The A2-70 Stainless Steel T-bolt is a corrosion-resistant fastener made from austenitic stainless steel (usually 304 or 304L). Its material grade, denoted by “A2,” ensures acid-proof properties and non-magnetism. With a minimum tensile strength of 700 N/mm² (or 700 MPa), A2-70 bolts strike a balance between strength and corrosion resistance.
