Hex Head Bolts 304 Stainless Steel M8x1.25 x 30mm

These are the longer M8 x 30mm bolts I used when converting my Husky workstations from two fixed wheels to four swivel casters. Once I added spacers to make up the height difference between the factory wheels and the new casters, the original bolts were no longer long enough.
 
These give you the extra length needed to mount the new casters with the spacers securely. I also have the exact spacers I used listed on the site if you’re doing the same workstation modification.
