Victor GS33956 Cylinder Head Bolt Set - 10-Piece M10x1.5 TTY Bolts

The Victor GS33956 Cylinder Head Bolt Set delivers the precise clamping force needed for a reliable, leak-free cylinder head installation. These are torque-to-yield (TTY) head bolts — the connecting elements between the engine block, cylinder head gasket, and cylinder head that seal the combustion chamber as well as oil and coolant passages under extreme temperatures and pressures.

This set includes 10 bolts featuring a Female Star (Torx-style) drive head and a thread specification of M10 x 1.5 x 115mm. Victor Reinz head bolts are manufactured to meet or exceed original equipment specifications, making them a trusted direct replacement for worn or previously used TTY fasteners.

Key Features:

• Thread size: M10 x 1.5 x 115mm
• Drive type: Female Star (internal Torx)
• Torque-to-yield (TTY) design for maximum clamping force
• Meets all OEM manufacturer torque and fitment specifications
• Matched to Victor Reinz head gasket sets for a complete sealing solution

TTY head bolts must not be reused — once stretched during initial installation, they cannot reliably achieve the required clamping load a second time. Always replace with new bolts when performing a cylinder head repair. Cross-reference numbers include: WHT 005 305, WHT 005 305B, T40708-00, 81039300, 81054400.
