Plastic Thumb Nuts

In stock

Thumb Nuts are a type of nut with a knurled outside diameter (surface). This design facilitates manual tightening by hand, and also secures the nut into a handle or cover. They are typically used in applications where the fasteners will be removed regularly.

Made from Natural Nylon 6/6, a strong, tough and durable material that is ideal for connecting elements and other technical components. It has self-lubricating properties, and is resistant to moisture, vapour and salt water. Our range features slotted and non slotted options.

  • Quick and easy
  • Tool-free installation and removal
  • Flame resistance rating is UL94 V2.
