Used these to replace Bolts on an old MTD Lawn Tractor. Much tougher than the original bolts, and the price was honest. Really appreciate honest sellers here to provide a service, not out to gouge you because you are having trouble finding product locally. Great choice and fast responses to inquiries.

The parts were received quickly and were in excellent shape which is what I needed for a new product I am building. Very pleased and will do business with them in the feature.

The bolts and nuts are as I expected, but it is sure hard to find what I am looking for in this category. If I am looking for a specific diameter, thread and length, I get an assortment of options and most of them do not match my search criteria.I like the chart method where you select the head, material they are made of, driver type, thread, length and grade etc. and then only show what I selected. Not other fastener products that do not match what I selected if this method is even an option.

Used these for replacing rivets in a 2000 chevy van door for the power window regulator and power locks with a threading bit. Was short enough I didn't need to cut down the length for the window, power locks required much shorter bolts and just cut the length in half with sawzall and bench vise.
