MP35N Socket Head Cap Screws
MP35N socket head cap screws are known for their extraordinary strength and are the strongest screws we offer at RAYCHIN. MP35N socket head cap screws 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 socket head cap screws, they are also exhibit good corrosion resistance and can resist most mineral acids, hydrogen sulfide, seawater and salt spray environments. MP35N socket head cap screws are also resistant to high temperature oxidation and could operate in environments up to 800°F and still maintain much of its strength.

17-4 PH Socket Head Cap Screws
17-4 PH socket head cap screws are made from a precipitation hardened stainless steel most known for its exceptional strength and its ability to maintain its mechanical properties to 600°F. Compared to 316 stainless steel, 17-4 PH socket head cap screws yield strength is up over 4 times greater. When compared to Duplex 2205 socket head cap screws, the yield strength of 17-4 PH can be up to 2-½ times greater. 17-4 socket head cap screws are available in 8 different aged (precipitation hardened) conditions offering a variety of mechanical properties.

Titanium Socket Head Cap Screws
Titanium fasteners are best known for being strong, lightweight, and corrosion resistant. They are critical to many industries including chlor alkali, marine, off-shore oil & gas, desalination, medical, and pulp and paper. Grade 2 and 5 are the most commonly used grades of titanium screws: • Grade 2 (UNS R50400 / 3.7035) :Commercially pure titanium and the most common grade for screws. • Grade 5 (UNS R56400 / 3.7165): Superior strength-to-weight ratio for a unique combination of corrosion and high strength.

Monel Socket Head Cap Screws
Monel® socket head cap screws, 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 socket head cap screws 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 socket head cap screws are perhaps the most resistant of all commonly used specialty alloys.

A286 Socket Head Cap Screws
A286 socket head cap screws, also known as Alloy 660 screws are stainless steel alloy which contains iron, nickel and chromium. A286 screws are known for their high strength, creep resistance and oxidation resistance at elevated temperatures once age hardened. As a result, A286 / Alloy 660 screws provide high levels of strength from room temperature up to about 1300°F (700°C). A286 socket head cap screws are also mildly corrosion resistant. While they should not be used for strong acid environments, they provide excellent oxidation resistance up to 1500°F (815°C) in conditions that would typically be found in high temperature exhaust streams.

MP159 Socket Head Cap Screws
As aerospace engineering advances, so must the materials to meet the technological requirements of this industry. Screws made from MP159 have been developed to provide a solution to high temperature, high strength components. MP159 socket head cap screws 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 screws can be used beyond 1100°F in short term situations.

Tungsten Socket Head Cap Screws
Tungsten socket 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 fasteners 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 socket 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 socket head cap screws 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.
