Value Collection MSC67706648X Taper Pin Size 7 Ss

Product Description

The VALUE COLLECTION MSC67706648X is a Size 7 externally threaded taper pin manufactured from Grade 303 18-8 stainless steel with a passivated finish. The pin measures 2.5 inches in length with a large-end diameter of 0.407 inches and a maximum diameter tolerance of 0.0013 inches. The 3/8-24 threaded end allows secure nut retention after installation, preventing the pin from backing out under vibration or load. Passivation removes surface iron contaminants and enhances the natural corrosion resistance of the stainless steel base material. This fastener is suited for mechanical assemblies where corrosion resistance and precise alignment are required.

Threaded taper pins are used in mechanical and structural assemblies to lock hubs, collars, levers, and other components to shafts. The taper geometry provides self-locking engagement when driven into a reamed tapered hole, and the threaded end allows controlled extraction using a nut and washer without damaging the assembly. This pin is appropriate for industrial, marine, and maintenance applications where stainless steel is specified for environmental or chemical resistance.

Key Features

• Grade 303 18-8 stainless steel construction for corrosion resistance
• Passivated finish removes surface contaminants and improves oxide layer integrity
• 3/8-24 threaded end for nut-assisted retention and controlled extraction
• Large-end diameter of 0.407 inches with a maximum tolerance of 0.0013 inches
• Meets AN386 standard
• Size 7 taper pin designation for use in standard reamed taper holes

Compatibility

Designed as a standard AN386-compliant Size 7 threaded taper pin for use in any application requiring a 0.407-inch large-end diameter reamed tapered hole with a 3/8-24 threaded fastener.

Installation Notes

Installation requires a properly reamed tapered hole sized to match the Size 7 taper specification. Power down and de-energize any machinery before installing or removing taper pins in rotating or actuating assemblies. Drive the pin to full seat using a pin punch and hammer, then thread a nut and washer onto the threaded end to secure the pin in position. For removal, apply the nut to the threaded end and back the pin out without hammering against the small end, which can deform the taper.
