FAQS on 7 hex bolt

Q: What are the specifications of a 7 hex bolt?

A: A 7 hex bolt typically refers to a hexagonal bolt with a 7mm diameter. However, common related sizes include M14x1.5, M14, and M13 hex bolts, which specify metric thread dimensions (e.g., M14 = 14mm diameter). Always confirm thread pitch and length for compatibility.

Q: What distinguishes an M14x1.5 hex bolt from an M14 hex bolt?

A: An M14x1.5 hex bolt has a 14mm diameter and a fine 1.5mm thread pitch, while a standard M14 hex bolt may have a coarser default pitch (e.g., 2mm). The thread pitch affects grip strength and application suitability.

Q: Can an M13 hex bolt replace an M14 hex bolt?

A: No, an M13 hex bolt (13mm diameter) is smaller than an M14 bolt (14mm diameter), leading to mismatched threads and potential instability. Use only size-matched bolts unless specified by the manufacturer.

Q: Where are M14x1.5 hex bolts commonly used?

A: M14x1.5 hex bolts are often used in automotive and machinery applications requiring precise thread engagement, such as engine components or suspension systems. Their fine pitch ensures secure fastening under vibration.

Q: How do I identify the correct hex bolt size (e.g., M14 vs. M13)?

A: Measure the bolt’s diameter (across the threaded shaft) and thread pitch (distance between threads). For example, M14 bolts measure 14mm in diameter, while M13 bolts are 13mm. Use calipers or a thread gauge for accuracy.
