MMS-D-X0 Specifications

  • Dimensions: This shows the name of each dimension and how it is measured in the image.
  • Magnetization Direction: The direction through which the magnet is magnetized. See our Magnetization Directions page for more details.
    Magnetization direction icon North (outer face)
  • Size: Size is the physical dimensions of the product using the standard unit of measure inches.
    1 x 0.25 Inch ( Diameter x Thickness )
  • Metric Size: Metric size is the physical dimensions of the product in metric millimeters.
    25.4 x 6.35 mm ( Diameter x Thickness )
  • Pull Force 1: Pull force case 1 represents a magnet attracting to a thick steel plate. Learn more about Magnet Pull Force Case 1.
    40.64 lb (18.43 kg)
  • Grade:
    N42
  • Max Operating Temp: Maximum operating temperature, also known as maximum service temperature, is the temperature at which the magnet may be exposed to continuously with no significant long-range instability or structural changes. Learn more in our Temperature and Neodymium Magnets article.
    176°F (80°C)
  • Material: This lists the name of the material each product is composed of.
    Neodymium (NdFeb)
  • BH Max: BH max is the Maximum Energy Product at the point on the B/H Curve that has the most strength, expressed in MGOe (MegaGaussOersteds). When describing the grade of a neodymium magnet, this number is commonly referred to as the "N" number, as in Grade N52 magnets. Learn more about Bh max in our glossary.
    42 MGOe
  • Tolerances: Dimensional tolerance specifies the allowed leeway for variations in manufacturing.
    ±0.01 in (.25mm)
  • Coating: Most neodymium magnets are plated or coated in order to protect the magnet material from corrosion. Check out our Custom Magnets for unplated magnets and other coatings not stocked for this size magnet. Learn more about all available platings and coating in our What Magnet Coating Should I Use? article.
    Nickel-Copper-Nickel (Ni-Cu-Ni)
  • Weight: This is the weight of a single magnet in ounces and grams. Variety packs (with mixed sizes) show the overall weight.
    0.8474 oz (24.02 g)
  • Br Max: Br max is also called "Residual Flux Density" and is when the magnetic induction remaining in a saturated magnetic material after the magnetizing field has been removed. This is the point at which the hysteresis loop crosses the B axis at zero magnetizing force, and represents the maximum flux output from the given magnet material. By definition, this point occurs at zero air gap, and therefore cannot be seen in practical use of magnet materials. Learn more about Br max in our glossary.
    13,200 Gauss
  • Hole Size: This is the size hardware that best fits the magnet hole size.
    #8 screw
  • Color: The color of the coating or plating on the product.
    Silver

Product Description

The mms-d-x0 female stud pot magnet has a 1" diameter and 1/4" thickness with a permanently attached female threaded shaft that accepts a #8 screw for secure mechanical attachment. The magnet is mounted in a steel cup with the north pole facing away from the cup and is coated with nickel-copper-nickel plating that provides a smooth, durable surface and helps protect the magnet from corrosion. Made from N42 neodymium grade material, this powerful pot magnet has a 40.64 lb pull force and a max operating temperature of 176°F (80°C).

The mms-d-x0 is a powerful round pot mounting magnet designed for projects that require a strong magnetic connection with a raised female threaded attachment point. Its threaded shaft makes it a versatile choice for woodworkers, fabricators, engineers, installers, and manufacturers connecting panels, brackets, fixtures, equipment, signs, displays, and custom components to steel surfaces. The raised mounting point is especially useful when the attached component needs clearance behind the magnet or when the magnet must be positioned away from the mounting hardware in equipment, enclosures, prototypes, and custom assemblies.

Common Applications

  • Panels & Enclosures - Fastening magnets to panels, covers, and enclosures to create removable magnetic attachments.
  • Signs & Displays - Securing signs, display panels, and identification plates to steel surfaces.
  • Brackets & Fixtures - Attaching brackets, fixtures, and fabricated components using a screw or bolt into the female threaded shaft.
  • Equipment Mounting - Adding removable magnetic mounting points to machinery, equipment, and industrial components.
  • Guards & Access Covers - Creating removable machine guards, inspection covers, and access panels that can be quickly detached.
  • Spaced Mounting - Using the raised threaded shaft where additional clearance is needed between the magnet and attached component.
  • Lights & Electronics - Fastening lights, sensors, cameras, and electronic devices to removable magnetic mounts.
  • Tool & Equipment Holders - Building magnetic holders and mounts for tools, accessories, and shop equipment.
  • Prototype Systems - Creating adjustable and removable connections for testing mechanical designs and mounting configurations.
  • Industrial Mounting - Building reusable magnetic attachment systems for manufacturing, fabrication, and maintenance environments.

Product Features

  • Female Threaded Shaft - Raised female threaded shaft accepts a compatible screw or bolt for secure mechanical attachment.
  • Steel Cup Construction - Neodymium magnet is housed inside a steel cup for a strong, durable mounting assembly.
  • Concentrated Holding Force - Steel cup redirects the magnetic field toward the exposed face to increase holding force against ferrous surfaces.
  • Secure Mechanical Connection - Female thread provides a reliable connection between the magnet and compatible hardware or components.
  • Protected Magnet Assembly - Steel cup surrounds the sides and back of the neodymium magnet, providing added physical protection.
  • Flat Magnetic Face - Broad contact surface provides secure attachment when placed directly against suitable ferrous metal.
  • Removable & Reusable - Magnetic attachment allows the assembly to be removed and repositioned without permanent fastening to the steel surface.
  • Permanent Magnet - Remains magnetized without requiring electricity, batteries, or an external power source.
  • Rare Earth Neodymium Magnet - The strongest type of permanent magnet available, providing exceptional strength for its size.
