Bolts arrived well packaged in a bubble package. Bolts were in a heavy sealed bag inside the mailer. All bolts were well form, marked for grade 8. Price was excellent for the quality. Delivery was quick and no trip to the store...saves time and gas money. I recommend buying in bulk from this supplier.

No sense using Grade 8 bolts without the proper nuts. Nylon inserts keep severe vibration from loosening

hex head bolts were great quality but what I am very pleased with is the fact that the bolts were in a sealed plastic bag INSIDE a good quality cardboard box ( in other words the bolts were not loose and banging around inside the shipping box )

I purchased these bolts for restoration project on a Jeep CJ5 I've been having trouble finding the certain size of bolt and the grade that I needed at my local hardware stores normally I wouldn't purchase items like this online because I like to see the quality myself but I am very pleased with the product I purchased here the items were a perfect fit or clean they came sealed in an individual bag and also in a sturdy little box with a label that clearly says the size thread count and grade so as a satisfied customer I will be shopping with this distributor again and I would suggest their products

Size: 3/8 USS Flat Washer (50pcs)Verified Purchase
If you’re not using grade 8 washers in those applications of high vibrational stress, you get a suboptimal solution where the washer fails and the grade 8 bolt loosens enough you’ll find the lowest grade metal wears excessively. Use as part of a grade 8 solid fastener solution- indeed “hard to find” but essential nonetheless.
