About this item

  • 18 VERSATILE SIZES FOR ANY PROJECT: With 306 pieces and 18 distinct sizes (M3 to M6), this kit eliminates the frustration of being "one spacer short." Whether you're filling a 3mm gap or a 25mm height requirement, you’ll find the precise fit for your bolt and standoff needs without trips to the hardware store.
  • PREMIUM INSULATING NYLON MATERIAL: Crafted from high-density black nylon, these spacers offer superior electrical insulation and corrosion resistance compared to metal. They are lightweight yet rigid enough to resist deformation under pressure, making them ideal for sensitive electronic assemblies.
  • PRECISION NON-THREADED DESIGN: These circular spacers feature smooth, non-threaded bores designed for easy bolt pass-through. Unlike brittle plastic competitors, our spacers provide a stable, vibration-dampening buffer that protects your PCB boards and delicate surfaces from scratches.
  • OPTIMIZED FOR 3D PRINTING & DIY: Solve the "uneven surface" pain point in 3D printer builds and robotics. These spacers are specifically sized for M3-M6 hardware, ensuring perfect alignment for motherboards, cooling fans, and mechanical linkages in your custom DIY projects.
  • DURABLE & ORGANIZED STORAGE: Stop wasting time digging through messy bins. Our set comes in a heavy-duty, labeled organizer box with secure latches to prevent sizes from mixing. Each compartment is clearly marked with dimensions for rapid identification during intensive assembly work.

FAQ

What types of products does Stemora offer?


Stemora offers supplies for science experiments, microscopy, biology learning, measurement, laboratory organization, electronics, robotics, coding education, 3D printing, maker projects, and classroom activities. Available products and specifications may change over time.

Are Stemora products suitable for children?


Recommended ages vary by product. Please review the product description, manufacturer guidance, included warnings, and required skill level before purchasing. Products containing small parts, tools, electrical components, glass, or chemicals may not be suitable for young children.

Is adult supervision required?


Adult supervision is recommended for children and students, especially when using electrical components, sharp tools, heated equipment, glassware, small parts, or experiment materials. Customers are responsible for following all product instructions and safety precautions.

Can these products be used at home and in classrooms?


Many products may be suitable for classrooms, home learning, science projects, maker spaces, and hobby activities. Suitability depends on the specific product, learning environment, user experience, and intended activity.

How can I check what is included with a product?


Please review the product title, description, specifications, images, package quantity, and included-components section before ordering. Items shown for demonstration or scale in product images may not always be included.

How do I know whether an electronic or robotics part is compatible?


Check the listed dimensions, voltage, connector type, board compatibility, operating requirements, and supported platforms. Compatibility is not guaranteed unless it is specifically stated on the product page. Contact us before ordering if you need clarification.

When will I receive tracking information?


Tracking information is generally provided within 3–5 business days after an order is confirmed. In some cases, processing may take approximately 7–8 business days. Delivery may require an additional 4–5 business days after tracking becomes available, depending on the carrier and destination.

Why did my order arrive in separate packages?


Products in the same order may be shipped from different fulfillment locations. As a result, items may arrive separately and have different tracking numbers. You will not be charged additional shipping fees solely because an order is divided into multiple packages.

Can I change or cancel my order?


Contact us as soon as possible at vaioamaonaoak@gmail.com. We will try to assist, but changes or cancellations cannot be guaranteed once an order has entered processing or has been shipped.

What should I do if an item arrives damaged, defective, or incorrect?


Contact us promptly at vaioamaonaoak@gmail.com with your order number, a description of the issue, and clear photographs of the item, packaging, and shipping label. Please retain the product and original packaging while we review your request. Eligibility and available resolutions are subject to our Return & Refund Policy.
