Nylon Insert Nuts – Thin Type FAQs

What is a thin type nylon insert nut?

A thin type nylon insert nut is a low‑profile hexagonal nut fitted with a nylon locking insert. Compared to a standard nylon insert (nyloc) nut, it has a reduced height, making it suitable for applications where space is limited while still providing resistance to loosening.

How do thin type nylon insert nuts work?

The nylon insert deforms around the threads of the bolt during installation, creating prevailing torque that helps prevent the nut from loosening under vibration.
The thinner nut body allows use in restricted spaces, while the nylon insert provides the locking function.

When are thin type nylon insert nuts typically used?

Thin type nylon insert nuts are commonly used:

  • Where axial space is limited and a standard nyloc nut is too tall
  • In applications subject to vibration or movement
  • Where a self‑locking nut is required without additional locking devices
  • In light to medium‑duty mechanical assemblies

They are often selected as an alternative to standard nylon insert nuts where clearance is restricted.

Are thin type nylon insert nuts suitable as a primary fastening nut?

Due to their reduced height, thin type nylon insert nuts are not generally recommended as the sole primary fastening nut in higher load applications. They are best suited for space‑restricted assemblies where loading is moderate and vibration resistance is required.

Can thin type nylon insert nuts be reused?

Thin type nylon insert nuts may be reused, provided the nylon insert still offers sufficient resistance to rotation. As with all nylon insert nuts, repeated use will reduce the effectiveness of the locking insert, and the nut should be replaced if the prevailing torque is reduced.

Are thin type nylon insert nuts suitable for high‑temperature applications?

No. Thin type nylon insert nuts are not suitable for high‑temperature applications where the nylon insert could soften or degrade. Alternative locking solutions should be used in elevated‑temperature environments.

What thread types do you supply?

We supply thin type nylon insert nuts in inch thread sizes only.
These nuts must be matched with the correct inch‑threaded bolts or studs.

What materials are available?

Our range of thin type nylon insert nuts is available in:

  • Stainless steel A2
  • Stainless steel A4

Are thin type nylon insert nuts known by any other names?

Thin type nylon insert nuts may also be referred to as:

  • Thin nyloc nuts
  • Low‑profile nylon insert nuts
  • Thin nylon lock nuts

All describe the same low‑height nut design with a nylon locking insert.

How do I choose the correct thin type nylon insert nut?

When selecting a thin type nylon insert nut, consider:

  • Correct inch thread size to match the mating fastener
  • Available space, ensuring a thin profile is required
  • Application load, noting the reduced nut height
  • Operating temperature, ensuring suitability for a nylon insert
  • Material selection (A2 or A4) based on corrosion resistance needs
