Tungsten Carbide Threaded Riveting Mandrel K10-K30 Grade 4000-6000 MPa
This high-strength tungsten carbide threaded riveting mandrel is a professional tool specifically designed for the automated riveting of threaded fasteners (e.g., screws, bolts, studs). Manufactured from premium tungsten carbide material, its core feature is the high-precision, high-strength internal threads machined into the ultra-hard riveting head. This design allows it to be perfectly screwed into the workpiece threads, providing unparalleled positioning accuracy and torsional strength during the riveting process. It completely solves common industry problems such as screw rotation, thread damage, and eccentric riveting, making it the ideal choice for achieving high-quality threaded riveting.
| Feature | Our WC Threaded Mandrel | Standard Steel Threaded Tool | Value for You |
|---|---|---|---|
| Wear Resistance & Lifespan | Extremely Long. WC hardness ≥ HRA 90, threads are highly wear-resistant. | Very Short. Steel threads wear rapidly during high-speed riveting, causing thread form distortion. | 100x longer life, drastically reduces changeover frequency and tooling costs, minimizes downtime. |
| Thread Accuracy Retention | Excellent. Maintains thread form and dimensional accuracy long-term, ensuring consistent riveting. | Poor. Threads are prone to wear, deformation, or chipping, damaging workpiece threads or causing poor fit. | Ensures 100% yield rate, avoids scrap and rework caused by thread damage. |
| Anti-Rotation & Positioning | Absolutely Reliable. High-precision threads engage perfectly with the workpiece, completely preventing screw rotation during riveting. | Unreliable. Loss of grip due to thread wear often causes the screw to spin, creating scrap. | Achieves perfect rivets, ensures round, aesthetic rivet heads with uniform stress distribution. |
| Crack Resistance & Strength | Very High. Extreme compressive strength withstands huge radial riveting forces without cracking. | Average. Prone to stress cracks at the thread roots under high load. | Safe and reliable operation, eliminates risk of sudden tool fracture, protecting equipment and personnel. |
| Economy | Higher initial investment | Lower initial investment | Very low total cost of ownership. Superior lifespan and zero scrap rate deliver far greater value. |
