Manufactured from A4 (316) stainless steel, this M4 x 0.7mm hex tap bolt delivers the corrosion resistance needed for marine, chemical, and high-humidity environments where standard stainless grades fall short. The 316 designation indicates added molybdenum content that significantly improves resistance to chlorides, saltwater, and aggressive chemicals. The partial thread shank below the hex head carries shear loads through solid bolt body rather than across the threads, improving fatigue life and joint performance under lateral forces. These tap bolts are widely specified for boat and dock hardware, food and beverage processing equipment, medical devices, and chemical plant assemblies where long-term corrosion-free service is required.
A Hex Bolt is measured as: Diameter - Thread Pitch x Length from Under Head
