Nylon M4×8mm Phillips Pan Head Screw Non-Conductive 20-Pack

Nylon M4×8mm Phillips Pan Head Screw — Non-Conductive, 20-Pack

M4×8mm nylon Phillips pan head screws provide the non-conductive, non-magnetic properties of nylon fasteners in the larger M4 thread size, delivering greater clamping force than M3 nylon screws for heavier PCBs, larger panels, and structural electronics enclosure assembly where electrical isolation is still required. The 8mm length provides full thread engagement in standard M4 standoffs and tapped holes.

Key Specifications

Why Choose M4 Nylon Screws?

• M4 greater clamping force — M4 nylon screws provide approximately 2× the clamping force of M3 nylon screws; suitable for heavier PCBs and larger panel assemblies requiring electrical isolation
• Electrically non-conductive — PA66 nylon eliminates risk of short circuits between PCB traces and screw body
• Non-magnetic — no magnetic interference for sensors, RF circuits, and precision instruments
• 8mm standard length — optimal thread engagement in standard M4 standoffs (18mm, 20mm, 30mm, 40mm) and M4 tapped holes
• Lightweight — nylon construction for weight-critical applications

Typical Applications

• Heavier PCB mounting to M4 nylon standoffs in electronics enclosures
• Large panel mounting requiring electrical isolation from metal chassis
• Industrial electronics enclosure PCB mounting (M4 for heavier boards)
• Power supply board mounting with electrical isolation from chassis
• Sensor array and module mounting requiring non-magnetic fasteners
• RF and microwave circuit board mounting (non-conductive, non-magnetic)

Compatible With

• M4 nylon standoffs (M4×18mm M-F, M4×20/30/40mm F-F)
• M4 nylon hex nuts
• M4 brass standoffs (nylon screw for electrical isolation)
• PCB mounting holes: standard 4.3mm clearance drill
• Phillips #2 screwdriver; do not overtighten — nylon threads strip more easily than metal

Package Contents

• 20× M4×8mm nylon Phillips pan head screws

Frequently Asked Questions

Q: What is the maximum torque for M4 nylon screws?

A: The recommended torque for M4 nylon screws is approximately 0.5–0.8 Nm. Do not exceed 1.0 Nm as nylon threads will strip. Tighten finger-tight plus approximately 1/4 turn with a screwdriver. If the screw feels tight before reaching the correct position, check for cross-threading.

Q: When should I use M4 nylon screws instead of M3?

A: Use M4 nylon screws when: (1) the PCB or panel specifies M4 mounting holes, (2) the PCB is heavier and requires greater clamping force, (3) you are using M4 nylon standoffs (M4×18/20/30/40mm), or (4) the application requires greater structural stability than M3 can provide while maintaining electrical isolation.

Q: Can nylon screws be used with metal nuts?

A: Yes. Nylon screws can be used with metal nuts (stainless steel, brass) when the non-conductive property is only required at the screw body (not the nut). However, if full electrical isolation is required at both the screw and nut, use nylon nuts as well.
