MP159 Shoulder Bolts
As aerospace engineering advances, so must the materials to meet the technological requirements of this industry. Bolts made from MP159 have been developed to provide a solution to high temperature, high strength components. MP159 shoulder bolts offer strength capabilities similar to other Cobalt Alloys (MP35N) but can be used at much higher temperatures - up to 1100°F, compared to MP35N’s usable limit of 800F. In addition, MP159 bolts can be used beyond 1100°F in short term situations.

Waspaloy Flat Head Screws
Waspaloy flat head screws are known for their superb high strength at elevated temperatures. Waspaloy is a high performance nickel alloy combined with cobalt, chrome and molybdenum to create it’s unique combination of strength and high temperature stability.

Similar to that of Inconel 718 screws, Waspaloy flat head screws exceed the strength and stability of Inconel 718 at elevated temperatures beyond 1400°F. In addition, the oxidation resistance of Waspaloy screws make it an ideal materials for high temperature applications like gas turbines engines, and a variety of other aerospace components. -
Tungsten Button Head Cap Screws
Tungsten button head cap screws are known for their extreme high density; because of this unique attribute, they are often used for balancing rotating parts. Tungsten’s high mass also makes these screws radiopaque. This allows tungsten screws to block radiation and show up well on x-rays – even better than lead. Another unique attribute of tungsten is its extrmely high melting point of 3420°C. The high temperature stability of tungsten button head cap screws make them ideal for some of the hottest vacuum furnace environments. Beyond their high mass and temperature stability, tungsten fasteners are also very corrosion resistant.

Tungsten fasteners are usually made from tungsten alloys per ASTM B777, and range from 90% to 97% pure tungsten, alloyed with nickel and copper or nickel and iron. -
Alloy 20 Hex Bolts
Also known as Carpenter 20 and 20CB-3, Alloy 20 hex head bolts offer users a combination of nickel, chromium, molybdenum, and copper which provides good general corrosion resistance. Alloy 20 hex head bolts are best suited for mid-range corrosion use – better than steel alloys but not at the level of high performance nickel based alloys like Hastelloy C276. Alloy 20 is a nickel alloy that was specifically designed to withstand the harsh environment of hot sulfuric acid but also performs well in a variety of other acids. Alloy 20 hex head bolts are an ideal choice when you don’t need the corrosion resistance power and price-tag of high performance nickel alloys like Hastelloy C276; but you need something that will give you more protection than 316 stainless steel or even a Super Duplex 2507 stainless steel.

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). -
