Value Collection 70009 Precision Dowel Pin 4x12mm 50-pack

Product Description

The VALUE COLLECTION 70009 is a precision dowel pin designed for accurate alignment and location of mating components in mechanical assemblies. Machined from Grade 8 alloy steel, this pin measures 4 mm in diameter and 12 mm in overall length, with rounded ends that allow controlled insertion into reamed or ground holes. The bright finish indicates a clean, uncoated surface suitable for applications where close tolerances are required. Manufactured to DIN 6325 and ISO 8734 standards, the 70009 is well suited to tool and die work, fixture building, and precision machine assembly. Each package contains 50 pins.

Precision dowel pins of this type are used wherever repeatable, accurate part positioning is needed. Common applications include locating machine tool fixtures, aligning press tooling, registering stamping dies, and securing precision jig components. The 4 mm diameter and 12 mm length make this pin a standard choice for light-duty to medium-duty alignment tasks in both production and maintenance environments. Machinists, tool and die makers, and mechanical assembly technicians are the primary installers of this type of fastener.

Compatibility

Designed as a standard DIN 6325 and ISO 8734 precision dowel pin suitable for use in any application requiring a 4 mm diameter, 12 mm length ground pin installed into a precision-reamed or ground hole.

Installation Notes

Precision dowel pins are typically installed by machinists or tool and die makers using an arbor press or similar controlled-force equipment. The receiving hole should be finish-reamed or ground to the appropriate tolerance class specified by DIN 6325 or ISO 8734 to ensure proper fit. Never drive precision dowel pins with a hammer, as this can damage the pin, the hole, or both. Remove all chips and debris from the hole before installation to prevent galling or seizing.
