This is a Genuine Nissan Cylinder Head Bolt for the ZD30 engine in a Y61 GU Patrol. These bolts are what clamp your cylinder head down onto the engine block, creating a tight seal for the head gasket. If you're pulling the head off your ZD30, you absolutely must replace these bolts. They are 'torque-to-yield' bolts, meaning they are designed to stretch when you torque them down. Re-using old, stretched bolts is a recipe for disaster, as they won't provide the right clamping force. This can cause your brand new head gasket to fail, leading to overheating and major engine damage.
