Aeroflow Performance oil pan bolt kits are engineered to hold and secure your oil pan and gasket in place without the worry of loosening. The bolts are manufactured from aircraft-quality 8740 high-tensile-strength chromoly steel and cold-forged to ensure molecular integrity within the stud. All bolts feature a small 12-point head and hardened parallel washers for an even load distribution and accurate torque readings. These design elements translate to a more precise seal, reduced gasket stress, and fewer re-torques over time.

• Reusability: The bolt construction supports repeated use, helping extend gasket life and reduce maintenance downtime.
• Precise torque and load distribution: Hardened parallel washers and 12-point heads provide even clamping and accurate torque readings in tight engine bays.
• Corrosion-resistant finish: Black finish adds a durable, aftermarket-grade appearance while protecting against moisture and heat cycling.
• Material strength: Aircraft-quality 8740 chromoly steel delivers high tensile strength for demanding engine environments.

Ideal for oil pan installation or replacement on Small Block Chevy builds, this kit ensures a secure, long-lasting seal with components sized to match common SBC oil pan and gasket configurations. Whether you're rebuilding, upgrading, or performing routine maintenance, these bolts offer reliability, repeatable performance, and professional-grade construction.
