## Description

M8 x 3mm 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 – 8.4mm INNER BORE, 12mm OUTER DIAMETER A precision-moulded cylindrical "through-hole" spacer with 8.4mm inner bore and 12mm 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.
- M8 x 3mm – PACK OF 12 BLACK NYLON SPACERS Each pack contains 12 individual M8 x 3mm black nylon standoff spacers. The 8.4mm inner bore accommodates standard M8 bolts, machine screws, and threaded rod. The 3mm length creates a precise gap of exactly 3mm 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 M8 FIT – COMPATIBLE WITH ALL STANDARD M8 BOLTS & SCREWS The 8.4mm inner bore is universally compatible with all M8 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.
