Clevis Pins Without Head

To make the clevis pins without head work better, they do special surface treatments. Black oxide coatings give some rust protection but don’t change the size much, which is good for precision. Electropolished ones get really smooth (Ra 0.2µm), so they’re used in cleanrooms where everything has to be super clean. For places with a lot of wear, they spray on tungsten carbide with HVOF,this makes the surface super hard (1,500 Vickers). Electroless nickel plating adds a uniform layer (15-25µm) that’s slippery on its own. In food processing, we use FDA-approved DLC coatings that are hygienic and have almost no friction. We can etch serial numbers with lasers for tracking in regulated industries without weakening the pin. These treatments make the pin last three times longer in rough environments and let you customize it for specific needs.

Quality Testing

Every clevis pins without head goes through strict testing: check Rockwell hardness across the surface, do salt spray tests (following ASTM B117 to see how well it resists rust), and use a CMM machine to verify dimensions. Each batch can be traced by laser-marked heat numbers that match the mill certificates,so you can track where the material came from.

For critical dimensions,Xiaoguo® use statistical process control to keep CpK values above 1.67 (which means the manufacturing is very consistent). Ultrasonic testing is done to find any internal flaws bigger than 0.3mm. Fatigue testing pushes the pin to 120% of its rated capacity for 10 million load cycles to see how it holds up under stress.

There are certifications too: AS9100D for aerospace use and ISO 13485 for medical devices. This multi-step quality control process makes sure the headless pin meets military specs (MIL-SPEC) and German industrial standards (DIN) every time, so it’s reliable in important applications worldwide.

MOQ

Q: What is the minimum order quantity (MOQ) for clevis pins without head, and what’s the typical lead time for bulk orders?

A: The minimum order quantities (MOQs) for headless clevis pins differ by supplier, but standard sizes often start at 500-1,000 units. Custom orders might need higher MOQs because changing the tooling for specific designs takes extra work. For in-stock items, lead times are usually 2-4 weeks, while custom batches take 6-8 weeks. If you need them faster for urgent projects, many suppliers offer expedited production. When ordering, make sure the supplier uses ISO-certified packaging to protect the pins during shipping,especially important for international orders to your area.
