🔌 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
