Precision Hardened Dowel Pins (DIN 6325 / ISO 8734)

Precision Dowel Pins Product Overview

Precision Dowel Pins (DIN 6325) are solid parallel pins ground to exact limits (usually m6 or h6 tolerances). They locate mating parts inside machine frames, gearboxes, and press molds, locking alignments without dynamic play.

Micro-Ground Precision & Hardness Features

• Conforms strictly to DIN 6325 / ISO 8734 standards.
• Case-hardened (58-62 HRC) to prevent wear and deformation.
• Ground finish ensures smooth, zero-play press fits.
• Beveled ends for easy chamfered insertion.
• High shear strength prevents structural shifting.

Toolmaking, Machinery & Automotive Alignment Uses

Our Dowel Pins components are used across multiple sectors for critical positioning assemblies:

• Aligning molds, dies, and press fixtures
• Crankshaft and cylinder head placement
• Gear transmission block alignment
• Precision mechanical instrument pivot stops
