Size 1/2" x 1/2" x 1/2" This handy solid Brass cube can be used as a constructin block and a bearing for Standard Meccano Axles, because of it's thickness it is ideal to support a short Axle with just one bearing rather than a pair where space is tight
4.1mm centre hole for meccano axles and a threaded hole for fixing on the other 4 sides, these threaded holes can be meccano 5/32" threads or m4 metric threads, please choose option
