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 30mm – PACK OF 12 BLACK NYLON SPACERS Each pack contains 12 individual M4 x 30mm black nylon standoff spacers. The 4.3mm inner bore accommodates standard M4 bolts, machine screws, and threaded rod. The 30mm length creates a precise gap of exactly 30mm 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 | B07QWYY7H7 | | Best Sellers Rank | 3,218 in DIY & Tools ( See Top 100 in DIY & Tools ) 6 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 554 Reviews | | Exterior Finish | Black | | Exterior finish | Black | | Fastener Size | M3, M4, M5, M6, M8 | | Fastener Type | Flat Washer | | Fastener size | M3, M4, M5, M6, M8 | | 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 | 8 Millimetres | | Outside diameter | 8 Millimetres | | Screw Head Style | Round | | Size | 30mm | | Unit Count | 12.0 count | | Washer Type | Standoff | | Washer type | Standoff | ## Product Details - **Material:** Nylon - **Outside diameter:** 8 Millimetres - **Washer type:** Standoff - **Exterior finish:** Black - **Fastener size:** M3, M4, M5, M6, M8 ## Images ![M4 x 30mm 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/816q9esvOWL.jpg) ![M4 x 30mm 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 30mm 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 30mm 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 30mm 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality product *by on Reviewed in the United Kingdom 11 May 2026* Great quality product, item as described and ideal for the job ### ⭐⭐⭐⭐⭐ Strong, versatile. *by on Reviewed in the United Kingdom 11 May 2026* These can be used for a multitude of things, but I used them to extent some stair rods.
