Pan Head Machine Bolt
Designed for heavy-duty assembly applications where a flat clamping surface and a robust head profile are required, our pan head machine bolt offers unmatched reliable performance. The broad, flat underside of the pan head acts like an integrated washer, distributing the clamping force evenly across the surface of the workpiece to prevent material deformation.

The broad, flat underside of the pan head acts like an integrated washer, distributing the clamping force evenly across the surface of the workpiece to prevent material deformation. Over our 14-year manufacturing journey, we have optimized the thread profile of the pan head machine bolt to guarantee clean, smooth engagement with female threads or tapped holes in metals and plastics. Our factory has supplied these bolts to public companies in the automotive parts, heavy machinery, and electrical enclosure industries, earning long-term partnerships due to our extremely low defect rates and consistent material tensile strength.


When you partner with our factory for your pan head machine bolt supply, you gain direct access to wholesale pricing and specialized OEM/ODM manufacturing. We operate a highly efficient dual-facility model: our manufacturing plant in Jiangxi Shangrao ensures low production costs, while our Hangzhou office handles sales, warehousing, and swift overseas logistics. We back our products with a comprehensive 1-year warranty and a clear policy to replace or refund any goods damaged during shipping. We understand the tight schedules of modern distributors, which is why we guarantee a standard production lead time of 15 to 20 days and offer shorter turnaround times for repeat orders.
