Replace a damaged or missing thumb screw spring so your thumb screw bolt will help keep lashing wire coil doors from opening and dropping out your lashing wire. This small spring does real work, keeping the thumb screw in posistion as the coil gets smaller and the wing nut gets loose.
At this price, keep a few spares in the truck and in the parts drawer. Like all lasherparts.com lasher parts, this spring matches the original fit and function.
