Alamo Toolworks is proud to offer brass saw screws with split nuts in three sizes plus medallions.  
These screws are designed to be flush-mounted in the saw handle.  The under-head bolster is round, as manufactured.  These are easily squared using a file or if you're not comfortable doing that yourself I'll do it for you for an additional charge of $1.00 per screw.  If you do want me to square the bolster please send me a message before purchasing and I will invoice you for the corrected price. 
Screws can be returned within 14 days of receipt only if they are completely un-modified and have not been installed.  If you square the bolster or install the screw in a saw no returns allowed. 
Full installation instructions will be provided with purchase.  Briefly, you will need an appropriate size piloted counterbore and a drill press to perform a clean installation.  I also strongly recommend that the hole in your saw handle / tote and the hole in your saw plate / blade be reamed to fit the un-threaded section of the screw shank.
Quantity discounts available for purchases of 5 or more screws.  Contact me for bulk discounts.

Item Includes: 1 large size brass screw and 1 nut
