CNC turned hex lock nuts and bushings are precision fastening and positioning components machined from aluminum, brass or stainless steel bar stock. They lock shafts, clamp components and provide accurate axial location in assemblies that see vibration or repeated adjustment.
Each part is turned and milled in one setup: the hex body is machined for wrench engagement, the bore is held concentric to the hex within ±0.005 mm, and a saw slot or split-clamp feature is cut to create the locking action. Threads and internal steps are gauge-checked per lot so the nut seats cleanly and releases without damage to the shaft.
Finished with natural or black anodizing (aluminum), passivation (stainless) or nickel plating (brass), these components serve shaft collars, locking nuts, clamping bosses, robotics fasteners and optical mounts — from 100-piece prototypes to repeat production runs.
Hex wrench bodies turned and milled to DIN 936 tolerance. OD, hex flats and internal bore completed in one chucking for perfect concentricity and reliable tool engagement.
Live-tool milling cuts precise saw slots across the hub. The split clamp design creates radial compression for secure shaft mounting, eliminating separate set screws and lock rings.
Finish bored to +/-0.005mm in the final operation. Aluminum parts receive Type II hard anodizing; stainless parts passivated per ASTM A967. All finishes applied in-house.
From aerospace-grade aluminum to medical-certified engineering plastics, our in-house CNC machining centers work a broad range of metals and plastics under one roof.
