Important: We recommend the use of Blue Loctite on the hex screw threads. This will provide a firm hold and still allow easy removal when necessary.

ISMI premium springs are manufactured exclusively with certified aerospace specification alloys; stainless or chrome silicon. Then the springs are heat treated, shot peened and stress relieved after winding to enhance performance and durability.
