Thin Nuts

A thin nut, also commonly known as a jam nut, is a low-profile hex nut with a significantly reduced height compared to a standard nut. Its primary functions are to serve as a secondary locking nut in a double-nut system, prevent thread wear, or provide fastening in applications with strict axial space constraints.

Product details

Typical Applications:

Locking & Vibration Resistance: Used as a jam nut tightened against a primary nut to mechanically lock it in position, preventing loosening under vibration in automotive and machinery assemblies.
Space-Constrained Assemblies: Essential in compact designs such as precision instruments, consumer electronics, and tight-tolerance equipment where standard nut height is prohibitive.
Thread Protection & Spacing: Often employed to protect exposed threads from damage or to act as a spacer or adjustable stop on a threaded rod or shaft.

Our Product & Custom Capabilities:
We supply thin nuts in a variety of materials and finishes to meet diverse application needs. Our customization options include:

Material & Grade: Carbon steel (Grade 5, 8), alloy steel, and corrosion-resistant stainless steel (A2-70, A4-80).
Dimensional Precision: Custom internal threading (metric or imperial), precise reduced heights, and specific width across flats to fit specialized tools or spaces.
Surface Treatment: Zinc plating, hot-dip galvanizing, or passivation to provide required corrosion protection and appearance.

Our thin nuts offer a reliable and engineered solution for secure fastening in limited spaces, effective vibration resistance, and enhanced assembly versatility.
