L30J Ø6 mm 303 Stainless Steel Cage Construction Rods

L30J-M stainless-steel cage rods have a 6 mm outside diameter and an M3 threaded hole at each end. The source identifies them for 30 and 60 mm cage systems. Single rods and packs of four are offered in model-specific lengths. The stated material is 303 stainless steel. Body length L excludes the screws projecting from the ends.

Length and pack options

Single-rod options are 6, 10, 12.5, 25, 38, 50, 75, 100, 150, 200, 250, 300, 400, 450 and 600 mm. Four-rod packs cover the same lengths except 10 and 400 mm. All 27 individual model cards were checked. The M10 card states 10 mm, although that model is absent from the engineering table. M400 has no individual SKU photograph; its 400 mm length is established by the table. M6 and M10 in the model names do not specify end threads.

End connections

Each end has an M3 threaded hole for a removable screw. The drawing calls out M3 screws in two places, and its L dimension covers only the cylindrical body, excluding projecting screws. The source advertises two supplied M3 screws, without establishing the total screw quantity in a four-rod pack. Confirm supplied hardware. Thread pitch, hole depth, screw projection and tightening torque are unspecified.

Material and assembly

The source identifies 303 stainless steel with a smooth surface. These rods join compatible components in 30 or 60 mm cage assemblies; check both 6 mm rod-hole fit and M3 connections. The main photograph describes the series application, while the drawing identifies the end connection. Verify specific 60 mm hardware and compatibility with other brands. Cage plates, supports and optical components are not automatically included.

Selection limits

Check length datum, rod count and threads before assessing clearance and mating parts. Custom lengths are advertised, but diameter tolerances, straightness, surface roughness, loading and numerical accuracy are not provided. A smooth appearance does not establish these specifications. Light gray, white and off-white in three sales options are source category labels; the cards show silver metal rods and do not establish distinct coatings.
