These aluminum hexagonal standoffs are great for mounting PCBs to your chassis or to separate multiple levels of decks in your robot. The body of each male-female standoff is 1-1/4" long by 3/16" wide. The male threads extend another 3/16" past the standoff body (dimension M on the mechanical drawing to the right) and the female threads go 3/16" to 1/4" into the body (dimension F). You can easily screw multiple units together to make longer standoffs. The threads are 4-40 on both ends.
These metal standoffs are available in different lengths and thread types.
