At $5.39, this is the 3\/4\" bolt that keeps the wheels attached to a tank that weighs significantly more than the 8-gallon units. A 20-gallon portable is heavy enough that losing wheel mobility is a real problem -- dragging it across a shop floor without wheels is not practical, and using an incorrect substitute bolt that shears under load is worse.\u003c\/p\u003e\n\n\u003cp\u003eThe step up from 1\/2\" to 3\/4\" between the AB12 and AB34 is not arbitrary. The 20-gallon portable tank carries substantially more weight, and the axle hardware is sized accordingly. Using the wrong bolt -- even one that fits the hole -- puts the wrong load on undersized hardware. Get the correct OEM part.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cast Air part:\u003c\/strong\u003e Exact fit for 20-gallon portable compressor tank wheel axles -- correct diameter, thread, length, and head specification\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrect 3\/4\" diameter:\u003c\/strong\u003e Sized for the heavier load a 20-gallon portable puts on the axle hardware; larger than the 1\/2\" AB12 used on 8-gallon portables\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect replacement:\u003c\/strong\u003e Installs as the factory original -- no modification, no thread chasing, no adaptation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRight grade for the application:\u003c\/strong\u003e OEM parts are specified for the load they carry; hardware store substitutes are not\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinnesota-made quality:\u003c\/strong\u003e Cast Air manufactures in Minnesota with consistent specifications across their tank and compressor line\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhich Bolt Does Your Tank Take?\u003c\/h2\u003e\n\u003cp\u003eCast Air portable tanks use two different axle bolt sizes.
