Review: Spacer kit - Good quality ## Features - BLACK NYLON (POLYAMIDE) – NON-CONDUCTIVE, LIGHTWEIGHT & DURABLE Manufactured from high-quality black nylon (polyamide PA6) — electrically non-conductive, naturally non-magnetic, and immune to rust or corrosion. Ideal for electronic assemblies, PCB mounting, and any application where metal spacers would conduct electricity, short circuits, or scratch sensitive components. Black colouring also provides good UV stability for outdoor or sunlight-exposed installations. - CYLINDRICAL STANDOFF DESIGN – 4.3mm INNER BORE, 7mm OUTER DIAMETER A precision-moulded cylindrical "through-hole" spacer with 4.3mm inner bore and 7mm outer diameter. The screw passes straight through and the spacer creates a precise, repeatable gap between two surfaces — typically used to lift a PCB or component off a metal chassis, separate two layers of material, or provide insulation at a fixing point. No internal thread — the screw threads into a nut, tapped hole, or PEM insert at the other end. - M4 x 15mm – PACK OF 12 BLACK NYLON SPACERS Each pack contains 12 individual M4 x 15mm black nylon standoff spacers. The 4.3mm inner bore accommodates standard M4 bolts, machine screws, and threaded rod. The 15mm length creates a precise gap of exactly 15mm between the mating surfaces. Cleanly moulded with no flash or burrs — ready for direct assembly use. - ESSENTIAL FOR PCB, ELECTRONICS & ROBOTICS PROJECTS Black nylon standoffs are the standard mounting hardware for printed circuit boards, motherboards, Raspberry Pi, Arduino, drone PCBs, robotics controllers, 3D printer electronics, and any project requiring a non-conductive electrical separation between board and chassis. The insulating properties prevent short circuits, electrical interference, and damage to sensitive components during installation and operation. - UNIVERSAL M4 FIT – COMPATIBLE WITH ALL STANDARD M4 BOLTS & SCREWS The 4.3mm inner bore is universally compatible with all M4 metric bolts, machine screws, button head screws, and threaded rod across all major brands. Combine multiple spacers in series for precise custom heights, or use with nylon nuts and washers for a fully non-conductive assembly. Available in M3, M4, M5, M6, M8, and M10 across lengths from 3mm to 30mm — browse our store for the complete nylon spacer range. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07QWYYRCQ | | Best Sellers Rank | 5,339 in DIY & Tools ( See Top 100 in DIY & Tools ) 9 in Spacers | | Brand Name | Universal Hardware | | Colour | Black | | Compatible Groove Diameter | 4.2 Millimeters | | Country Of Origin | Netherlands | | Customer Reviews | 4.5 out of 5 stars 58 Reviews | | Exterior Finish | Black | | Exterior finish | Black | | Fastener Size | M3, M4, M5, M6, M8, M10 | | Fastener Type | Flat Washer | | Fastener size | M3, M4, M5, M6, M8, M10 | | Finish Types | matte | | Item Diameter | 8 Millimetres | | Item Thickness | 3 Millimetres | | Item thickness | 3 Millimetres | | Manufacturer | Fasteners Store | | Manufacturer Part Number | Black Nylon Spacers | | Material | Nylon | | Material Type | Nylon | | Number Of Items | 12 | | Number of Pieces | 12 | | Outside Diameter | 7 Millimetres | | Outside diameter | 7 Millimetres | | Screw Head Style | Round | | Set Name | M4 x 15mm Black Nylon Spacers Standoff Washers, Pack of 12 | | Size | 15mm | | Thread Size | M3, M4, M5, M6, M8 | | Unit Count | 12.0 count | | Washer Application | PCB mounting, electronics, robotics | | Washer Compatibility | bolts, screws, threaded rod | | Washer Type | Standoff | | Washer type | Standoff | ## Product Details - **Exterior finish:** Black - **Fastener size:** M3, M4, M5, M6, M8, M10 - **Material:** Nylon - **Outside diameter:** 7 Millimetres - **Washer type:** Standoff ## Images ![M4 x 15mm Black Nylon Spacers Standoff Washers, Pack of 12 – Cylindrical Insulating Plastic Bushing for PCB, Electronics, Motherboard, Robotics & DIY - Image 1](https://m.media-amazon.com/images/I/71ltyjNghcL.jpg) ![M4 x 15mm Black Nylon Spacers Standoff Washers, Pack of 12 – Cylindrical Insulating Plastic Bushing for PCB, Electronics, Motherboard, Robotics & DIY - Image 2](https://m.media-amazon.com/images/I/71Sf2sxwsdL.jpg) ![M4 x 15mm Black Nylon Spacers Standoff Washers, Pack of 12 – Cylindrical Insulating Plastic Bushing for PCB, Electronics, Motherboard, Robotics & DIY - Image 3](https://m.media-amazon.com/images/I/515woxVWhAL.jpg) ![M4 x 15mm Black Nylon Spacers Standoff Washers, Pack of 12 – Cylindrical Insulating Plastic Bushing for PCB, Electronics, Motherboard, Robotics & DIY - Image 4](https://m.media-amazon.com/images/I/81zRRs0DuHL.jpg) ![M4 x 15mm Black Nylon Spacers Standoff Washers, Pack of 12 – Cylindrical Insulating Plastic Bushing for PCB, Electronics, Motherboard, Robotics & DIY - Image 5](https://m.media-amazon.com/images/I/614IhZPt8QL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: How do I select the length of the spacer???** A: Size name is the length of the spacers. **Q: If I would buy the m8, 20mm,eould it be possible to swap out 2 for the 10mm?** A: Unfortunately not. those are prepacked items. **Q: Hi I need 2 x spacers to convert a 20mm hole to internal diameter 8mm on a wheel, what should I order pls** A: You will need a spacers with OD 20mm, our M8 Spacers have 15.5mm. You can get M10 with OD 20mm but the hole is 10.5mm. **Q: Are these made of solid plastic? I want to use them as part of a foot arrangement. Thanks** A: They have a hole to allow a screw through them length wise but they are pretty solid - you can't bend or squash them easily. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality spacers *by D***B on 2 September 2026* Good quality spacers, the size was accurate and they have done the job I bought them for. ### ⭐⭐⭐⭐⭐ Spacer kit *by D***D on 10 January 2026* Good quality ### ⭐⭐⭐⭐⭐ Happy with what I bought these for *by N***B on 6 April 2025* Not sure what these are meant for but screws were too long on a bedside cabinet so used these rather than sawing the screws down. Worked perfectly. ## Frequently Bought Together - M4 x 15mm Black Nylon Spacers and Standoff Washers for M3, M4, M5, M6, M8 Screws, Lengths 3mm to 30mm (Pack of 12) - AMLOOPH M8 Bolts, M8 X 20mm Hex Socket Button Head Machine Bolts/Screws -Fully Threaded A2 304 Stainless Steel Hex Socket Screws M8 (Pack Of 20) - AMLOOPH M6 Screws, M6 X 25mm Allen Socket Head Cap Screws/Bolts - 6mm Diameter Fully Threaded M6 Bolts 25mm A2 Stainless Steel Long Hex Socket Bolt Coarse (Pack Of 20） --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/175041943-m4-x-15mm-black-nylon-spacers-standoff-washers-pack-12](https://www.desertcart.com.cy/products/175041943-m4-x-15mm-black-nylon-spacers-standoff-washers-pack-12) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-10-03*
