• Officially catalogued in the cables-and-fuses system group
• Original thread, length, strength class and head geometry for the assigned mounting point

• Do not replace with a visually similar hardware-store screw without verifying every specification

🔌 Function

Secures the specified electrical bracket, cable support, fuse component or adjoining hardware with the designed clamp load.

⚠️ Common Signs of Failure

• Rounded or damaged internal drive
• Stretched, corroded or galled threads
• Incorrect length or strength grade installed
• Loose electrical bracket or cable support
• Fretting around the mounting point
• Fastener damaged during removal from a torque-controlled joint

🛠️ Service Notes

• Use a socket or key that engages the head fully and squarely; a worn or part-inserted tool rounds the flats and turns a simple job into a drilling job
• Clean the threads and the seating face, and check the screw for stretched or corroded threads and a damaged head — renew rather than reuse anything doubtful
• Where the original was fitted with a thread-locking or sealing compound, or with a washer or seal, fit the same again; many of these screws seal a fuel or oil passage as well as clamping it
• Tighten to the figure and sequence given in the workshop manual for your engine, working evenly across a multi-screw joint rather than pulling one screw fully down at a time
• A smear of a suitable marine anti-seize on exposed threads makes the next removal far easier, but keep it off threads meant to be locked or sealed
