Dual-Locking Snap-In Circuit Board Spacer for PCB-to-PCB Mounting
The JX-GMSPDLN Mini Support Post from JUXIN FASTENERS is a nylon PCB mounting component designed to support and separate two printed circuit boards at a specified distance.
Featuring a dual-locking snap-in design, the support post provides mechanical retention at both ends without requiring conventional screws or nuts.
It is suitable for PCB assemblies where controlled board spacing, electrical insulation, and simplified installation are important.
Material: Natural-color Nylon 66 (PA66)
Mounting Design: Dual-locking snap-in retention
Application: PCB-to-PCB spacing and mechanical support
Installation: Push-fit assembly into compatible mounting holes
Electrical Insulation: Non-metallic support structure
Available Support Lengths: 3.20–38.10 mm across the listed product range, subject to individual part confirmation
Flammability: UL 94 V-2 is stated in the existing product information; material-grade verification is required
JX-GMSPDLN PCB support posts can be considered for:
Industrial control circuit boards
Electronic control modules
Electrical cabinets and control equipment
Household appliance electronic assemblies
Industrial machinery electronics
PCB assemblies requiring mechanical separation between boards
Correct selection depends on the PCB mounting hole diameter, board thickness, required board-to-board spacing, and installation orientation.
Nylon 66 absorbs moisture, which may affect dimensional stability and mechanical properties. Designers should also evaluate operating temperature,
vibration, mechanical loading, and service environment before finalizing the support post.
JUXIN FASTENERS supports industrial buyers and OEM engineering teams with PCB mounting hardware selection and quotation based on confirmed product specifications.

Important: The dimensions above represent the existing published product information.
They must not be interpreted as a single universal configuration. Exact dimensions and tolerances require confirmation against the selected part drawing.
The existing product data lists two possible upper mounting hole diameters: 3.2 mm and 3.9 mm.
The lower mounting hole is listed as 3.18 mm.
Before PCB fabrication, engineers should confirm which upper hole diameter applies to the selected support post,
along with hole tolerances and board thickness requirements.
Do not assume that the two upper mounting hole sizes are interchangeable.
The published support length range is 3.20–38.10 mm.
The required spacing between the two circuit boards must be matched to the correct support post variant.
The published length range alone does not establish the exact installed PCB-to-PCB gap for every version.
For accurate selection, please provide:
Required PCB-to-PCB spacing in millimeters
Upper PCB mounting hole diameter
Lower PCB mounting hole diameter
Thickness of both PCBs
Required quantity per order
JUXIN FASTENERS can review the requested dimensions against available product configurations before quotation.
The JX-GMSPDLN series uses snap-in retention features at both ends.
The locking ends are designed to engage compatible PCB mounting holes and retain the boards in position.
Installation performance depends on hole dimensions, board thickness, material condition, and assembly geometry.
For applications exposed to vibration, shock, or repeated mechanical loading, retention performance should be validated under actual assembly conditions.
Nylon 66 offers electrical insulation and mechanical performance suitable for many electronic assembly applications.
However, material properties can vary with moisture conditioning, temperature, and the specific PA66 grade.
Chemical compatibility, dimensional stability, long-term mechanical loading, and flammability requirements should be reviewed for the intended application.
No universal load rating, temperature limit, or chemical resistance guarantee is implied without supporting material and product-specific test data.
