Super Duplex Dog Point Socket Set Screws
M16 x 35 dog point socket set screws manufactured from Super Duplex stainless steel grade UNS S32760.
These premium-grade set screws have been manufactured for an industry requiring uncompromising performance in aggressive operating conditions.
Material Science That Delivers
Super Duplex stainless steel UNS S32760 stands at the pinnacle of corrosion-resistant alloys available for critical fastening applications. This advanced material combines an approximately equal balance of austenitic and ferritic microstructures. Delivering mechanical properties and corrosion resistance that substantially exceed conventional stainless steel grades including 316 and duplex 2205.
The alloy composition typically includes 25% chromium, 7% nickel, 3.5% molybdenum. Alongside additions of copper, tungsten and nitrogen. This carefully balanced chemistry creates a material with exceptional resistance to pitting, crevice corrosion, stress corrosion cracking and general corrosion across a remarkably broad range of aggressive media.
Super Duplex 32760 demonstrates outstanding performance when exposed to chlorides, making it the material of choice for seawater applications, offshore platforms, desalination plants and coastal installations. The alloy maintains structural integrity in acidic environments including sulphuric, phosphoric and organic acids commonly encountered in chemical processing facilities. Furthermore, it offers reliable performance across extreme temperature ranges, from sub-zero conditions to elevated operating temperatures exceeding 250°C.
The mechanical strength of UNS S32760 significantly surpasses austenitic stainless steels, with yield strength approximately double that of grade 316. This superior strength-to-weight ratio enables designers to specify smaller fastener dimensions whilst maintaining structural integrity. Reducing overall assembly weight and potentially lowering material costs despite the premium nature of the alloy.
Dog Point Design
The dog point configuration features a cylindrical extension on the fastener’s end, typically with a diameter slightly smaller than the set screw body. This design element serves multiple essential functions in precision engineering and manufacturing applications.
The cylindrical point locates precisely within drilled holes or recesses in mating components, preventing lateral movement whilst distributing contact stress over a larger surface area compared to cone or cup point alternatives. This characteristic is particularly valuable in jig and fixture work, where repeatability and accuracy directly impact manufacturing quality and productivity.
Our M16 x 35 dog point socket set screws in Super Duplex UNS S32760 serve various industries operating in the world’s most challenging environments. When component positioning, corrosion resistance and mechanical strength cannot be compromised, these fasteners deliver the performance reliability that engineers demand.
