Tantalum Hex Cap Screws

Tantalum hex head cap screws are best known for its unmatched corrosion resistance and chemical inertness. Tantalum screws have a similar corrosion resistance to that of glass, but all of the typical mechanical and electrical properties of a metal. Tantalum screws are also extremely stable at high temperatures, since tantalum has a melting point around 3000°C. High temperature applications require vaccum or inert gas since tantalum may embrittle when used in oxygen rich environments above 250°C. Tantalum hex head cap screws are also one of the most bio-compatible metals available and is also radio-opaque due to its high density (16.68 g/cm3). All tantalum hex head cap screws are available in commercially pure tantalum and tantalum 2.5% tungsten (Ta-2.5%W).
