Value Collection MSC67706085X Size 4 Threaded Taper Pin

Product Description

The VALUE COLLECTION MSC67706085X is a Size 4 threaded taper pin machined from 303 grade 18-8 stainless steel with a passivated finish. The pin features a 1/4-28 threaded end, a large end diameter of 0.248 inches, a neck diameter of 0.198 inches, and a pin length of 2.25 inches. Passivation removes surface iron and enhances corrosion resistance without altering dimensional tolerances. This fastener is used by machinists, maintenance technicians, and assemblers working with precision mechanical assemblies where a reliable, corrosion-resistant locking pin is required.

Threaded taper pins are used in applications where the pin must be positively retained and easily removed during maintenance. The 1/4-28 threaded end accepts a standard nut to draw the pin fully into a tapered hole and lock mating components such as hubs, collars, levers, and shafts. This pin conforms to AN386 standards, making it suitable for use in aerospace, industrial, and general mechanical assemblies that require dimensional traceability to a recognized specification.

Key Features

• Size 4 taper pin with 0.248 inch large end diameter and 0.198 inch neck diameter
• 1/4-28 threaded end for positive retention with a standard nut
• 303 grade 18-8 stainless steel construction for corrosion resistance
• Passivated finish removes surface contaminants and improves oxidation resistance
• Conforms to AN386 standard for dimensional consistency
• Maximum diameter tolerance of 0.0013 inches for precise fit

Compatibility

Designed as an AN386-compliant Size 4 threaded taper pin suitable for standard tapered holes in hubs, collars, and mechanical assemblies requiring a 1/4-28 threaded retention fastener.

Installation Notes

Threaded taper pins are installed by machinists or maintenance technicians using a standard reamer to prepare a properly sized tapered hole before driving or drawing the pin in place. Ensure mating components are de-energized, depressurized, or otherwise secured before disassembly or pin removal. A nut threaded onto the 1/4-28 end is used to seat and retain the pin; use appropriate wrenches and avoid over-driving to prevent bore damage. Follow applicable facility maintenance procedures and relevant industry standards when installing fasteners in load-bearing or safety-critical assemblies.
