OCR6 Ø6 mm Metric Cage Construction Rods

OCR6 silver cage rods are specified as 6 mm in diameter, with M3 threaded holes and millimeter lengths stated in each source sales option. Single-rod and four-rod options are listed. The source photographs show recessed end holes without projecting screws. There is no formal drawing or individual SKU photograph; model configurations are established by the sales records, without transferring L30J-M engineering data from another source.

Length and supply options

Single-rod lengths are 6, 12.5, 25, 38, 50, 75, 100, 150, 200, 250, 300, 450 and 600 mm. Packs of four are listed at 6, 12.5, 25, 38, 50, 75, 100, 150, 200 and 250 mm. All 23 sales records explicitly state 6 mm diameter, M3 threaded holes and the corresponding length; four-rod options also state rod count. Single-rod options are distinguished from the explicit four-packs. Confirm final packaging and accessories.

Threads and length datum

M3 is taken directly from the threaded-hole specification in the sales records, rather than inferred from model digits. The photographs show recessed end holes, but no drawing establishes identical internal features at both ends, hole depth, pitch, usable thread length or end-screw dimensions. Listed lengths are source sales specifications with no formal dimension datum; an exclusion for projecting screws is not added.

Assembly and compatibility

The main image identifies cage rods and a 6 mm diameter. Check mating holes, clamping method, M3 connections and required length before assembly. The source does not identify a specific cage spacing or compatibility with other brands, so universal 30/60 mm compatibility is not claimed. The photographs do not establish complete assembly contents. Cage plates, supports and optical components are not automatically supplied.

Material and performance limits

The photographs show silver cylindrical metal rods, without an explicit material grade or finish specification. The 303 stainless-steel claim from a different series is not transferred here. Diameter tolerances, straightness, loading, roughness and numerical accuracy are unspecified. Confirm those requirements, supplied screws and custom dimensions separately.
