Features

Unbrako Button Socket Head Cap Screws are ideally suited for use in materials too thin to countersink and in non-critical loading applications. Under tightly controlled manufacturing processes, heads are forged for greater strength and full formed radius-root rolled threads assure close tolerances, maximum strength and superior fatigue resistance. Deep accurate sockets allow full tightening, and heat treated alloy steel ensures maximum strength without brittleness.

• Low head streamline design for a smooth, aesthetic appearance, ideally suited for use in materials too thin to countersink and in non-critical loading applications.
• Deep, accurate socket for maximum key engagement.
• Heat treatment in a controlled atmosphere for maximum uniform strength and surface integrity without brittleness or decarburisation.
