(10pcs) M3 X 20mm Male to Female Brass with Nickel plating Hex Threaded Standoff Spacer

Overview

The M3 x 20mm Male to Female Brass Hex Threaded Standoff Spacer (Nickel Plated) is a precision-engineered fastening and spacing solution designed for electronics and hardware assemblies. Featuring a 20mm hexagonal body with a female threaded socket on one end and a male threaded stud on the other, this standoff allows for rigid spacing, layered stacking, and elevated mounting of sensitive circuit boards and mechanical plates.

High Durability & Superior Corrosion Resistance

Machined from high-grade solid brass, these standoffs provide high tensile strength, precise dimensions, and resistance to thread stripping. The exterior is finished with an electro-deposited nickel-plated layer, providing a clean, metallic sheen alongside exceptional resistance to oxidation, moisture, rust, and everyday workshop wear.

Efficient Thermal & Electrical Spacing

Using standoffs ensures proper clearance between PCBs and metal chassis, preventing accidental short circuits, trace damage, and component contact. The 20mm gap also promotes passive airflow underneath high-draw components like motor drivers, MOSFETs, and microcontrollers to assist in thermal dissipation.

Common Applications

• PCB & Motherboard Mounting: Stacking Arduino, Raspberry Pi, ESP32 breakout boards, and flight controllers.

• Drones & FPV Quadcopters: Securing multi-layer PDBs (Power Distribution Boards), ESCs, and top/bottom carbon fiber plates.

• 3D Printers & CNC Controllers: Mounting mainboards, LCD displays, relay modules, and sensor brackets.
