Value Collection A997859 Precision Dowel Pin 8x50mm Ss 303

Product Description

The VALUE COLLECTION A997859 is a precision dowel pin manufactured from Grade 303 stainless steel. It measures 8 millimeters in diameter and 50 millimeters in overall length, with a diameter tolerance of 0.0060 to 0.0150 millimeters for close-tolerance alignment applications. The pin features one beveled end and one rounded end and is supplied in an unhardened condition, making it suitable for applications where precise component alignment is required without hardened-surface contact. Machinists, tool and die technicians, and maintenance professionals use precision dowel pins to locate and align mating components in fixtures, jigs, dies, and assemblies.

This pin is used in precision machining and fabrication environments where consistent, repeatable component alignment is critical. The stainless steel construction provides corrosion resistance, making it appropriate for use in wet environments, food-adjacent equipment, or anywhere mild chemical exposure is present. The mixed end geometry — one beveled, one rounded — assists with guided insertion into reamed or close-tolerance bored holes during assembly and disassembly operations. This item is sold in a package quantity of 10.

Key Features

• 50 mm overall length suitable for standard fixture and die alignment applications
• One beveled end and one rounded end for guided, repeatable insertion
• Unhardened condition compatible with soft-metal and standard-steel mating bores
• Sold in a package of 10 pins

Compatibility

Designed as a precision alignment component for use in fixtures, jigs, dies, and mechanical assemblies requiring close-tolerance 8 mm diameter dowel pin fitment.

Installation Notes

Precision dowel pins are typically installed by machinists or maintenance technicians using a press, mallet with a soft-face drift, or an arbor press — avoid striking the pin directly with a steel hammer to prevent deformation. The receiving bore should be reamed to the appropriate close tolerance before installation. Always clean and deburr the bore before inserting the pin. Remove any residual chips or contaminants that could affect alignment accuracy.
