What are M12X1.5 Fine x M12X1.25 Extra Fine Double Ended Metric Studs with a Dog Point?
These double ended metric studs feature M12X1.5 fine thread on one end and M12X1.25 extra fine thread on the other end, with an unthreaded center section and a short reduced-diameter cylindrical dog point.
The two different thread pitches allow a single stud to connect components with different M12 fine thread requirements while maintaining a common outside diameter. The dog point provides a lead-in feature that helps guide the mating hardware into alignment with the threaded end and can help protect the first full thread during assembly.
What material are these M12 Double Ended Metric Studs made from?
These studs are manufactured from hardened Class 10.9 high-strength steel with a plain, uncoated 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 leaves the steel uncoated and is commonly used for dry indoor applications, protected assemblies, or applications where corrosion protection is supplied separately.
Why choose M12X1.5 Fine x M12X1.25 Extra Fine Double Ended Studs with a Dog Point?
The primary advantage of this stud is the combination of two different M12 thread pitches in one fastener. The M12X1.5 fine thread provides one thread specification while the M12X1.25 extra fine thread provides a finer-pitch connection on the opposite end, making the stud useful for specialized assemblies where two different thread pitches are required.
Fine and extra fine threads also provide more threads per unit of length and finer adjustment compared with an M12 coarse thread. The dog point adds an assembly-friendly lead-in that helps align the mating nut or threaded component and can reduce the likelihood of damaging the first full thread during installation.
Where are M12X1.5 Fine x M12X1.25 Extra Fine Double Ended Metric Studs commonly used?
These specialized double ended studs are commonly used in automotive manufacturing, engines, transmissions, motorcycles, machinery, machine tools, industrial equipment, hydraulic equipment, pneumatic equipment, automation systems, robotics, fixtures, jigs, pumps, motors, gearboxes, brackets, housings, and mechanical assemblies.
They are particularly useful in automotive and OEM applications where different metric thread pitches are specified on opposite sides of a component or assembly, as well as for attaching covers, panels, brackets, mounting plates, manifolds, flanges, guards, and other removable components.
The dog point is beneficial in production and service applications where the mating hardware needs a guided lead-in for faster, more consistent thread engagement. These M12 fine and extra fine double ended studs are also useful for machine building, equipment repair, maintenance, fabrication, replacement parts, and specialized mechanical assemblies requiring two distinct M12 thread pitches in a single high-strength stud.
