Minimum hardware to get started:

• Machine Screws or Standoffs (M2 to M8) : to pass through the washers and physically secure your components.
• Precision Screwdriver : to carefully tighten the fasteners without applying excess torque that could crush the nylon.
• Target PCB or Chassis : the physical frame, development board, or sensor module you intend to mount safely.

Safety Warnings:

• Torque Limits: Nylon is softer than metal. Do not over-torque your screws, as this will crush the washer, deform its shape, and compromise the stability of the mount.
• Thermal Limits: Nylon can melt or deform at high temperatures. Do not use these washers in direct contact with 3D printer hotends, massive heatsinks, or high-temperature power components.

Included in the Box:

• 1,150× Assorted Black Nylon Washers with 15 sizes
• 1× 15-Compartment Snap-lock Organizer Box

Frequently Asked Question

• Are these nylon washers compatible with standard M3 brass standoffs?
  Yes, the kit includes multiple sizes specifically designed to slide perfectly over standard M3 machine screws and standoffs.
• Can I use these washers to mount a standard PC motherboard?
  Yes, the larger sizes in this kit are ideal for insulating motherboard mounts from the metal chassis.
• Are they compatible with carbon-fibre drone frames?
  Yes, they are highly recommended for drone builds to isolate the flight controller from the conductive carbon fibre frame.
• Can I use these washers near high-temperature components like 3D printer hotends?
  No, nylon is a thermoplastic and will soften or melt if placed in direct contact with high-temperature heating blocks or massive power-dissipating heatsinks.
• Are these nylon washers electrically conductive?
  No, black nylon is an excellent insulator and will not conduct electricity, making it perfect for PCB mounting.
• Can they be used to isolate high-voltage AC circuits?
  While nylon is an insulator, this kit is intended for low-voltage DC hobbyist and IoT electronics, not mains AC isolation.
• Do these washers provide electrostatic discharge (ESD) protection?
  They provide physical electrical isolation between layers, which prevents direct shorts, but they are not specialized anti-static (ESD-dissipative) components.
• Where exactly should the washer be placed during assembly?
  Place the washer directly between the metal screw head (or nut) and the surface of your printed circuit board.
• Do I need to use two washers per mounting hole?
  For maximum safety, using one on top (under the screw head) and one on the bottom (above the standoff) completely isolates the PCB from the metal fastener.
• Does this assortment box include the matching metal screws and nuts?
  No, this kit contains only the 1,150 insulating nylon washers; matching metal or nylon screws must be purchased separately.
• Are there 3D CAD models available for these washers for enclosure design?
  Since these follow standard metric washer dimensions, you can use any generic metric washer CAD file (M2 through M8) in standard libraries like Fusion360 or GrabCAD.
