Category: Flange Bolt
Product description
- Drive & Head Profile: Features an external 12-point star / Torx flange head designed to optimize tool engagement, prevent camouflage slippage, and allow superior torque transmission during automated or manual tightening.
- Design & Aesthetics: Clean, minimalist product presentation with strictly no manufacturer logos or head markings, ideal for premium replacement kits, high-end automotive builds, and professional display.
- Integrated Flange Base: The wide integral flange face evenly distributes high clamping forces over a larger surface area, eliminating the need for separate washers and safeguarding joint integrity.
- Versatile Finishes & Lengths: Offered in both long-shank cylinder head bolt configurations and shorter mounting styles. Available in silver corrosion-resistant coatings (such as Dacromet/Geomet) and black oxide/phosphate surface treatments.
- Material & Grade: Forged from high-grade alloy steel (Grade 10.9 / 12.9 equivalents) to withstand extreme thermal expansion, mechanical strain, and high fatigue conditions.
- Applications: Specially designed for automotive cylinder head fastening, engine blocks, flywheel assemblies, driveshafts, suspension systems, and heavy-duty industrial machinery requiring high-torque precision.
