Product Description
7/16″ UNF A2 Stainless Steel Hexagon Head Bolts With Shank
Part-threaded 7/16″ UNF hexagon head bolts manufactured from corrosion-resistant A2 stainless steel. These imperial bolts have an unthreaded shank between the head and threaded section, making them suitable for assemblies where a plain bearing surface is required through the joined components.
- Thread size: 7/16″-20 UNF
- Thread pitch: 20 threads per inch (TPI)
- Material: A2 stainless steel
- Head style: Hexagon head
- Thread form: Unified National Fine (UNF)
- Drive size: 5/8″ AF spanner or socket
- Construction: Part threaded with an unthreaded shank
- Available lengths: 1 3/4″ to 6″
The fine 20 TPI thread provides controlled adjustment and good clamping performance. These bolts must be used with matching 7/16″-20 UNF threaded components. They are not compatible with 7/16″-14 UNC, BSF or metric nuts.
A2 Stainless Steel
A2 stainless steel offers good resistance to corrosion in many indoor, outdoor and general engineering applications. For marine environments or regular exposure to salt and chlorides, A4 stainless steel will usually provide better corrosion resistance.
Stainless steel threads can gall during assembly. Clean threads, suitable lubrication and controlled installation speeds can help reduce this risk.
