Threaded Tube M10
You can screw these threaded ends into the top of a lamp holder. Place a nut or strain relief with internal thread on top.
Note that the threaded tube is screwed in instead of the strain relief, but does not take over the task of the strain relief. The weight of the lamp is not evenly distributed at a threaded end.
Available in 6 sizes: 1.5 cm, 2 cm, 2.5 cm, 3 cm, 4 cm and 5 cm.
