Overview
The Blulu 9/16-inch (14mm) Power Nut Driver is sold as a single piece, per the listed piece count of 1, designed as a hollow socket nut runner sized for 9/16-inch or 14mm fasteners. At 13.28 ounces, it has some heft for a single driver bit, consistent with a hex-shank design meant for power tool use rather than hand turning.
It holds a 4.2-star rating from 331 reviews, the lowest rating among the products in this batch, though it still clears ToolHandle's 3.8-star quality floor. The review count is also the smallest sample size in this batch, which should be weighed when comparing it to sets with thousands of reviews.
At $11.99, monthly demand comes in at 300 units, a solid figure that outpaces several other single-price-point drivers in this batch despite the lower rating, suggesting steady interest specifically in this 9/16-inch size.

Performance notes
At 13.28 ounces for a single hex-shank driver, the Blulu unit is built with enough weight to suggest a solid hollow-socket construction for the specified 9/16-inch (14mm) size. Its 4.2-star rating, while the lowest in this batch, is drawn from a smaller 331-review sample, and the 300-unit monthly sell-through shows there is real, ongoing demand for this specific size from buyers running it off a power drill or impact driver.
What buyers say
At 4.2 stars from 331 reviews, buyer sentiment is more mixed than the other products in this batch, though still within ToolHandle's quality floor. The 300-unit monthly demand indicates enough buyers find it does the job for this specific 9/16-inch size, even if satisfaction is less uniformly high than the top-rated sets here.
