17-4 PH Torx Screws

17-4 PH Torx Screws

17-4 PH Torx 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 Torx screws yield strength is up over 4 times greater. When compared to Duplex 2205 screws, the yield strength of 17-4 PH can be up to 2-½ times greater.

17-4 Torx screws are available in 8 different aged (precipitation hardened) conditions offering a variety of mechanical properties.

17-4 PH Torx Screw Features and Benefits

17-4 PH Torx screws are characterized by a 6-point star-shaped pattern, also called a star drive, spined socket or hexalobular (ISO 10664). Where Phillips heads were designed to cause the driver to cam-out (prevent overtightening), Torx screws were designed resist cam-out. This feature allows 17-4 PH Torx screws to provide increased torque as well as better torque transfer between driver and fasteners. This feature also helps to reduce wear on driver bits.

17-4 PH Torx Screw Advantages

· Resistant to cam out (process by which a screwdriver slips out of the head)

· 17-4 PH Torx screws are more difficult to strip

· Increased tamper resistance as a star driver isn’t as common

· Driver insert is less susceptible to damage when over torqued than Allen head
