These versatile fasteners feature a hexagaonal head allowing for tightening with a wrench. Only a portion of the length is threaded, the remainder is referred to as the shank. The unthreaded section contributes to structural integrity, enhancing strength.
Stainless Steel fasteners are highly resistent to corrosion, and temperature extremes. Used in industries operating in challenging environments, such as outdoor and marine, automotive, food processing and renewable energy.
