Bolts M7x40 are fastening elements made of metal, featuring a 7-millimeter diameter and a 40-millimeter length. They are typically used in mechanical and industrial applications where a strong connection is required. This specific bolt size is less common than standard sizes such as M6 or M8 and may be specially employed in specific devices or machines. The threading offers firm grip, while rust-resistant properties ensure durability and reliability. Bolts M7x40 can be used in conjunction with nuts or screwed directly into matching threaded material.
