3*12mm Hexagonal nut brass COM14

DescriptionIn custom electronics, how you mount your circuit board is just as important as how you solder it. Bolting a bare PCB directly to a metal enclosure is a guaranteed way to cause a catastrophic short circuit. The M3x12mm Female Brass Hex Standoff solves this by acting as a physical pillar, lifting your hardware safely into the air while providing a rigid, secure mounting point.These spacers are precision-machined from solid brass and feature deep, clean internal threads ready to accept any standard M3 machine screw.The Female-Female AdvantageStandoffs come in two main varieties: Male-Female and Female-Female. This specific standoff is Female-Female, meaning it has a hollow, threaded core extending from both sides. This makes it incredibly versatile:Sandwich Mounting: You can place a screw through the bottom of your project box up into the standoff, and then drop another screw through your PCB down into the top of the standoff.Expansion: You can easily thread a Male-Female standoff directly into the top of this one to create taller custom pillars.Why Choose Solid Brass?While nylon standoffs are great for lightweight applications, they easily strip if you over-tighten the screws, and they can flex under physical stress. Brass is a far superior material for heavy-duty builds. It resists stripping, provides a much stronger anchor point for heavy components (like massive power supplies or multi-board stacks), and offers a premium, professional aesthetic to your finished product. Furthermore, the hexagonal outer shape allows you to firmly grip the pillar with a small wrench or needle-nose pliers while you tighten the screws, preventing the standoff from spinning freely.The 12mm Sweet SpotAt exactly 12mm tall, these standoffs provide just under half an inch of clearance. This is the ideal height for:Providing adequate cooling airflow underneath hot motor drivers.Ensuring sharp, through-hole solder joints on the bottom of your PCB do not scratch or short against the base of your enclosure.Stacking Raspberry Pi HATs or Arduino Shields with enough room for the header pins to seat properly.Key Features:Standardized Threading: Fully compatible with all M3 (Metric 3mm) screws, nuts, and other mounting hardware.Heavy-Duty Anchor: Solid brass construction will not shear or snap under vibration, making it perfect for moving robotics.Conductive Grounding: Because brass is a metal, these standoffs can be used to tie your PCB’s ground plane directly to a metal chassis if your design requires it.Technical Specifications:Thread Standard: Metric M3Gender Configuration: Female to FemaleStandoff Length: 12mmOuter Profile: HexagonalMaterial: BrassColor: Gold / BrassIdeal Applications:Mounting motherboards and custom PCBs inside project enclosuresBuilding multi-tier chassis for autonomous rovers and combat robotsCreating rigid frame structures for DIY quadcopters and dronesStacking multiple expansion boards (shields/HATs) securely
