Manufacturing Scope
Socket Head Cap Screw DIN 912 is a Fasteners family precision-turned on a Goodway SW-20, covering 11 variants — diameters ⌀4.5–18 mm, lengths 14–65 mm, standard material Steel (also stainless steel, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request a quote with the code you need.
The family is machined from ⌀18 mm bar stock; its longest variant is BAGA-912-10 at 65 mm. Besides turning, the family requires thread turning (8 sizes from M2.5 to M12). All of it is completed in a single setup, without the part leaving the machine.
The variant with the highest length-to-diameter ratio is BAGA-912-06: 41 mm long at ⌀10 mm, L/D 4.1. This ratio is achievable on a conventional lathe as well; the sliding-head advantage in series work is that the part never leaves the machine, so the size does not drift from variant to variant.
Variants are machined to 6g tolerance; the smallest is BAGA-912-01 (⌀4.5 mm) and the largest BAGA-912-11 (⌀18 mm). The family includes threaded, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
