Nothing is more annoying that having to use the handle every time you want to release your bottle jack. Whether it be on your shop press, or a jack you carry for off-road use. Thes e thumb screws make it much easier to release the jack pressure. Something like doing 20-30 back to back dimple dies on your press, these knobs will pay for themselves in no time!The part was designed around the Harbor Freight 20 ton bottle jack, which has one of the smaller diameter pins for this size jack. If you have a larger release pin that is no problem, simply drill it out. We personally use a jack from amazon that had a larger pin and that is what we did. Double check your pin diameter but should work with any pin from 8.8 to 13mm Show more
