FAQS on hex bolt 5 8

Q: What is the difference between a 5/8" hex bolt and an M14x1.5 hex bolt?

A: A 5/8" hex bolt uses imperial measurements (≈15.875mm diameter), while an M14x1.5 hex bolt follows metric standards (14mm diameter with a 1.5mm thread pitch). They are not directly interchangeable due to differing thread specifications.

Q: Can an M14 hex bolt replace an M13 hex bolt in industrial applications?

A: No, M14 and M13 hex bolts have different diameters (14mm vs. 13mm). Using the wrong size may compromise structural integrity or cause thread damage in pre-tapped holes.

Q: What material grades are available for M14x1.5 hex bolts?

A: Common grades include Class 8.8 (medium strength carbon steel), Class 10.9 (high-strength alloy steel), and A2/A4 stainless steel for corrosion resistance. Selection depends on load requirements and environmental conditions.

Q: Is a 5/8" hex bolt suitable for automotive suspension systems?

A: Yes, Grade 5 or Grade 8 5/8" hex bolts are often used in suspension components, provided they meet OEM torque specifications and SAE/JIS standards for vehicular applications.

Q: How do I determine thread compatibility between M14 and 5/8" hex bolts?

A: Use a thread gauge: M14 bolts have metric threads (e.g., 1.5mm pitch), while 5/8" bolts use imperial threads (11.5 TPI UNF or 18 TPI UNC). Mixing systems may cause cross-threading or loosening under vibration.
