Left-hand thread hex bolts, fully threaded, 8.8 are reliable and robust screws used to create strong joints in various construction and machinery applications. They are manufactured in hardened steel with a strength class of 8.8, which indicates high tensile strength and breaking strength. They are used together with a left-hand thread nut or in left-hand threaded holes. Left-hand threads are also known as reverse threads, which means that the bolt is tightened by turning it counter-clockwise onto matching threads.
