Alloy Steel Socket Cap Screw, Zinc Plated Finish, Internal Hex Drive, Meets DIN 912, 16mm Length, Fully Threaded, M6-1 Metric Coarse Threads (Pack of 100)

Metric socket head cap screws, also known as Allen head screws, have a recessed drive and are commonly used when there is not enough clearance for a conventional wrench or socket. They are durable and used in many industrial applications.Zinc plating helps prevent corrosion. Alloy steel is steel that has been alloyed with other materials to improve overall physical properties. Steels are designated by a four-number SAE steel grade. The first two digits indicate the primary materials used to form the steel. The last two digits identify the percentage of carbon for the alloy (in hundredths). Tensile strength ranges for the alloys typically used in these fasteners range from 170,000 to 180,000 psi (pounds per square inch), making these among the strongest of materials.With a high cylindrical head, socket head cap fasteners offer high holding power at high torque levels. Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits.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.

• Zinc plating is suitable where strength and corrosion resistance are primary considerations
• Alloy steel is one of the strongest materials used in fasteners, making this an ideal material to use when the primary concern is the application pulling apart
• Socket cap head offers high holding power
• Hex socket is driven by hex wrenches or power tools with hexagonal bits
