Made from durable, corrosion-resistant polyamide, they prevent short circuits and protect sensitive components in PCBs, robotics, and DIY projects. Universally compatible with all standard M4 bolts, these spacers combine reliability and versatility for professional-grade builds. ## Description M4 x 20mm Black Nylon Spacers Standoff Washers, Pack of 12 – Cylindrical Insulating Plastic Bushing for PCB, Electronics, Motherboard, Robotics & DIY : desertcart.co.uk: DIY & Tools ## 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 20mm – PACK OF 12 BLACK NYLON SPACERS Each pack contains 12 individual M4 x 20mm black nylon standoff spacers. The 4.3mm inner bore accommodates standard M4 bolts, machine screws, and threaded rod. The 20mm length creates a precise gap of exactly 20mm 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 | B07QW1P5FS | | Best Sellers Rank | 4,604 in DIY & Tools ( See Top 100 in DIY & Tools ) 8 in Spacers | | Brand Name | Universal Hardware | | Colour | Black | | Country Of Origin | Netherlands | | Customer Reviews | 4.5 4.5 out of 5 stars (58) | | Exterior Finish | Black | | Fastener Size | M3, M4, M5, M6, M8, M10 | | Fastener Type | Flat Washer | | Item Diameter | 7 Millimetres | | Item Thickness | 3 Millimetres | | Manufacturer | Fasteners Store | | Manufacturer Part Number | Black Nylon Spacers | | Material Type | Nylon | | Number Of Items | 12 | | Number of Pieces | 12 | | Outside Diameter | 7 Millimetres | | Screw Head Style | Round | | Set Name | M4 x 20mm Black Nylon Spacers Standoff Washers | | Size | 20mm | | Thread Size | M4 | | Unit Count | 12.0 count | | Washer Application | electronics, robotics | | Washer Compatibility | M4 bolts, M4 machine screws, M4 threaded rod | | 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 20mm 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/412Wn7DBmGL.jpg) ![M4 x 20mm 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/41CD0XzvS6L.jpg) ![M4 x 20mm 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/41XWOD2WUKL.jpg) ![M4 x 20mm 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/31SQwTRuf+L.jpg) ![M4 x 20mm 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/41UbTBKGNbL.jpg) ## Available Options This product comes in different **Size, Style** options. --- ## 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/173306288-m4-x-20mm-black-nylon-spacers-standoff-washers-pack-12](https://www.desertcart.com.cy/products/173306288-m4-x-20mm-black-nylon-spacers-standoff-washers-pack-12) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-10-11*
