It"s a block! It"s a ring! It"s the BX0X08DCB! These hefty blocks are double-counterbored for use with a #10 screw. The BX0X08DCB is counterbored on both sides, so it is reversible. A unique block that can be used for a wide range of applications where a strong attractive or replusive force is required. Great for easily attaching a very powerful magnet to a surface that it would not normally stick to.
This size is also available in grade N52 (no hole) as part number
