Thank you for offering this replacement part. My nice 12" combination square fell onto the floor which caused this bolt to break. I was able to easily replace it to keep using my square.

I have had my combination square over 30 years and it is still in fairly good shape. I used after market lock bolts to replaced the original and it was no longer useable for laying out lines for structural steel. Recently bought new ones from PEC tools and although they work better it is still not perfect to my liking. Still, the tool is in remarkable shape for using it regularly.
