Shipment was fairly prompt
Shipment was fairly prompt. Unfortunately I could not use the fasteners I ordered because I ordered the wrong size.

Great quality and selection
I continue to be impressed with Monster Bolts selection and quality. All fasteners are packaged in plastic bags for each unique fastener. After several instances of purchasing different sizes and types of fasteners they have demonstrated a clear focus on customer needs that includes an effective website purchasing process. Shipping times are fast and the days experienced in shipping from Florida to the opposite of the country are reasonable. Great supplier!

I needed 1 specialty screw
I needed 1 specialty screw.
Monster Bolts had it but I had to purchase a package of 50, when I received the package it was 5 bags of 10.
I find it frustrating but I got what I needed.

Sorry to hear about the frustration. We try and combine when we notice it, but looks like this one slipped by Brandon. Again, sorry this wasn't up to our normal standards for you.
