Spacer

As professional Spacer manufacturers, we provide customers with comprehensive Spacer customization solutions. From dimensions and materials to surface treatment and structural design, all aspects can be flexibly adjusted according to customer requirements.

1. Spacer Size Customization

Size is one of the most critical parameters of a Spacer. Different equipment structures require different Spacer dimensions. We can manufacture precisely according to customer drawings, samples, or technical specifications.

Customizable dimensions include:

Length – Determines the spacing between two components; multiple length specifications are available.

Outer Diameter (OD) – Affects the strength and load-bearing capacity of the Spacer.

Inner Diameter (ID) – Matches different screw or bolt sizes such as M2, M3, M4, M5, M6, M8, etc.

Wall Thickness – Designed according to load-bearing requirements.

2. Spacer Material Customization

Different materials offer varying levels of strength, weight, corrosion resistance, and insulation performance. Selecting the appropriate material based on the application environment is essential.

Stainless Steel – Such as 201, 304, 316; excellent corrosion resistance, suitable for outdoor and industrial environments.

Carbon Steel – High strength and cost-effective, commonly used in machinery and industrial structures.

Aluminum – Lightweight and corrosion-resistant, ideal for electronic and communication equipment.

Brass – Good electrical conductivity, suitable for electronic and electrical applications.

Nylon – Provides insulation and corrosion resistance, commonly used for PCB board mounting.

3. Thread Customization

Many Spacers are used together with screws or bolts, so thread specification customization is very important. We can provide various thread configurations according to customer requirements.

Thread standards:

Metric Threads: M2, M2.5, M3, M4, M5, M6, M8, M10

Imperial Threads: #4-40, #6-32, #8-32, #10-24

Thread structures:

Female Spacer (Internal Thread)

Male Spacer (External Thread)

Male-Female Spacer (Standoff)

Unthreaded Spacer (Through Hole Spacer)

4. Surface Finish Customization

Surface finishing can enhance both the appearance and the corrosion and wear resistance of Spacers.

Zinc Plating – Common anti-rust treatment

Blue Zinc Plating – Improved corrosion resistance

Yellow Zinc Plating – Higher corrosion resistance

Nickel Plating – Bright surface with good wear resistance

Chrome Plating – Strong corrosion resistance

Black Oxide – Commonly used for industrial equipment

Anodizing – Typically applied to aluminum Spacers

5. Structural Customization

In many industrial applications, Spacers are not only used as simple spacing components but may also serve structural or positioning functions. Therefore, structural customization is important.

Round Spacer – The most common design

Hex Spacer – Easy to install using tools

Flanged Spacer – Provides improved stability

Custom Shape Spacer – Designed for specialized equipment structures

6. Precision Tolerance Customization

In many precision devices, the dimensional accuracy of Spacers is critical. For example, in electronic and automation equipment, even minor dimensional deviations may affect overall structural stability.

Standard Industrial Tolerance – Suitable for general equipment

Precision Machining Tolerance – Suitable for electronic devices

High-Precision Custom Machining – Suitable for precision instruments
