Product Details
The Powerful Neodymium Threaded Pot Magnet is an engineering-grade magnetic assembly that combines the strength of sintered NdFeB with the mechanical convenience of a threaded mounting stud. The magnet is housed in a mild steel pot, which focuses the magnetic field onto the working surface and protects the magnet from impact damage. This design is widely used in industrial settings for quick-change fixtures, conveyor belt hold-downs, welding earth connections, and lifting attachments. With 20 years of rare-earth magnet expertise and full in-house production from sintering to final coating, we ensure that every unit delivers consistent pull force, superior corrosion resistance, and precise thread tolerance for reliable equipment integration.

Key Advantages of Threaded Pot Magnets
Concentrated holding force: the steel pot design focuses magnetism onto the contact face, achieving up to 220kg pull force while minimizing stray field – a key advantage of the Powerful Neodymium Threaded Pot Magnet.
Versatile mounting options: available with external stud or internal threaded hole, suitable for through-hole mounting, bracket fixing, and quick-connect fixturing.
Robust construction: the steel pot protects the brittle NdFeB magnet from chipping and impact, ensuring durability in industrial shop-floor environments.
Typical applications: welding jigs, inspection fixtures, magnetic tool holders, conveyor hold-downs, and equipment mounting in automotive and machine tool industries.
Advantages
Premium magnet grade: we use N42 NdFeB with dysprosium addition, ensuring the Powerful Neodymium Threaded Pot Magnet maintains its magnetic performance even in high-vibration or mildly elevated temperature conditions.
Precision thread machining: threads are rolled rather than cut, producing stronger threads with smoother surfaces and no stress raisers, certified to 6g tolerance for easy installation.
Comprehensive certification: all units comply with REACH, RoHS, and IATF16949; our electroplating line produces coatings that pass 300+ SGS tests for export to EU and US markets.
Flexible customization: we offer non-standard diameters, custom thread lengths, special coatings (Epoxy, PTFE, Zinc), and blind-hole designs for unique mounting requirements.
Packaging & Shipping
Each Powerful Neodymium Threaded Pot Magnet is individually packed in a bubble-wrap sleeve and foam-lined cardboard box to prevent surface scratches and demagnetization during transport. For bulk orders, we use double-walled corrugated cartons with internal partitions, ensuring individual separation. We support express shipping (DHL/FedEx) for urgent tooling requirements and sea freight for large-volume procurement. All shipments include magnetic hazard labels and MSDS documentation for safe air freight handling.
Production Process
Incoming raw material inspection (NdFeB blocks and steel bars).
Precision wire cutting of NdFeB magnet cores to specified dimensions.
Magnet grinding to ±0.02mm tolerance for pot insertion.
Steel pot machining and thread rolling (external stud or internal hole).
Magnet insertion and fixation (pressure-fit or adhesive).
Ni-Cu-Ni electroplating (automated barrel plating line).
Magnetization and pull-force testing (100% inspection).
Thread gauge check, visual inspection, and packaging.
FAQ
Q: Does the threaded stud come pre-assembled with a nut and washer?
A: The Powerful Neodymium Threaded Pot Magnet typically includes the magnet assembly with stud only. Nuts and washers can be added upon request at no extra charge for standard sizes.
Q: Can I use this magnet for lifting applications?
A: While it offers strong holding force, the Powerful Neodymium Threaded Pot Magnet is primarily designed for static holding and fixturing. For active lifting, we recommend our dedicated lifting magnet series with safety factors and lifting certifications.
