Blind threaded Avdel Hexsert outputs high levels of joint clamp force comparable to weld and clinch nuts in high-torque applications involving tubular steel, hydroformed parts, and magnesium castings. Band annealing process softens wall of insert to provide sufficient ductility for installation, while retaining properties of hardened thread region. If excessive torque is applied, screw shank fails, not insert, to avoid stripping. Sizes come in M6, M8, and M10.
