Perfect Fit for Custom Machinery

We needed non-standard nuts for a retrofit project. The CNC machining was precise and the threads matched our custom bolts perfectly.

Great Quality Carbon Steel

The material hardness is consistent across the batch. We tested several samples and they met our torque specifications without stripping.

Exact Specs Met

Hard to find vendors who will do small runs of non-standard cylindrical nuts. These worked flawlessly in our prototype setup.

Reliable Supplier for Industrial Parts

Ordered 5000 units for our assembly line. The cold-forged options were strong and the surface treatment prevented rust during storage.

Good Value for Bulk Orders

Quality is solid for the price point. Shipping took a bit longer than expected but the product itself is exactly as described.

5 FAQ

Q: Do you provide material certification with the shipment?

A: Yes, all batches come with a Mill Test Certificate (MTC) verifying the carbon steel grade and hardness treatment.

Q: How are the nuts packaged to prevent damage during transit?

A: They are packed in sealed plastic bags within reinforced export cartons, secured on wooden pallets for bulk orders.

Q: What is the maximum diameter you can forge?

A: For cold forging, we handle up to 30mm. For larger diameters, we recommend CNC machining which can accommodate up to 100mm.

Q: Can you manufacture left-hand threads for these nuts?

A: Yes, we can produce left-hand threads via CNC machining. Please specify the thread direction in your custom order requirements.

Q: Is stainless steel an option for this product?

A: This listing is for carbon steel, but we do offer stainless steel variants. Please contact us directly for a custom quote on SS materials.
