and maintenance environments.

Taper pins are used to locate and lock components such as hubs, collars, gears, and levers onto shafts in both light industrial and precision mechanical assemblies. The passivated stainless steel construction makes this pin suitable for applications with exposure to moisture, mild chemicals, or sanitary requirements where corrosion resistance is a priority. This size is appropriate for small-bore shaft assemblies and precision instrument work where a compact, reliable fastening method is required. Sold individually with a minimum order quantity of 10 pieces.

Compatibility

Designed for use in standard Size 3/0 taper-reamed holes per ANSI/ASME B18.8.2 in light industrial shaft and hub assemblies requiring stainless steel fasteners.

Installation Notes

Taper pins are installed by machinists or mechanical technicians using a taper pin reamer to prepare a properly sized hole before driving the pin. Always ensure the mating hole is reamed to the correct taper before insertion to prevent galling or incomplete seating. Drive the pin with a hammer and appropriate pin punch; do not force an oversized pin into an undersized hole. Depowering or de-energizing rotating equipment before installation is required per standard lockout/tagout procedures.
