Spacer – M3 Double-Pass Hexagonal Brass Spacers M3 x (10/15/20/25/30/35/40)mm

M3 Brass Spacer Overview

Our M3 double-pass hexagonal brass spacers provide precision spacing, mechanical support, and reliable electrical isolation for PCB assemblies. Made from corrosion-resistant brass, these spacers combine durability with conductivity for long-term performance in industrial and DIY projects.

Key Features of the M3 Hex Spacer

• Hexagonal body for easy gripping with pliers or wrenches
• Double-pass (male-female) M3 threading enables secure stacking of boards
• Corrosion-resistant brass material for long service life
• Prevents electrical shorts while allowing airflow beneath components
• Precision-machined for tight tolerances and consistent spacing

Technical Specifications

• Thread size: M3 (male/female double-pass)
• Material: Brass (corrosion-resistant)
• Shape: Hexagonal (for tool engagement)
• Lengths available: 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm
• Finish: Natural brass (conductive)

Benefits for Electronics and Mechanical Builds

• Secure mounting and alignment for PCBs, control panels, and modules
• Improved cooling by creating a gap for airflow under components
• Reduced risk of short circuits through reliable insulation and spacing
• Reusable and easy to install or replace during maintenance and upgrades

Common Applications

• Raspberry Pi and Arduino projects
• Motherboards and PC cases
• Robotics, drones, and automation control boards
• IoT modules, sensor stacks, and embedded systems
• Test rigs, CNC assemblies, and electrical enclosures

Installation Tips

• Hand-start screws to avoid cross-threading before final tightening with a screwdriver or wrench
• Use the hex body to hold the spacer steady when tightening
• Pair with M3 screws of appropriate length to ensure secure fastening without protrusion
• For stacked PCBs, use double-pass threading to join modules directly without extra hardware

Why Choose These M3 Standoff Spacers

These brass hex pillars deliver a balance of electrical conductivity and mechanical strength. They resist rust and wear, offering dependable performance in hobbyist and industrial environments. Precision machining ensures consistent heights across your build, which is critical for multi-board stacks and compact enclosures.

Ordering and Compatibility

Available in seven lengths to fit a wide range of projects. Compatible with standard M3 screws and widely used PCB hole patterns. Ideal choice for engineers, makers, educators, and repair technicians in Pakistan and beyond.
