What is jam nuts ?
It is a type of hexagon nut. The thickness is only half or less than that of a normal hexagonal nut, also called a thin hexagonal nut or Low Profile Thin Hex Nut
Types of jam nuts
T&Y jam nuts come in several types: ultra-thin, coarse thread, fine thread, and left-hand thread.
Our jam nuts are manufactured to high standards, ensuring durability, reliability, and excellent performance across a wide range of applications.
In some narrow environments, ordinary hex nuts are not easy to install. To solve this problem, special ultra-thin hex nuts have been designed, also known as plate nuts.

The coarse thread hex jam nut is specifically designed to be used in conjunction with coarse thread bolts, making it suitable for quick disassembly and assembly scenarios.
DIN 439 ISO 4035
Size: M2-M52
These are used with fine-threaded bolts for applications that require a precise and secure fit.
Fine-threaded jam nuts are often used in high-precision machinery and automotive applications.
Standard: DIN 936 ISO 8675 DIN 80705
Size: M2-M36

Designed for use with left-hand threaded bolts, these jam nuts are essential in applications where left-hand threads are needed to prevent loosening under rotational forces.
Standard: DIN 439/936 LH
