Value Collection MSC67702886X Size 8 Stainless Taper Pin

Product Description

The VALUE COLLECTION MSC67702886X is a Size 8 taper pin machined from 303-grade 18-8 stainless steel with a passivated finish. Taper pins are precision fasteners used to secure hubs, collars, and levers to shafts or to align mating components with repeatable, self-locking engagement. This pin measures 2.5 inches in overall length with a small end diameter of 0.44 inches and a large end diameter of 0.492 inches, conforming to ANSI/ASME B18.8.2 dimensional standards. The passivated stainless surface resists corrosion in wet or chemically active environments. Machinists, millwrights, and maintenance technicians are the primary installers of taper pins in industrial and mechanical assembly work.

This taper pin is suited for light-to-medium duty shaft and hub assemblies in industrial machinery, pump drives, conveyor systems, and general mechanical assemblies where corrosion resistance is a requirement. The 303 stainless steel grade offers good machinability alongside adequate strength for most mechanical fastening applications. It is appropriate for both original equipment manufacturing and field maintenance replacement scenarios where an ANSI/ASME B18.8.2 compliant Size 8 taper pin is specified.

Key Features

• Size 8 taper pin conforming to ANSI/ASME B18.8.2 dimensional standards
• 303-grade 18-8 stainless steel construction for corrosion resistance
• Passivated finish enhances surface oxide layer for additional corrosion protection
• Small end diameter of 0.44 inches, large end diameter of 0.492 inches
• 2.5 inches overall length with controlled diameter tolerances for precise fit
• Self-locking taper geometry provides secure, repeatable component alignment

Compatibility

Designed as an ANSI/ASME B18.8.2 compliant Size 8 taper pin for use in any hub, collar, or shaft assembly that specifies a Size 8 taper pin in 303 stainless steel.

Installation Notes

Taper pins are typically installed by machinists or maintenance technicians using a tapered reamer to prepare the mating hole and a pin driver or hammer to seat the pin. Ensure mating components are properly aligned and clamped before driving the pin. Remove all rotational energy from the assembly and de-energize associated machinery before installation or removal. Do not substitute taper pin sizes, as dimensional differences will result in improper seating and potential joint failure.
