Honda Flange Bolt 14×77 Premium Alloy Steel

Description

Product Overview

The Honda 90181‑S7A‑000 flange bolt is a premium replacement fastener engineered for the 2009 Civic 4D and CR‑V Element models. Constructed from high‑strength alloy steel, this bolt meets Honda’s manufacturer grade “premium” specifications and carries a hardness rating of Grade 10.9, ensuring it can withstand the high‑torque demands of engine mounting. With a 14 mm (0.55 in) diameter, right‑hand thread, and a flange head style, the bolt provides a large bearing surface that distributes load evenly, reducing the risk of deformation or loosening over time. The smooth exterior finish aids in corrosion resistance, while the unf (Unified National Fine) thread type guarantees a secure, vibration‑resistant connection.

Usage

Designed for direct fit applications, this bolt replaces the original OEM part without the need for modifications. It is ideal for engine main bolt replacement, suspension component mounting, and any situation where a robust, high‑precision fastener is required. Automotive technicians and DIY enthusiasts alike will appreciate the bolt’s compatibility with standard torque specifications for Honda engines, making it suitable for routine maintenance, performance upgrades, or repair of worn‑out fasteners.

FAQ

Is this bolt a direct replacement for my 2009 Civic?

Yes, the 90181‑S7A‑000 flange bolt is a genuine OEM part that fits the 2009 Civic 4‑door model without any modifications.

What torque specification should I use when installing this bolt?

Honda recommends a torque of 85 Nm (63 lb‑ft) for the engine main bolt. Always refer to your vehicle’s service manual for the exact specification.

Can I use this bolt for other Honda models?

The bolt is specifically sized for the Civic and CR‑V Element. While it may physically fit other models with the same thread size, we advise confirming compatibility before installation.

How does the flange head improve performance?

The flange head provides a larger bearing surface, which spreads the clamping force more evenly across the mating surface. This reduces the likelihood of the bolt pulling through the material and helps maintain a secure connection under engine vibration.

Is the bolt coated for corrosion resistance?

The bolt features a smooth exterior finish that offers basic corrosion protection. For environments with extreme exposure to moisture or road salt, applying a compatible anti‑corrosion coating after installation is recommended.
