## 🔌 Function

A hexagon screw is a threaded fastener that clamps two or more engine components together at a specified torque. The 95 mm length suits joints requiring that specific grip depth, and the hex head allows tightening with a standard socket or spanner.

## ⚠️ Common Signs of Failure

-   Rounded, damaged or corroded hex head preventing proper socket engagement
-   Stripped, galled or seized threads that will not hold torque
-   Stretched or necked shank after over-torquing, causing loss of clamp load
-   Repeated loosening of the joint, or fluid, oil or exhaust leakage at the fastened flange
-   Visible rust, pitting or cracking from corrosion in the marine environment

## 🛠️ Service Notes

-   Check the length, thread and strength grade of the replacement against the screw you removed — engine fasteners are chosen for a specific clamp load, and a longer or softer screw is not a substitute
-   Clean the threads in the component and make sure the mating faces are clean and flat before assembly; dirt, paint or old sealant in a joint feels like tightness and leaves the joint loose
-   Tighten to the torque figure and the tightening sequence given in the workshop manual for your engine, working up progressively rather than pulling each screw down in one go
-   Use thread locking or sealing compound only where the manual calls for it, and renew the locking washer, tab washer or nut that works with the screw
-   Renew rather than reuse screws that are corroded, thread-damaged or visibly stretched, and any screw the manual tightens by torque-plus-angle
