Inconel Shoulder Bolts
Inconel® shoulder bolts, like Inconel 600, 601,625,686,718 & 725 bolts, are a family of nickel-chromium-molybdenum alloys used for their high strength at elevated temperatures and good corrosion resistance. Because of its high thermal stability, Inconel can be used in service temperatures ranging from cryogenic to 2200°F (982°C). The high alloy content of Inconel bolts enable it to withstand a wide variety of severe corrosive environments. In mild environments, such as the atmosphere, sea water, neutral salts, and alkaline media, there is almost no attack to Inconel bolts shoulder. In more severe corrosive environments the combination of nickel and chromium provides resistance to oxidizing chemicals, whereas the high nickel and molybdenum contents supply resistance to nonoxidizing environments.

Alloy 330 Shoulder Bolts
Alloy 330 shoulder bolts are specifically designed for high temperature furnace applications such as vacuum furnaces, heat treating and brazing applications. The most prized trait of alloy 330 is its ability perform under cyclic conditions of temperature extremes from heating and cooling; as well as in alternate carburizing and oxidizing atmospheres. An austenitic nickel-chromium-iron-silicon alloy, 330 shoulder bolts also offer industry a low coefficient of expansion, excellent ductility, and high strength.

Nitronic Shoulder Bolts
Nitronic is a high strength austenitic steel alloy that was designed for high temperature use. It offers good high temperature properties as well as good low-temperature impact resistance. In addition, Nitronic bolts also offer nearly double the yield strength of 300 series stainless steel. Nitronic fasteners are available in two alloy variations, Nitronic 50 and Nitronic 60, each offering different niche capabilities.

Monel Shoulder Bolts
Monel® shoulder bolts, like Monel 400 and K500, are made from a nickel-copper alloy and exhibit high strength, toughness and good corrosion resistance over a wide temperature range. An outstanding characteristic of Monel bolts is that they offer exceptional resistance to hydrofluoric acid, a particularly tough acid to deal with, in all concentrations up to the boiling point. For hydrofluoric acid applications Monel shoulder bolts are perhaps the most resistant of all commonly used specialty alloys. Monel alloy 400 & K500 bolts also exhibit excellent corrosion resistance in marine applications and have reasonable corrosion resistance to sulfuric and hydrochloric acids under reducing conditions. Because of these characteristics, Monel shoulder bolts are often found in marine and chemical processing applications.

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.

Tungsten Shoulder Bolts
Tungsten shoulder bolts 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 bolts radiopaque. This allows tungsten bolts 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 shoulder bolts 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 shoulder bolts 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.

Tantalum Shoulder Bolts
Tantalum shoulder bolts are best known for its unmatched corrosion resistance and chemical inertness. Tantalum bolts have a similar corrosion resistance to that of glass, but all of the typical mechanical and electrical properties of a metal. Tantalum shoulder bolts 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 bolts 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 shoulder bolts are available in commercially pure tantalum and tantalum 2.5% tungsten (Ta-2.5%W).

MP35N Shoulder Bolts
MP35N shoulder bolts are known for their extraordinary strength and are the strongest bolts we offer at Extreme Bolt. MP35N bolts owe their extraordinary strength to a unique alloy combination of nickel, cobalt, chrome and molybdenum and have ultimate tensile strengths that range from 227 ksi to 294 ksi (with age hardening). Beyond the strength of MP35N shoulder bolts, they are also exhibit good corrosion resistance and can resist most mineral acids, hydrogen sulfide, seawater and salt spray environments. MP35N bolts are also resistant to high temperature oxidation and could operate in environments up to 800°F and still maintain much of its strength.
