M3 Hexagon Nylon Plastic Standoff Spacer — Lock Push Clip Snap-In for PCB 4mm Hole 1.6mm Board

M3 Hexagon Nylon Plastic Standoff Spacer — Lock Push Clip Snap-In for PCB 4mm Hole, 1.6mm Board

M3 hexagonal nylon plastic snap-in lock clip standoffs for PCB and circuit board mounting. The push-clip mechanism snaps through a 4mm chassis hole and locks in place, securing a 1.6mm thick PCB without screws or tools. The hexagonal body provides a wrench grip for controlled installation and removal.

Key Specifications

Why Choose M3 Hex Lock Clip Standoffs?

• Push-in snap lock — snaps through 4mm chassis hole and locks; no screws or tools needed for installation
• M3 female thread — accepts M3 machine screw from above for additional PCB retention security
• Hexagonal body — can be gripped with pliers or hex wrench for controlled removal
• Non-conductive nylon — electrically isolates PCB from metal chassis
• Standard 1.6mm PCB compatibility — fits the most common PCB thickness

Typical Applications

• PCB mounting in plastic and metal enclosures (tool-free snap-in)
• Arduino, Raspberry Pi, and SBC mounting in snap-fit enclosures
• Consumer electronics PCB assembly (TV, router, set-top box)
• Industrial control panel PCB quick-mount
• LED driver and power supply PCB chassis mounting
• Automotive ECU and control module PCB mounting

Compatible With

Chassis holes of 4mm diameter. Accepts M3 machine screws from above. Compatible with standard 1.6mm PCBs with 3.2mm mounting holes. Suitable for: Arduino UNO/Mega, Raspberry Pi 3/4/5, ESP32 development boards, and most standard PCB designs.

FAQ

Q: Do I need a screw to use these standoffs?
A: No. The snap-in clip secures the standoff in the chassis hole without screws. However, the M3 female thread allows you to add an M3 screw from above for additional PCB retention if needed.

Q: What chassis hole size do I need?
A: These require a 4mm diameter chassis hole. For 3.5mm holes, use the push-in rivet snap clip standoff variant instead.

Q: How do I remove these after installation?
A: Use a flat-head screwdriver or spudger to pry the snap clip inward, then pull the standoff out. The hex body can also be gripped with pliers for controlled removal.
