Shop Huyett’s wide selection of jam nuts in multiple sizes, materials, and finishes to facilitate additional locking in your general-purpose applications. These fasteners pair with other jam nuts or hex nuts and connect to a wide range of bolts to enhance the holding power, especially in high-motion or vibratory environments 

Jam Nuts: Essential for Secure Fastening in Industrial Applications

Jam nuts are typically half as thick as standard hex nuts, allowing them to be used in situations where space is limited or where a low-profile nut is required. Their primary function is to "jam" or lock onto another nut, whether that is another jam nut or a hex nut, preventing loosening due to vibration or rotation. Jam nuts are available in various materials, including carbon steel and stainless steel, which offer durability and resistance to wear and tear.
Jam nuts serve a dual purpose: they provide a secure lock while also ensuring precise adjustments. This is particularly important in applications involving structural nuts or high-strength fasteners. By tightening a jam nut against a standard hex nut, it effectively locks the position, preventing any unwanted movement. They are versatile and can be used in conjunction with a range of bolt types, including structural bolts, to ensure a reliable and secure fastening solution.
  • Space Efficiency: In light-duty applications, jam nuts are ideal for tight spaces where standard nuts cannot fit.
  • Enhanced Security: Their primary function is to prevent loosening of nuts in high-vibration environments.
  • Precision Adjustment: The functionality allows for fine-tuning and securing of bolt positions.

Jam Nuts vs. Structural Jam Nuts

These two types of fasteners are identical in functionality – they both tighten against another jam nut or hex nut to lock it into place and resist vibration. However, structural jam nuts are designed for heavy-duty use in conjunction with structural bolts and hex nuts, while jam nuts are well suited for general-purpose applications and can be used with non-structural mating fasteners.
