Flat Head Jack Screw Rods

To match every operating environment, we offer six surface treatment options: Black Oxide for economical indoor corrosion resistance, Zinc plating for moderate-environment protection, Phosphate for lubrication-compatible assemblies, PTFE coating for low-friction and chemical-resistant performance, Dacro for outstanding salt-spray durability, and Yellow Galvanized for heavy-duty outdoor conditions.

Paired with a broad material selection — including 35K, 45K, 4141, 4340, 4145, 1045, 40Cr, 45#, 35CrMo, and SS316 stainless steel — every rod can be precisely configured to meet your load, temperature, and corrosion requirements.

Quality is built in from the start. 
All products are manufactured in strict compliance with internationally recognized standards including DIN 975, DIN 976, GB/T 9125, ASME 18.3131, NFE25-136, and HG/T 20634 — ensuring seamless integration into global OEM supply chains with consistent, batch-to-batch reliability.
We also understand that standard specifications don't always fit real-world production needs. 
That's why full OEM and ODM customization is available, covering custom thread forms, lengths, diameters, surface finishes, and packaging — for both prototype runs and high-volume orders.
