About this item

  • 【Standardized Metric Sizes】The M3-0.5 hex socket head cap screws set comes with 8 commonly used lengths—M3×8mm, M3×10mm, M3×12mm, M3×16mm, M3×18mm, M3×20mm, M3×30mm, and M3×45mm—ideal for routine installations and repairs. They meet standard metric specifications, with an average error of less than 0.01mm.
  • 【Premium 12.9 Grade Alloy Steel】This M3 bolt, nut, and washer assortment kit is crafted from high-strength 12.9-grade alloy steel, ensuring exceptional durability and load-bearing capacity. The high-strength steel resists wear, corrosion, and heavy loads, making it ideal for harsh environments.
  • 【Wide Applications】Our metric bolt and nut sets come in boxes with thick, fixed dividers. Both internal and external labels mark the corresponding screw sizes and quantities for easy storage and access. The sleek box is convenient to carry in your daily tool bag, and also makes a great gift for professionals and hobbyists who regularly repair furniture, cars, and more.
  • 【Easy to Use】This M3 screw kit is ideal for daily furniture assembly and mechanical repairs. When using it, simply pick up the screws with tweezers, insert them into the hardware that needs to be connected, then tighten them with the included M3 wrench. Finally, install the nuts and flat washers to prevent loosening. Disassembly is just as easy—simply unscrew in the opposite direction.
  • 【Smart Storage Box】The metric machine screw kit comes in a durable, compartmentalized case with clear size labels—so you can spot the right screw instantly. It keeps your workspace tidy and speeds up project progress, making every job smoother.

FAQ

How can I confirm that a product is suitable for my application?


Review the product description, dimensions, materials, ratings, connection types, and compatibility information before ordering. Industrial requirements vary, so consult the equipment manufacturer or a qualified professional if you are uncertain.

Do you provide installation or technical advice?


We can help clarify information shown on a product page, but we do not provide engineering, installation, or workplace-safety advice. Products should be selected, installed, and operated by appropriately qualified personnel where required.

Can I change or cancel my order after placing it?


Contact us as soon as possible at ruleindgalein@gmail.com. We will try to accommodate your request, but changes or cancellations cannot be guaranteed once an order has entered processing or shipment.

When will my order be shipped?


Processing and delivery estimates may vary depending on the product, destination, inventory availability, and carrier. Please review the shipping information provided at checkout and our Shipping & Delivery Policy for additional details.

How can I track my order?


When tracking becomes available, it will be sent to the email address used for your order. Tracking activity may take some time to appear after the carrier receives the shipment.

Why did my order arrive in more than one package?


Items from the same order may be fulfilled or shipped separately. As a result, packages can arrive at different times and may have separate tracking numbers. You will not be charged additional shipping solely because an order is divided into multiple shipments.

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


Contact us promptly at ruleindgalein@gmail.com with your order number, a description of the issue, and clear photographs of the item, packaging, shipping label, and any visible damage. Keep all packaging until we provide further instructions.

Can I return an item if it is not suitable?


Eligible items may be returned in accordance with our Return & Refund Policy. Return conditions, exclusions, time limits, and any applicable costs depend on the item and circumstances. Please contact us before sending anything back.

Do you offer bulk quantities or business purchasing?


Availability of larger quantities varies by product. Email us with the product link, desired quantity, required specifications, and delivery location, and we will let you know whether suitable options are available.
