This product I purchased in the Collated Fasteners category is a game changer for my industrial and scientific needs .I have used a variety of collated fasteners from different brands previously but none of them have been as efficient and reliable as these. Through trial and error, I found that these fasteners hold up much better under pressure and have a better grip on materials. The only con to this product is the price, as it is slightly more expensive than some of its competitors. However, the quality and efficiency make it well worth the investment..
