20kg Magnetic Hooks – Overview

For European and Asian industrial buyers working with metric specifications, 20kg magnetic hooks provide a precise holding capacity of 20 kilograms (approx. 44 lbs) on 8mm steel plate. These compact magnetic hooks combine a grade N45 neodymium magnet with a lathe‑turned steel cup, featuring a recessed M5 thread for eyelets or fixed hooks. Unlike imperial‑rated products, our 20kg magnetic hooks are designed around metric tooling - ideal for automotive jigs, exhibition stands, and retail display systems. Backed by 30 years of magnetic hook manufacturing and full IATF16949/ISO9001/REACH/RoHS/EN71/CE/CP65/CHCC compliance.

Product Details – 20kg Magnetic Hooks

The 20kg magnetic hooks belong to our mid‑force series, optimized for repeated mounting on ferromagnetic surfaces without permanent fixtures. Each unit consists of: a sintered NdFeB magnet (diameter 18mm × thickness 6mm), a deep‑drawn or lathe‑tuned SPCC steel cup (zinc‑nickel plated, 72h salt spray), and a 304 stainless steel hook with 360° rotation. The magnetic circuit is semi‑closed: the steel cup redirects flux to the contact face, achieving 4× the pull of a bare magnet of equal volume. We inject epoxy between magnet and cup to prevent off‑center shifting under vibration. All 20kg magnetic hooks are magnetized after final assembly and verified on a digital tension gauge.

Key Features & Applications – 20kg Magnetic Hooks

Single‑side flux concentration – magnetic field largely absent on sides and back, safe for control panels or painted surfaces.

Epoxy encapsulation – prevents magnet shift under repetitive shock (tested to 10,000 cycles).

Customizable hook – replaceable with carabiner, rubber‑coated hook, or magnetic base without threads.

Typical sectors – automotive assembly (parts holding), retail pop‑up displays, industrial cable organizers, workshop pegboard attachments, door stops, and magnetic tool holders for CNC machines.

Why Choose These 20kg Magnetic Hooks?

Full in‑house production: from magnet sintering to cup stamping and final assembly, no outsourcing.
Each 20kg magnetic hook individually pull‑tested on a calibrated force gauge (standard deviation ≤ 0.5 kg).
20% lower cost than German or Japanese equivalents for same N45 performance.
Fast prototype: 3D drawing to physical sample in 8 working days for custom diameters.
Shipping documents including EN10204 3.1 certificate for material traceability.

Packaging & Shipping

Standard export packaging: anti‑static bubble wrap + individual PE bag, then 200pcs per corrugated carton (385×285×215mm). Cartons are reinforced with edge protectors. For sea freight, we use fumigation‑free pallets with strapping. Air shipment via DHL/FedEx available for samples. All orders include REACH/RoHS/EN71 declaration and packing list.

After‑Sales & Quality Assurance

24‑month warranty against loss of magnetic force exceeding 15% of rated 20kg. If any 20kg magnetic hooks fails in‑field, we provide replacement within 1 week. Technical support includes torque recommendations for the recessed M5 thread (max 3 N·m). Free replacement for any batch that fails the 20kg pull test during buyer's incoming inspection.
