Hobson Cup Head Bolt & Nut, M6 / 100

The Hobson cup head bolt & nut is a domed-head bolt supplied with its nut, in class 4.6 UTS with a hot dip galvanised finish. A cup head bolt has a smooth domed head with no drive, so it is tightened from the nut end. Cup head bolts are normally made with a square section under the head that holds the bolt in place while the nut turns.

Class 4.6 is low tensile carbon steel, and corresponds to imperial grade 2. These bolts are Class 4.6 UTS. UTS is a tensile strength abbreviation. Pack quantity changes with size and length and is shown for each item.
