About this item

  • All‑in‑One 260PCS Metric M2.5 DIN912 Knurled Socket Head Cap Screw, Hex Nut, Nylon‑Insert Locknut & Flat Washer Assortment:This multi‑functional metric fastener kit includes fully threaded knurled anti‑slip socket head cap screws, matching M2.5 hex nuts, nylon insert locknuts and flat washers, total 260 pieces: ‑ M2.5 Knurled Socket Head Cap Screws: 4mm,6mm,8mm,10mm,16mm,18mm,20mm, 20pcs each ‑ M2.5 Standard Hex Nuts: 50pcs ‑ M2.5 Nylon‑Insert Locknuts: 20pcs ‑ M2.5 Flat Washers: 50pcs
  • All screws adopt M2.5 × 0.45mm coarse pitch, full‑length right‑hand threads; inner hex size 2.02–2.08mm, length measured from underneath the knurled cap head. Complies with DIN912 industrial standard, widely used for molds, small machinery, electronics and precision DIY assembly
  • Corrosion‑Resistant 304 Stainless Steel Construction:All screws, nuts and flat washers are manufactured from solid 304 stainless steel. It provides superior anti‑oxidation and chemical corrosion resistance and may be mildly magnetic. Burr‑free uniform coarse threads support repeated assembly and disassembly, more durable than carbon steel fasteners
  • Anti‑Slip Knurled DIN912 Socket Head Structure:Unique knurled textured surface on the cap head increases friction for quick manual pre‑tightening without tools; built‑in internal hex socket fits standard allen wrenches for stable torque fastening without slipping. Low‑profile round cap fits narrow limited clearance installation spaces
  • Dual Matching Nuts for Different Locking Needs:Comes with two types of supporting nuts: ordinary hex nuts for general fixed assembly; nylon insert locknuts with built‑in plastic ring, which generate friction to effectively prevent loosening under long‑term vibration, ideal for equipment with frequent movement.
  • Portable See‑Through Compartmentalized Plastic Storage Organizer:Equipped with lightweight split transparent plastic storage case. Knurled screws, hex nuts, locknuts and flat washers are stored in independent separated compartments for instant size identification. Compact lightweight box easy to carry for mold workshops, electronics repair stations and home precision assembly projects.

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.
