Metric Blue UST204920 Pull Dowel Pin 8x20mm Alloy Steel

Product Description

The METRIC BLUE UST204920 is a pull dowel pin manufactured from alloy steel to DIN 7979D standards. It measures 8 mm in diameter and 20 mm in overall length, with a beveled end geometry that facilitates accurate alignment and smooth insertion during assembly. Pull dowel pins of this type are used to precisely locate and align machine components, fixtures, and tooling plates. Machinists, tool and die makers, and maintenance technicians install these pins in controlled-tolerance bores where repeatable component positioning is required. The DIN 7979D standard governs the dimensional and tolerance requirements for this pin style.

This pull dowel pin is suited for use in industrial machinery, jigs, fixtures, molds, and precision assembly applications where exact part alignment must be maintained across repeated disassembly and reassembly cycles. The beveled end eases entry into the bore, reducing the risk of bore damage during installation. Applicable in both light and heavy manufacturing environments, this pin is a standard hardware item stocked and used by machine shops, maintenance departments, and production facilities working to metric fastener standards.

Key Features

• Conforms to DIN 7979D standard for pull dowel pin geometry and tolerances
• Alloy steel construction for strength and wear resistance in precision bore applications
• Beveled end type for guided, damage-free installation into close-tolerance bores
• 8 mm diameter x 20 mm overall length for common metric tooling and fixture applications
• Consistent dimensional accuracy supports repeatable component alignment

Compatibility

Designed as an OEM-style metric pull dowel pin for use in precision fixtures, jigs, molds, and machine assemblies requiring DIN 7979D-compliant locating hardware.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or appropriate driving tool sized for the bore. Always ensure the mating bore is clean, dimensionally correct, and free of burrs before installation. De-energize and lock out any machinery before installing or removing locating pins from live equipment. Do not force the pin into an undersized bore, as this may damage the bore geometry or compromise alignment accuracy.
