Flomore U-Bolts Editorial Review
The M6x20x45mm Square U Bolt made from 304 stainless steel has garnered a positive response from customers who appreciate its strength and durability. Many users noted that the metal's hardness exceeded their expectations for 304 stainless steel, with one reviewer specifically highlighting its toughness during cutting, which burned up a saber saw blade but not a Sawzall blade. The ability to cleanly trim the threads with ease was also praised, making installation smoother. Customers expressed satisfaction with the u bolts’ performance in various applications, from securing privacy fences to supporting roof racks on long trips. The included hardware—four nuts, two washers, and a plate—adds value, although one user pointed out that this detail could be better communicated in the product description, preventing unnecessary additional purchases. However, there were some mixed reviews regarding the Consistency of sizing, with at least one customer encountering a wrongly sized u bolt that led to complications during installation, advocating for more meticulous quality control. Despite this hiccup, the overall Consensus is that these u bolts deliver excellent quality and functionality. **
