Can I use these bolts for front derailleur shifters?

What is the material of these fixing bolts?
Genuine Shimano parts are typically made from durable steel or high-grade alloys designed for bicycle components.
Where can I find the torque specification for these bolts?
Torque specifications are usually found in the official Shimano service manual for the SL-M770 shifter. If not explicitly stated, tighten them firmly but do not overtighten.
Troubleshooting
Shifter feels loose or sloppy
Check if the SL fixing bolts are securely tightened. If they are, the cable may need adjustment or the shifter mechanism might have internal wear.
Difficulty installing the bolt
Ensure you are using the correct M4 size tool and that the bolt threads align properly with the shifter's threaded hole. Clean any debris from the threads.
Shifting is inconsistent after replacement
Confirm the correct bolt was used and securely fastened. Re-adjust your derailleur cable tension and indexing according to Shimano's guidelines for the SL-M770 shifters.
