Flat Head Machine Screw
Designed for applications requiring a completely flush, flat surface after installation, our flat head machine screw combines high-strength fastening with exceptional aesthetic appeal. Achieving the perfect countersunk angle and head concentricity is crucial for a flat head machine screw, as any minor dimensional defect will cause the head to protrude and disrupt the assembly.

Achieving the perfect countersunk angle and head concentricity is crucial for a flat head machine screw, as any minor dimensional defect will cause the head to protrude and disrupt the assembly. Over our 14-year history of specialized fastener manufacturing, we have refined our high-speed cold heading processes to ensure that every flat head machine screw we produce meets global specifications such as DIN 965 and ISO 2009. We work closely with our customers from the initial product design stage, allowing us to supply these precision fasteners to leading public companies in the consumer electronics, smart home, and automotive trim industries. With our daily production capacity exceeding 1 million units, we have the manufacturing muscle to support your largest bulk orders with highly consistent thread accuracy and drive depth.


Sourcing your flat head machine screw directly from our source factory guarantees that you bypass trading company markups while gaining full access to custom engineering support. We control the entire manufacturing process starting with rigorous raw material incoming checks at our 2,000 square meter facility in Shangrao, Jiangxi, down to final quality spot checks at our sales and logistics center in Hangzhou. By separating our manufacturing and sales divisions, we have successfully optimized our lead times, delivering standard batches in 15 to 20 days and custom items in 30 days. We fully accept third-party inspections from major firms like SGS or TÜV because we are confident in our strict mold maintenance and final batch testing.
