Simpson Hans Helmet Quick Release Anchor

M6 quick release helmet anchor.
For use with M61 Dual end tether (HYM61.DE).
SFI 38.1 and FIA approved. FIA standard 8858-2010 only approves helmets with the nut washer built in the helmet. If you purchase post anchors with nut washers from Simpson, you accept that these anchors do not comply with the FIA regulation. If you purchase anchors without nut washers for use with helmets having a built in M6 terminal, these are fully FIA approved. Both types of anchors (with or without nut washers) are fully SFI approved.
