Reasonable prices for 316 stainless!
Got some metric bolts and washers in 316 stainless for far less than most suppliers. Each size came in clearly marked ziploc bags. A pleasant experience!

Best prices for high quality R/C hardware, shipped fast!!!
I build R/C cars. I race them too. Its important to have access to high quality, high strength hardware in these buggies. They actually take a beating on the track!
I had been trying to find good pricing on small hardware in some quantity for a while. I was finding places that had high prices, low grade hardware, sold 'per item', difficult to navigate sites and even a place that didn't reply at all! My friend and fellow hobbyist suggested MonsterBolts.com after I told him about my troubles.
It took me about 10 mins to open the site, be very impressed and place my first, pretty large order!
It was here in 2 days!!!
I am 100% pleased with my order, the site, the prices, the stock, the shipping ALL perfect. I am a tough customer and I'm VERY HAPPY!
I am already assembling my next order.
