How to print only the hex values from hexdump without the line numbers or the ASCII table? [duplicate]

Using xxd is better for this job:

xxd -p -l 50 -seek 10 file.bin

From man xxd:

xxd - make a hexdump or do the reverse.

    -p | -ps | -postscript | -plain
        output in postscript continuous hexdump style. Also known as plain hexdump style.

    -l len | -len len
        stop after writing <len> octets.
 
    -seek offset
        When used after -r: revert with <offset> added to file positions found in hexdump.
