FAQS on 5 16 18 hex bolt
Q: What are the specifications of a 5/16-18 hex bolt?
A: A 5/16-18 hex bolt has a diameter of 5/16 inches and 18 threads per inch. It is commonly used in general-purpose fastening applications. The hex head design allows for easy tightening with a wrench.
Q: How does an M14x1.5 hex bolt differ from an M14 hex bolt?
A: The M14x1.5 hex bolt has a metric thread pitch of 1.5 mm, while a standard M14 hex bolt typically has a coarser pitch (e.g., 2 mm). Both share a 14 mm diameter but differ in thread density. Always verify thread pitch for compatibility.
Q: What applications suit an M14 hex bolt?
A: M14 hex bolts are ideal for heavy-duty machinery, automotive components, and structural projects. Their larger diameter provides high tensile strength. Ensure proper torque specifications for secure fastening.
Q: Can an M13 hex bolt replace an M14 hex bolt?
A: No, M13 and M14 hex bolts have different diameters (13 mm vs. 14 mm). Using the wrong size may compromise structural integrity. Always match bolt specifications to the application requirements.
Q: How do I identify the size of a hex bolt?
A: Measure the shank diameter (e.g., 5/16" or 14 mm) and thread pitch (threads per inch or mm pitch). Labels like "M14x1.5" indicate metric sizing. Check markings on the bolt head for grade or material details.
