6. Installation & Usage Guidelines

1. Select the correct size and shaft type according to the mounting hole or locking mechanism.

2. Ensure the housing and mounting surface are flat and clean to allow full engagement of the shaft.

3. Use matching stainless steel fasteners to avoid galvanic corrosion.

4. When used in marine environments, apply a suitable anti-seize or protective lubricant on contact surfaces to extend life.

5. Regularly inspect the pin shaft for wear or corrosion, especially in high-stress applications.

7. FAQ – Common Questions

Q1: Why choose 316 stainless steel instead of 304 for this pin shaft?
A1: 316 stainless steel contains molybdenum, which enhances corrosion resistance especially in chloride or salt-spray environments. For marine or outdoor applications, 316 is significantly more durable.

Q2: Can I request custom sizes or finishes?
A2: Yes. We accept custom dimensions, thread types, and finishes (mirror polish, powder coated, etc.). Please contact us with your drawing or specification.

Q3: What is the typical load capacity of this pin shaft?
A3: Load capacity depends on installation conditions, housing materials and mounting method. Please contact us with your specific application for a load assessment.

Q4: Will the stainless steel pin shaft rust over time?
A4: When correctly installed using stainless fasteners and maintained, 316 stainless steel will resist rust and corrosion for long-term use even in harsh environments.

8. Packaging, Delivery & MOQ

• Minimum Order Quantity (MOQ): 100 pcs (stock quantities may allow smaller orders).
