Understanding the Basics of 1 3/16 x 24 Threads
1 3/16 x 24 threads are part of the Unified Thread Standard (UTS). The major diameter of 1 3/16 inches (or 1.1875 inches) is significant for various applications, with the “24” indicating that there are 24 threads per inch. This thread specification is commonly used in both coarse and fine threading contexts.
Thread Types Explained
- Unified Coarse (UNC): Designed for general applications where quick assembly is crucial. It offers better strength and is easier to assemble.
- Unified Fine (UNF): Provides greater tensile strength and is ideal for applications requiring precision and tighter tolerances.
- Unified Extra Fine (UNEF): Utilized in specialized applications that demand even finer adjustments and high precision.
- National Pipe Thread (NPT): Primarily used for connecting pipes and fittings, allowing for fluid-tight seals.
Applications of 1 3/16 x 24 Threads
Applications for 1 3/16 x 24 threads vary significantly, depending on the type and industry.
Automotive and Heavy Machinery
In automotive and heavy machinery, UNC threads are often preferred. These threads offer a robust solution for fastening components that experience high levels of stress, as seen in engines and suspension systems.
Aerospace and Defense
UNF threads are commonly used in the aerospace industry due to their precision. They are ideal for components that must withstand extreme conditions while maintaining accuracy and performance.
Plumbing and HVAC
NPT threads are essential in plumbing and HVAC systems. Their design allows for secure connections that prevent leaks, ensuring safety and efficiency in fluid and gas transport.

FAQ
What is the significance of “24” in 1 3/16 x 24 threads?
The “24” indicates the number of threads per inch. A higher number means finer threads, which can lead to better holding power but may require more precise alignment.
What materials are commonly used for 1 3/16 x 24 threads?
Common materials include steel, aluminum, stainless steel, and brass, depending on the application’s strength, corrosion resistance, and weight requirements.
How do I determine which thread type to use?
Consider the application, required strength, and precision level. For general use, UNC is sufficient, while for precision applications, UNF or UNEF is more appropriate.
Can I use UNC threads in place of UNF threads?
While it’s possible, it’s not recommended due to differences in strength and fit. Always use the specified thread type for optimal performance.
What is the difference between a bolt and a screw regarding threading?
Bolts are typically used with nuts and have a thicker shaft, while screws are designed to be threaded directly into material. Both can utilize 1 3/16 x 24 threads.
Are 1 3/16 x 24 threads compatible with other sizes?
No, 1 3/16 x 24 threads are specific to that diameter and thread count. Mixing different sizes can lead to improper fit and failure.
What tools are needed to work with 1 3/16 x 24 threads?
Standard tools include taps and dies for cutting threads, wrenches for fastening, and calipers for measuring dimensions.
How do I measure the pitch of a thread?
The pitch can be measured by counting the number of threads in a specific length, typically one inch, or using a thread pitch gauge.
Are there industry standards for 1 3/16 x 24 threads?
Yes, they follow the Unified Thread Standard (UTS), which provides guidelines for dimensions, tolerances, and applications.
What should I consider when selecting a thread for high-stress applications?
Consider the load capacity, material strength, and environmental conditions. Use UNC for general purposes and UNF for high-precision applications to ensure reliability.
