Brass Round Clearance Spacer

We are known in the business sector for giving prevalent quality scope of Brass Round Clearance Spacer which is acclaimed in the business sector for their quality and high unwavering quality.

Brass Round Clearance Spacers are precision-engineered components designed to maintain accurate spacing between two surfaces in mechanical and electrical assemblies. Made from premium brass, they deliver exceptional corrosion resistance, electrical conductivity, and long-term durability. Their smooth finish and consistent inner clearance diameter ensure easy installation and reliable alignment. These spacers are widely used in PCB mounting, control panels, instrumentation, machinery, and custom fabrication projects where dependable performance and stability are essential.

We work with the backing of our very much prepared representatives who assist us with providing practical and propelled items mind complete quality certification. These are supplied at the most sparing business sector value range.

our product rang Brass Spacers Or Standoffs, Brass Female-Female Standoffs and Brass Nuts etc.

To generate or maintain a clearance between the two things, these tiny bits of material are positioned between the screw head and surface. Depending on the amount of space needed for your applications, this range of spacers is available in a variety of different sizes and lengths (2 mm to 8 mm spacer).

These spacers are compatible with many screws, including self-tapping screws, machine screws, and studding. They have a round body shape with plain bore holes. These spacers are made of nickel-plated brass, which resists rust and corrosion and increases their durability and lifespan.

Technical Details of Brass Round Clearance Spacer

Material:

• Premium brass (commonly C36000 / free-cutting brass)
• Good conductivity, corrosion resistance, and machinability

Spacer Type:

• Round clearance spacer (unthreaded bore)
• Provides precise spacing with smooth internal clearance hole

Dimensions:

• Outer diameter (OD): e.g., 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm (varies by part number)
• Length/Height: e.g., 3 mm – 50 mm or custom lengths available
• Internal bore diameter: slightly larger than mating bolt/shank (clearance fit)
– Typical clearance sizes: matching common fasteners (e.g., clearance for M2, M3, M4, M5, etc.)

Tolerance:

• Outer diameter tolerance: ±0.05 mm to ±0.1 mm
• Length tolerance: ±0.1 mm (varies by specification)
• Bore tolerance: engineered for clearance fit (H9 / standard clearance class)

Mechanical Properties:

• Tensile strength: ~300–500 MPa (depends on brass grade)
• Hardness: ~60–90 HRB (depending on machining and brass grade)
