288pcs Black Nylon Spacers Kit, 18 Sizes 3-25mm for M3-M6 Screws

Professional Spacing Solutions: The Kalote 288PCS Black Nylon AssortmentWhether you are building a custom PC, repairing a piece of vintage furniture, or prototyping a new electronic device, the wrong spacing can lead to disaster. Metal spacers are heavy and conductive; cheap plastic ones crack under pressure. Kalote provides the high-quality alternative with our comprehensive 288-piece non-threaded nylon spacer kit.Why Nylon Matters for Your BuildNylon 6/6 is the industry standard for a reason. It is incredibly tough yet lightweight, providing enough "give" to prevent surface damage while remaining rigid enough to support structural loads. Its natural electrical insulation makes it the go-to material for mounting motherboards, sensors, and power supplies where metal standoffs pose a risk of shorting components.Solve Installation FrustrationsWe listened to the common complaints about "universal" kits. That’s why our kit includes specific lengths (up to 25mm) that competitors often skip. These spacers solve the headache of screw-through holes being too wide or too narrow, providing a clean, professional aesthetic for your finished projects. No more "hacking" it with stacks of washers; use a single, solid spacer for maximum stability.What’s Included in the Box?A massive 288-piece collection featuring 16 pieces each of 18 specific sizes: M3 Series: 3mm, 6mm, 10mm, 18mm, 25mm lengths (7mm OD) M4 Series: 3mm, 5mm, 8mm, 15mm lengths (8mm OD) M5 Series: 3mm, 6mm, 10mm, 18mm, 25mm lengths (9mm OD) M6 Series: 5mm, 8mm, 15mm, 20mm lengths (11mm OD)Tip: These are non-threaded spacers. Ensure your screw diameter matches the M-rating (e.g., use an M4 screw for an M4 spacer) for the best fit.

• 1. PRECISION NON-THREADED STABILITY - Stop struggling with loose, shaky components. Our round spacers feature a precision-engineered smooth bore for M3, M4, M5, and M6 screws. Unlike threaded standoffs that restrict movement, these non-threaded sleeves allow for flexible alignment, ensuring a professional, snug fit for your PCB boards and hardware repairs.
• 2. HIGH-STRENGTH INSULATING NYLON - Upgrade your project with durable, lightweight black nylon. Engineered for high-impact resistance and electrical insulation, these plastic spacers protect sensitive electronics from short circuits and vibrations. They won’t rust like metal or degrade like soft rubber, making them the ideal choice for long-term outdoor and indoor use.
• 3. 18 VARIED SIZES FOR ANY PROJECT - Say goodbye to missing the "just right" spacer. This 288-piece kit covers 18 essential dimensions, ranging from 3mm to 25mm in length. From low-profile M3 PC fan mounts to heavy-duty M6 furniture leveling, you’ll always have the exact thickness required to solve clearance issues and create perfect gaps.
• 4. MULTI-SCENE VERSATILITY & DIY HELPER - Designed for the modern maker and technician. These versatile unthreaded standoffs are perfect for 3D printer assembly, computer motherboards, automotive panel gaps, and securing home appliances. They act as protective bushings, preventing screw heads from crushing delicate plastic surfaces while maintaining rigid spacing.
• 5. REINFORCED CASE & EASY ORGANIZATION - No more sorting through a mess of black plastic. Our spacers come in a heavy-duty, labeled organizer tray with secure latches to prevent mixing during transit. Each compartment is clearly marked with M-sizes and lengths (e.g., M5x9x18mm), allowing you to identify the correct part in seconds and keep your workbench tidy.
