Head Bolt Set for Nissan QR25DE with Internal Hex

Cylinder head bolt set for the Nissan engine. Designed to OEM specifications to ensure correct clamping force and a reliable head gasket seal.

Head bolts are a critical fastener — correct torque and stretch values are essential for preventing head gasket failure. Always replace head bolts when performing a cylinder head rebuild, as used bolts may have stretched beyond their serviceable limit.
