🔧 Product Description

Genuine hexagon-socket screw manufactured to the Volvo Penta thread, length, shoulder, strength and corrosion-protection specification assigned to part number 21360480.

⚙️ Key Features

• Genuine Volvo Penta socket-head fastener
• Application-specific thread and installed length
• Factory strength and shoulder geometry
• Designed for the assigned engine or drive clamping load
• Torque must be taken from the exact service procedure

🔌 Function

The screw secures the assigned component with the specified clamping force and alignment.

⚠️ Common Signs of Failure

• Screw found backed out or slack at inspection
• Movement, rattle or a leak at the joint the screw clamps
• Hexagon socket rounded out so a key will no longer grip
• Socket packed with paint, salt or debris, hiding the fault until removal is attempted
• Thread galled or corroded so the screw seizes on the way out

🛠️ Service Notes

• Clean the socket out fully and use the correct key size - a partly engaged key is what rounds these screws
