Hex Spacer

A hex spacer, also known as a hexagonal spacer or hex standoff spacer, is a mechanical component designed to create space between two objects—typically circuit boards or mounting surfaces—while maintaining structural integrity. Featuring a six-sided profile, hex spacers are commonly used in PCB mounting, motherboard assembly, and electronic enclosures where both alignment and insulation are critical.

Whether you're working on DIY electronics, robotics systems, or high-end computer assemblies, hex spacers provide a reliable and precise solution for spacing and support.

Product Features

• Hexagonal Design: Offers excellent wrench grip for easy installation and removal

• Precision Threading: Available in male-female, female-female, and male-male configurations

• Size Versatility: Offered in M3, M4, M5, M6 threads with lengths from 5mm to 50mm (e.g., M3 hex spacer, 10mm hex spacer)

• Electrical Insulation (Nylon Types): Ideal for sensitive circuit board applications

• Corrosion Resistance: Stainless Steel and brass variants available for harsh environments

Manufacturing Process

All our hex spacer standoffs are manufactured using CNC machining and automatic lathe turning, ensuring tight dimensional tolerances and smooth surface finishes. The production includes:

1. Material Cutting

2. Hex Profile Machining

3. Threading (Internal/External)

4. Deburring and Surface Finishing

5. Quality Control Inspection

Material Options

We offer a wide range of material choices to suit different industrial applications:

• Stainless Steel Hex Spacer – Excellent for corrosion resistance and strength

• Structural support in a robotic arm with stainless steel hex spacers

Frequently Asked Questions (FAQ)

Q1: What is the difference between a hex spacer and a hex standoff?
A: While terms are often used interchangeably, a hex spacer typically refers to an unthreaded or pass-through part, while a hex standoff spacer has internal or external threads for screwing into place.

Q2: Can I get custom sizes for hex spacers?
A: Yes, we offer custom hex spacers in terms of thread size, length, and material to meet your specific needs.

Q3: Are hex spacers reusable?
A: Yes, metal hex spacers like brass or stainless steel can be reused if undamaged. Nylon ones may degrade over time in high-stress environments.

Q4: Do you support bulk orders and OEM packaging?
A: Absolutely. We support bulk production, labeling, and packaging as per customer requirements.
