Round Threaded Standoff

The Round Threaded Standoff is a precision-engineered cylindrical fastener featuring internal and/or external threading, designed to create accurate spacing between components in electronic, Automotive, and mechanical assemblies. Available in male, female, or male-female thread configurations, these round spacers ensure alignment, support, and insulation across structural and electronic layers.

With metric sizes ranging from M2 to M12, and standard lengths between 3mm to 100mm, our threaded round standoffs are manufactured to tight dimensional tolerances and comply with international standards such as ISO, MIL-STD-810G, and AEC-Q100.

Precision Machining & Manufacturing Process

Our round threaded standoffs are manufactured using high-precision CNC turning, thread rolling, and automatic machining centers. We maintain consistency with strict in-process controls and advanced CMM (Coordinate Measuring Machine) inspections.

Additional processing includes:

• Knurling or slotting for anti-rotation locking

• Deburring and ultrasonic cleaning for superior cleanliness

• GO/NO-GO thread testing and micrometer-level dimensional checks

Material Options

Custom materials available upon request (e.g., titanium for aerospace-grade needs).

Surface Treatment Options

• Anodized Aluminum: 5–25μm oxide layer, color-customizable

• Zinc-Nickel Plating: 8–12μm for 1000+ hours salt spray resistance

• Nickel or Chrome Electroplating

• Perfluoropolyether (PFPE) Lubricant Coating for anti-corrosion

FAQ – Frequently Asked Questions

Q1: What is the torque limit for installing round threaded standoffs?
A: It depends on size. For example, M2: 0.1–0.3Nm, M4: 1.2–2.0Nm, M6: 4.0–6.0Nm. Always refer to the datasheet.

Q2: Can you offer custom lengths or thread pitches?
A: Yes. We support custom machining with minimum order quantities depending on the material and dimension.

Q3: Are your standoffs RoHS and REACH compliant?
A: Yes. All materials and coatings are certified for RoHS, and documentation is available upon request.

Q4: How are standoffs packaged for export?
A: Vacuum-sealed + VCI bags for metal; nylon versions are UV-protected and moisture-isolated.

Q5: Do you offer testing reports?
A: Yes. COC, dimensional inspection reports, salt spray test data, and torque testing reports are available.
