What are Even Thread Double End Metric Studs, Class 10.9 Hardened Steel?
Even thread double end metric studs are threaded studs with equal-length metric threads on both ends separated by an unthreaded center section.
Because both threaded portions are the same length, the stud can be installed from either end while providing an equal amount of exposed thread for securing a nut or other threaded component. These studs are useful when a symmetrical threaded connection is preferred or when consistent installation dimensions are important.
These are special articles that vary dimensionally from the DIN and ISO dimensional standards for double ended studs, including standards such as DIN 938 and DIN 939.
What material and finishes are available for these Even Thread Double End Metric Studs?
These studs are manufactured from hardened Class 10.9 high-strength steel and are available with a plain, zinc plated, or yellow zinc plated finish. Class 10.9 steel provides high tensile strength and is well suited for demanding mechanical fastening applications where greater strength is required.
The plain finish is suitable for dry indoor or protected applications, while zinc plating provides corrosion resistance for general-purpose applications and yellow zinc plating provides additional corrosion protection with a distinctive gold-yellow appearance.
Why choose Even Thread Class 10.9 Double End Metric Studs?
The even thread design provides equal thread engagement on both ends, making these studs particularly useful for symmetrical assemblies and applications where consistent installation depth and exposed thread are desired. The double ended configuration creates a strong threaded connection while allowing the attached component to be secured with a metric nut.
The hardened Class 10.9 steel construction provides high mechanical strength, while the choice of plain, zinc plated, or yellow zinc plated finish allows the stud to be matched to the environmental and corrosion-resistance requirements of the application.
Where are Even Thread Double End Metric Studs commonly used?
Class 10.9 hardened steel even thread double end metric studs are commonly used in machinery, automotive components, motorcycles, engines, transmissions, industrial equipment, machine tools, fixtures, jigs, automation equipment, robotics, pumps, motors, gearboxes, brackets, housings, and general mechanical assemblies.
They are particularly useful for attaching covers, panels, brackets, mounting plates, guards, manifolds, flanges, and other removable components where equal thread lengths are beneficial. These metric studs are also used in OEM manufacturing, machine building, equipment repair, maintenance, fabrication, and replacement applications where a high-strength, symmetrical threaded stud is required.
