Description
The Large Cross Recessed Flat Head Screw is a high-performance threaded fastener engineered for exceptional reliability and enhanced corrosion resistance. This specific screw adheres to the Japanese Industrial Standard (JIS B 1111T) and is characterized by its large, slightly domed, flat head which provides a greater bearing surface than standard screws. The cross recessed drive allows easy installation with standard tools while preventing slippage during tightening. The cross recessed flat head screw is constructed from premium 316 Stainless Steel, offering superior anti-corrosion properties and making it the preferred choice for demanding environments. Engineered for strength and reliability, this machine screw is widely used in demanding applications across industrial, commercial, and marine sectors.
Features & Benefits
- Premium 316 Stainless Steel: Exceptional resistance to rust, oxidation, and corrosion, ideal for marine and high-humidity environments.
- Large Flat Head Design: Offers a larger bearing surface area, which improves clamping force and reduces the risk of pull-through, ideal for securing thin materials.
- Standard Cross Recessed Drive: Features a standard cross groove, making it a standard part that is easy to lock and is less prone to slipping during installation.
- Deep & Uniform Thread: The precision-cut thread is deep, ensuring uniform force distribution for a secure and reliable mechanical connection.
