Metric Hex Tap Bolts, Stainless Steel A4 (316), M4-0.70 x 45M
Diameter - Thread Pitch: M4-0.7
|
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. 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
