Seachoice 59994 Stainless Steel Toggle Bolts – 1/4-20

Parts Desk Insights
Best suited for boaters mounting accessories, panels, or hardware to hollow bulkheads or deck surfaces where there is no access to the back side of the material — a common situation when adding electronics, grab handles, or accessories to an existing interior. Toggle bolts are the correct solution when you can’t use a through-bolt with a backing plate. The 1/4-20 size is the right choice for most light-to-medium duty mounting applications; confirm the bolt length needed by adding the wall thickness plus the thickness of the item being mounted to the minimum 1/2" requirement. For heavier loads or structural mounting, a through-bolt with a backing plate is always the stronger option.
