Stainless Steel hex head flange screw FT UNC 3/8 "-16 x 1-1/4 ", Plain Finish

1. Description:

 

     Hex flange bolts are used on vehicle frames, especially truck frames, and anywhere a hex washer head bolt is needed. The large bearing surface distributes clamping force over a large area, allowing them to be used with irregular and oversized holes. Hex flange bolts are often used with Grade G Flange Style Lock Nuts to create a bolt/nut system that resists loosening and spans a wide area. They are also known as:hex frame flange bolts, hex washer frame bolts, hex flange screws.Serrated hex flange bolts have teeth under their head that grip the mating surface to resist loosening. 12 point flange bolts, also called

counterbore cap screws, are used in aircraft and aftermarket automotive applications because they are easily installed using a 12 point socket and pneumatic impact wrench, while motorcycle enthusiasts like the small, externally wrenched decorative head.

 

      Threads are standard right-hand. Hex and 12 point are available in Unified inch coarse series (UNC, Unified National Coarse) and Unified inch fine (UNF, Unified National Fine); serrated hex in Unified inch coarse. Flange bolts are partially and fully threaded depending on size and length. The point for hex types is chamfered or rounded; for 12 point, it's flat and chamfered.

 

      Hexagon flange bolts are the industry standard for fasteners with forged heads. Provides same holding power as a washer. A bolts and several other common specifications require a standard finished hex head. The most common hexagonal hex bolts are zinc plated and the stainless steel hex flange bolts is the choice which no need to coating to read corrosion resistance, and so as to the carbon steel which go through the heat treatment to achived the higher grade and hight tensile. and the serrated flange keep the fastening from sliding while in high vibration.

3. Applications:

 

    Flange bolts distribute the clamping load across the fastening surface. The teeth acts as a mean to distributing the clamping load of the bolt across the fastening surface. A flange bolt is designed to provide the same holding power as a washer. General Fastening applications where need high strength and superior corrosion resistance. Typical applications Construction, Machine repairs outdoor. Designed for using in high-stress and high-strength applications. Black Grade 8.8 offers corrosion resistance and protection and high tensile. In many industry constructure etc. applications.
