A dependable step up in strength without changing size, these 1/4" x 1/16" N42 neodymium disc magnets are built for everyday performance. The 1/4" diameter gives you solid surface contact for a secure hold, while the 1/16" thickness keeps them low-profile and easy to place or embed. It’s a versatile combination that works across organization, crafts, and small builds.

Made from N42 grade rare earth neodymium, these magnets offer a stronger, more confident grip than standard lower-grade options, while still being easy to handle. The smooth nickel coating adds durability and a clean, polished finish. With 100 pieces in the pack, you’ll have plenty for projects, replacements, or keeping extras on hand.

Common Uses:

  • Holding notes, photos, and documents on metal surfaces
  • DIY crafts, models, and custom builds
  • Magnetic closures for boxes, lids, or panels
  • Embedding into wood, plastic, or resin
  • Organizing small tools, parts, or hardware
  • Office, classroom, or home use

Bottle-Cap Magnets and Thumbtacks

A homey take on the traditional locket, bottle caps inset with small black-and-white pictures, right, can be used as thumbtacks or magnets. Clear resin is poured into the caps to seal the photos and give them an appealing glossy finish.

Twist-off caps are better than conventional ones because they don't bend when removed. For appropriately small images, try cutting details from large photos. Or, if your software has a contact-sheet mode, use it to reduce pictures drastically.

Tools and Materials
1-inch circular craft punch
Craft glue
Bottle caps
Clear casting resin
Contact cement
Small magnets or thumbtacks

Magnets and Thumbtacks How-To
1. Using the craft punch, cut out pictures. Using craft glue, attach one picture to the inside of each bottle cap. Let dry.

2. Cover a work surface to protect it from spills, and lay caps on top. Following manufacturer's instructions for clear casting resin, fill each bottle cap to the rim. Let dry overnight.

3. Using contact cement, attach magnets or thumbtacks to the backs of the bottle caps. Let dry overnight before using.

    Great magnets for 3-d prints

    Strong magnets easily mounted in my 3d prints to hold parts together! Worth the price and I still haven't used them all! Easily the most versatile for assembling small 3-d prints.

    Tiny yet strong

    These are super small, I knew their size by the photo but something about sizes for me doesn't mean anything till I see them in person. They came in just a envelope, wish they'd came in a bag, with instructions to not get near electronics and other things that they can damage fingers and other things. While the magnets are strong they aren't strong enough to hold the other side through a finger.

    Strong little magnets

    Needed these for a project, bought a larger pack to have some for future use. Very strong and worked perfectly for some parts I 3D printed.

    Undersized

    These are 6mm not 1/4 inch (6.35mm) fine if you don't need precision but incorrectly labeled.

    Perfect for tool holders that have no magnet to hold bits tight

    Perfect for adding to tool holders that hold 1/4" bits so they won't fall out of the tool holder.
