Cylindrical Spacer with Knurled Hex Standoff and Short External Male Thread

Knurl od and external male thread length are inspected per your drawing requirements during initial part approval on every knurled hex standoff. Welltop's Dongguan CNC turning line produces these under ISO 9001 process controls. Knurl OD determines torque retention when press-fitted into a PCB hole; thread length governs how far the mating fastener can engage. The plant occupies circa 4,000 m², active in automotive, medical equipment, and oil & gas. Both are logged in the production record before dispatch. The cylindrical standoff body and knurled hex profile are produced from your latest drawing release; thread class and knurl pattern are verified against your callout during in-process sampling. Applications include consumer electronics PCB stacking, aerospace avionics board assemblies, drone flight controller mounts, and OEM instrument board fixings. Surface finish follows your drawing specification. Attach your print specifying ; our Dongguan team will return a quotation and lead time.
