About this item
- Installation Steps: The flange metric bolts assembly can be used in everyday applications, such as car repair, motorcycle maintenance, and mechanical assembly. Use the tool to insert the screws into the connector. Install the flat washer, lock washer, and nut to secure and prevent loosening. To disassemble, simply unscrew in the opposite direction. Finally, store in our storage box for next use.
- 8.8 Grade Alloy Steel: M6 M8 M10 bolts are made of durable alloy steel with black oxide surface, and the strength reaches 8.8 grade, which has high tensile strength, tight and clear threads, and no burrs, suitable for various automotive, mechanical and DIY projects.

- Flange Head Design: The integrated flange on the bolt head acts as a built-in gasket, distributing pressure over a larger area, preventing loosening due to vibration, and making the connection more stable and secure.
- Widely Used: This nuts and bolts assortment kit comes in a box with extra-large, thick, fixed dividers, with size and quantity marked inside and out. Stickers correspond to the product compartments for easy storage and access; a must-have tool kit for professionals and DIY enthusiasts.

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.
