Quick Answers

Question Answer
What is this magnetic cup used for? It is used for mounting, fastening, holding, hanging, and retrieving metal objects.
How strong is this magnetic cup? The estimated cup-to-cup pull force is approximately 110 lbs under ideal conditions.
What screw size does it use? It works with M4 flat head screws, which are included.
Is it stronger than ceramic cup magnets? Yes, neodymium magnetic cups provide much stronger holding power than ceramic cup magnets.
Why is the magnet inside a steel cup? The steel cup protects the magnet and concentrates magnetic force on the contact surface.
Can it be mounted with a screw? Yes, the countersunk center hole is designed to recess an M4 flat head screw.

Product Overview

These 32 mm neodymium magnetic mounting cups are designed for strong holding, mounting, hanging, fastening, and retrieving applications. Each magnetic cup contains a powerful NdFeB neodymium magnet embedded inside a flat-base steel cup to maximize gripping force and improve durability.

The steel cup helps protect the magnetic material while concentrating magnetic force on the flat contact surface. This design provides significantly stronger holding power than ceramic cup magnets of similar size, making these mounting cups ideal for industrial, workshop, warehouse, garage, retail, and DIY applications.

This set includes 10 magnetic cups and matching M4 flat head screws for convenient installation.

What Is a Neodymium Magnetic Mounting Cup?

A neodymium magnetic mounting cup, also called a pot magnet or magnetic cup, is a strong rare earth magnet housed inside a steel cup. The steel cup redirects and concentrates the magnetic field toward the working surface, increasing holding force and protecting the magnet from impact or damage.

Mounting cups are commonly used when a magnet needs to be securely fastened with a screw while providing strong magnetic holding power.

How Strong Are These Magnetic Cups?

Each 32 mm magnetic cup has an estimated cup-to-cup pull force of approximately 110 lbs under ideal testing conditions.

Actual holding force may vary depending on:

  • Surface material

  • Steel thickness

  • Contact area

  • Mounting direction

  • Air gap

  • Surface cleanliness

  • Application conditions

For best performance, mount the magnetic cup securely and use it against a clean, flat, thick steel surface.

Neodymium Magnetic Cups vs Ceramic Cup Magnets

Feature Neodymium Magnetic Cups Ceramic Cup Magnets
Holding Power Much stronger Lower
Magnet Material NdFeB rare earth Ceramic ferrite
Size-to-Strength Ratio Excellent Moderate
Best Use Industrial, commercial, heavy-duty holding Light-duty holding
Mounting Countersunk screw hole Varies by design
Durability Steel cup protects magnet Usually less powerful

Neodymium magnetic cups are the better choice when strong holding power is needed in a compact mounting magnet.

Common Questions About These Magnetic Cups

What are these magnetic cups used for?

They are used for fastening, holding, hanging, mounting, and retrieving metal objects in industrial, commercial, workshop, and DIY applications.

Do these magnetic cups come with screws?

Yes. This 10-piece set includes M4 flat head screws.

What size are these magnetic mounting cups?

Each cup measures 32 mm in diameter and 6 mm thick, or approximately 1.26" diameter x 0.24" thick.

What size is the countersunk hole?

The countersunk hole measures 8.5 mm x 4.25 mm, or approximately 0.34" x 0.17".

Why does the steel cup increase holding power?

The steel cup concentrates the magnetic field on the flat contact surface, creating stronger gripping power than an exposed magnet of similar size.

Are these stronger than ceramic cup magnets?

Yes. Neodymium magnetic cups provide much stronger holding power than ceramic cup magnets.

Can these be used outdoors?

They may be used outdoors temporarily, but long-term outdoor or humid exposure may require additional protection.

Is the 110 lb pull force guaranteed?

No. The 110 lb cup-to-cup pull force is an estimate under ideal conditions. Actual performance should be tested for your specific application.
