a head depth, the bolt head depth being less than the receiver head depth; and

a head bearing surface; and

a bolt shank comprising:

a bolt shank diameter; and

a bolt shank depth;

wherein the head bearing surface rests against the receiver bearing surface;

wherein the bolt head cannot rotate more than 90 degrees;

wherein the nub prevents the bolt from dislodging from the bolt receiver by gravity; and

securing the plastic wheelbarrow tub to a wheelbarrow frame by screwing a nut to the bolt shank.

13 . The method of attaching a plastic wheelbarrow tub to a wheelbarrow frame of claim 12 wherein the nut is a nylon insert lock nut.

14 . The method for attaching a plastic wheelbarrow tub to a wheelbarrow frame of claim 12 wherein the receiver shaft comprises two nubs.

15 . The method for attaching a plastic wheelbarrow tub to a wheelbarrow frame of claim 12 wherein the receiver shaft comprises three nubs.

16 . The method for attaching a plastic wheelbarrow tub to a wheelbarrow frame of claim 12 wherein the nub is formed as part of the wheelbarrow tub.

17 . The method for attaching a plastic wheelbarrow tub to a wheelbarrow frame of claim 12 wherein the nub is located distal to the receiver bearing surface.

18 . The method for attaching a plastic wheelbarrow tub to a wheelbarrow frame of claim 12 wherein the nub is located adjacent to the receiver bearing surface.

a head depth, the bolt head depth being less than the receiver head depth; and

a head bearing surface wherein when the bolt head bearing surface is in contact with the bolt receiver head bearing surface the bolt head cannot rotate; and

a bolt shank comprising:

a bolt shank diameter; and a bolt shank depth; and

a nut configured to screw onto the bolt shank.

21 . A system for attaching a plastic wheelbarrow tub to a wheelbarrow frame comprising:

a wheelbarrow tub comprising a bolt receiver bore having a bolt receiver wall defining a bolt receiver bore diameter;

a wheelbarrow frame;

a bolt comprising a bolt shank; and

a nut configured to screw onto the bolt shank;

wherein the bolt receiver bore comprises a nub that extends from the bolt receiver wall into the bolt receiver bore to provide resistance to the bolt shank sliding therein.
