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!

Top notch quality, materials, and delivery. Just wish I could order custom spec bolts without having to order half a million at once.
