Value Collection 40020 Precision Dowel Pin 6x25mm Ss Grade 303

Product Description

The VALUE COLLECTION 40020 is a precision dowel pin machined from Grade 303 stainless steel, designed for accurate alignment and positioning in mechanical assemblies. Measuring 6 mm in diameter and 25 mm in overall length, this pin holds tight diameter tolerances of 0.0000 to -0.0220 mm, making it suitable for close-tolerance fit applications. One end is beveled for easy insertion and the opposite end is rounded, a configuration that aids driven installation and reduces the risk of burring the bore. Machinists, toolmakers, and maintenance technicians use precision dowel pins to locate fixtures, jigs, dies, and mating machine components with repeatable accuracy.

This dowel pin is suited for light to medium-duty alignment tasks in manufacturing, fabrication, and maintenance environments. The Grade 303 stainless steel construction provides corrosion resistance and strength, making it an appropriate choice for applications exposed to moderate moisture, coolants, or cleaning agents. The pin is packaged in a quantity of 10, covering multiple installation points or providing spares for ongoing service work. It fits standard 6 mm reamed or precision-bored holes commonly found in tooling plates, machine frames, and assembly fixtures across a range of industrial and trade settings.

Key Features

• Grade 303 stainless steel construction for corrosion resistance and machinability
• 6 mm diameter with tight tolerance of 0.0000 to -0.0220 mm for close-fit alignment
• 25 mm overall length suits standard tooling and fixture applications
• One beveled end and one rounded end for controlled, damage-free installation
• Packaged in a quantity of 10 for multi-point alignment jobs or service stock

Compatibility

Designed as a standard precision dowel pin for use in any application requiring a 6 mm close-tolerance locating pin in a reamed or precision-bored hole.

Installation Notes

Precision dowel pins are typically installed by machinists or maintenance technicians using a pin press or soft-faced mallet. The receiving bore should be reamed to the appropriate tolerance class to achieve the intended fit. Always clean and deburr the bore before installation. Do not exceed the rated engagement depth, and avoid driving pins into undersized holes, which can crack or deform the bore.
