• Accurate Shoulder Dimensions: Shoulder diameter and length affect how a pin locates and supports mating components. We pay particular attention to these features when reviewing your drawing.
• Controlled Mechanical Fit: Critical diameters, flange dimensions, and end features can be machined to specified tolerances to help reduce assembly issues.
• 40Cr Alloy Steel: The specified material and hardness provide a practical option for tooling and mechanical components that require strength and wear resistance.
• Custom Manufacturing: Standard dimensions are not required. We can manufacture pins to your specified diameter, overall length, shoulder geometry, and tolerance requirements.
• Drawing-Based Production: We review the material, critical dimensions, quantity, and finishing requirements before confirming the manufacturing plan.

An engineering note: 40Cr is an alloy steel, not stainless steel. If your pins will operate in a humid or corrosive environment, tell us the working conditions so we can assess suitable protective finishes or alternative materials.
