Value Collection MSC67706689X Taper Pin Size 7 Stainless Steel

Product Description

The VALUE COLLECTION MSC67706689X is a Size 7 threaded taper pin machined from 303 grade 18-8 stainless steel with a passivated finish. The pin measures 3 inches in length with a large-end diameter of 0.407 inches and a neck diameter of 0.315 inches. The 3/8-24 threaded end allows for positive extraction using a standard nut and bolt puller, making removal clean and repeatable. Passivation improves corrosion resistance by removing free iron from the surface. Maximum diameter tolerance is held to 0.0013 inches, supporting precise interference fits in critical assemblies. This pin is installed by machinists, millwrights, and maintenance technicians working on shaft, hub, and mechanical assembly applications.

Threaded taper pins are used in mechanical assemblies where positive location, load transfer, and reliable extractability are required. Typical applications include securing hubs to shafts, aligning mating components, and providing shear-pin functionality in rotating or reciprocating machinery. The 303 stainless steel construction makes this pin suitable for environments with exposure to moisture, mild chemicals, or food-grade wash-down conditions. The passivated finish extends service life in corrosive service conditions. This pin meets AN386 standards, making it appropriate for aerospace-adjacent, industrial, and OEM equipment repair applications.

Key Features

• 3/8-24 threaded end allows controlled extraction without damage to the mating bore
• 303 grade 18-8 stainless steel provides strong corrosion resistance in wet or chemically exposed environments
• Passivated finish removes surface iron contamination for enhanced oxidation resistance
• Maximum diameter tolerance of 0.0013 inches supports tight, repeatable interference fits
• Meets AN386 standard for dimensional and material consistency
• Size 7 taper with 0.407-inch large-end diameter fits standard taper-reamed bores

Compatibility

Designed as a standard AN386-compliant Size 7 threaded taper pin for use in taper-reamed bores in industrial machinery, shaft-hub assemblies, and OEM equipment requiring a 3/8-24 threaded extraction interface.

Installation Notes

Installation should be performed by qualified machinists or maintenance technicians using a properly reamed taper bore matched to Size 7 specifications. Drive the pin from the small end using a pin driver or press; never use impact tools that may crack or deform the stainless material. Before installation, ensure the mating bore is clean and free of burrs. To remove, thread a 3/8-24 nut onto the threaded end and use a slide hammer or puller to draw the pin out without bore damage.
