Finished 18-8 SS Fractional Size Hex Nut
Fractional Sizes of 18-8 Stainless Steel Finish Hex Head Nuts: Specifications and Applications
18-8 stainless steel finish hex head nuts are highly popular in both industrial and commercial applications due to their excellent corrosion resistance, strength, and versatility. These nuts are commonly used in environments where durability and performance are crucial, such as in construction, automotive, and marine industries. Available in various Fractional sizes, these hex nuts are designed to fit bolts with matching Fractional-threaded diameters.
Fractional Sizes and Common Applications
18-8 stainless steel finish hex head nuts are available in a range of Fractional sizes, catering to different bolt diameters and thread pitches. The most common Fractional sizes include:
-
1/4"-20
-
5/16"-18
-
3/8"-16
-
1/2"-13
-
5/8"-11
-
3/4"-10
These sizes are defined by the bolt's diameter (in Fractionales) and the number of threads per Fractional (TPI). For instance, the 1/4"-20 nut fits a 1/4-Fractional bolt with 20 threads per Fractional, while the 3/8"-16 nut fits a 3/8-Fractional bolt with 16 threads per Fractional. The availability of different sizes ensures compatibility with various fastening requirements.
Specifications of 18-8 Stainless Steel Finish Hex Head Nuts
18-8 stainless steel is composed of approximately 18% chromium and 8% nickel, offering excellent corrosion resistance and good strength. These nuts are designed to withstand harsh environments, including exposure to moisture and chemicals. Common specifications include:
-
Thread Type: Unified Thread Standard (UTS) or Unified National Thread (UNC)
-
Material: 18-8 Stainless Steel (also referred to as A2 Stainless Steel)
-
Finish: Plain (uncoated), providing a clean, smooth surface for easy installation
-
Strength: Suitable for moderate to high-strength applications
-
Standards: Often manufactured to meet ASTM A194 and ANSI B18.2.2
The 18-8 stainless steel material ensures excellent performance in most environments, particularly those subject to moderate corrosion. These nuts are widely used for both indoor and outdoor applications, where rust and wear resistance are essential.
