Double-End Stud DIN 939
Double-threaded stud with plain center shank for stud connections.
Manufacturing Scope
Double-End Stud DIN 939 is a Fasteners family precision-turned on a Goodway SW-20, covering 11 variants — diameters ⌀4–12 mm, lengths 30–94 mm, standard material Steel (also steel, stainless, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request an instant quote with the code you need.
The family is machined from ⌀12 mm bar stock; its longest variant is BAGA-939-10 at 94 mm. Besides turning, the family requires thread turning (6 sizes from M4 to M12). All of it is completed in a single setup, without the part leaving the machine.
The most slender variant is BAGA-939-06: 63 mm long at ⌀6 mm, a length-to-diameter ratio of 10.5. This ratio is the very reason sliding-head lathes exist. The guide bushing supports the bar immediately beside the cutting point, so there is no deflection; the same part chatters and drifts in diameter on a conventional lathe.
Variants are machined to 6g tolerance; the smallest is BAGA-939-01 (⌀4 mm) and the largest BAGA-939-11 (⌀12 mm). The family includes threaded, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
