S/S 12pt. Nut - 1/4-20 (1)

The S/S 12pt. Nut - 1/4-20 from ARP is a precision stainless steel fastener engineered for critical mechanical assemblies where corrosion resistance and reliable torque retention are non-negotiable. Designed for use in high-performance engine builds, marine applications, and demanding industrial environments, this 12-point nut offers superior engagement compared to traditional 6-point designs. Whether you're assembling a racing engine, restoring a classic vehicle, or securing components in a salt-water or chemically harsh setting, this fastener delivers the durability and dependability that professionals demand.

Manufactured from polished stainless steel, the S/S 12pt. Nut - 1/4-20 features a 5/16-inch 12-point head geometry that provides multiple contact points for socket engagement, reducing the risk of rounding and slippage under high torque loads. The 1/4-20 thread specification—1/4-inch diameter with 20 threads per inch—ensures compatibility with standard 1/4-inch bolts and studs across automotive, industrial, and fastening applications. The polished finish not only enhances corrosion resistance by removing surface impurities but also allows for easy visual inspection of thread condition and wear. Stainless steel construction provides superior resistance to rust, oxidation, and chemical attack compared to zinc-plated or plain steel alternatives, making it ideal for long-term, maintenance-free service.

Engine builders and motorsports professionals rely on ARP fasteners for critical applications where failure is not an option. The 12-point design proves especially valuable when working in tight engine compartments or frame areas where accessibility limits socket orientation flexibility—the additional contact points allow technicians to apply consistent torque from multiple angles. This nut is sold individually (one per order), making it suitable for specific repair applications, complete engine rebuilds, or incremental assembly projects. Always verify thread compatibility with your specific bolt or stud before installation, and use a calibrated torque wrench to achieve proper clamping force according to your application's engineering specifications.
