Most Suppliers Ship Parts.
We Ship Parts That Fit.
Send us your drawing. Our engineers review it within 12 hours and have a sample to you in 7 days, so you can verify the fit before committing to full production.
What We Make
If It's on Your Drawing, We Can Build It.
Share your OD, pitch, material, and application. Our engineers will handle the rest.
Auger Shafts
A shaft that’s off by 2mm isn’t a “minor defect” — it’s your crew burning an afternoon on a fix that should never exist. Every unit is CNC machined and tested for straightness before it leaves the floor
OD: 30 – 1,500 mm
Length: Up to 10 m
End Connection: Flange / Keyway / Spline / Plain
Continuous Cold-Rolled Screw Flights
Wear that shows up six months early means you’re back on the phone sourcing parts — six months early. We cold-roll every flight. The surface lasts longer. That call gets pushed out.
OD: 100 – 1,200 mm
ID (min): 28 mm
Thickness: 3 – 12 mm
Pitch: 50 – 300 mm
Sectional Screw Flights
Throwing out a whole flight because 20% of it is worn is like junking a car for a flat tire. These are modular — swap the section. Your line is back up in hours, not weeks.
OD: Up to 3,000 mm
ID (min): 25 mm
Thickness: 3 – 60 mm
Pitch: 60 – 3,000 mm
Material Options

Industries We Serve
Wrong Parts Cost You More Than the Parts Themselves.
We match material grade, tolerance, and surface treatment to your actual operating conditions, not just the dimensions on your drawing.
Agriculture & Grain
One undersized flight. 500 tons of grain sitting still.
Your drawing. Our dimensions. Fits like OEM — without the OEM price.

Grain Drying & Storage
Grain spoils by the hour. Your conveyor can't wait two months for a replacement.
2 to 4 weeks from order to delivery. Your harvest doesn't pause.

Cement & Mining
Standard flights in an abrasive line. Eaten through before you expect it.
We extend service life so you replace less and run longer.
