Quality bolts Back ordered on original shipment - took a week + to receive if time sensitive

Came with a hex head on one end and threads on the other, it is a fine 1/2 bolt. Flawless same-day shipping by ACS made this bolt better than AN bolts you can buy elsewhere.

Exactly as described. High pressure fuel pump is generally used on injected engines, low pressure pump for carbureted engines.

When I need an aircraft bolt quick and for a good price, Aircraft Spruce is where I get it. I like that they ship it with a fixed shipping cost and not as need to be determined like some others. Ive been unpleasantly surprised by that a few times.
