18-8 Stainless Steel Set Screw, Plain Finish, Hex Socket Drive, Cone Point, Meets ASME B18.3/ASTM F880, 3/16" Length, #8-32 UNC Threads, Imported (Pack of 100)

Set screws are often used for holding a pulley, gear, or other parts from turning relative to a shaft.Stainless steels are used for their corrosion resistance, high-temperature strength, scaling resistance, and low-temperature toughness. These properties account for their wide use in practically every industry. Austenitic stainless steels are alloys of iron and carbon that contain between 16% and 30% chromium, a maximum of 0.15% carbon, along with nickel (or manganese), and other alloying elements. The chromium, which helps develop a passive surface oxide film, provides corrosion resistance. The 18-8 material name designates the amount of chromium and nickel in the material (18% chromium and 8% nickel).Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits. Good for permanent setting of parts, the sharp cone point penetrates deep into the surface to lock in place.A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine.

• 18-8 stainless steel includes 18% chromium and 8% nickel for corrosion resistance
• Stainless steel is suitable where formability and cost are important considerations
• Hex socket is driven by hex wrenches or power tools with hexagonal bits
• Does not have an external head
