💡 How do you properly torque button head hex socket cap screws for high load applications?
- Select the correct allen wrench size matching 1.5mm drive width to prevent stripping threads
- Apply threadlocker on alloy steel bolts before inserting into aluminum or steel substrates
- Use a calibrated torque spanner rated for M2.5 threaded fasteners under heavy vibration
- Back off roughly ten percent after initial seating to allow metal fatigue compression during run-in periods
