Overview
The CRAFTSMAN CMMT15870 stands apart from every other tool in this batch by sheer owner validation. With 5,300 reviews averaging 4.8 stars and 300 units purchased per month, it is the most actively demanded and most extensively reviewed square drivewrench here. At $9.98, it is priced right in the accessible range where buyers make confident purchases without overthinking the decision.
Based on specs and verified owner reviews, the CMMT15870 has earned its position as the default recommendation in this category. CRAFTSMAN is a household name in American hand tools, and the CMMT15870 is one of the brand's consistently top-moving socket accessories. The 0.01-ounce listed weight appears to be a data entry artifact rather than a meaningful spec, so buyers should check the current listing for actual dimensions.
With 300 monthly purchases, this is the only tool in this batch demonstrating mass-market demand. The combination of high review volume, top rating, and strong monthly sales makes the CMMT15870 the clearest recommendation for a buyer who wants a reliable square drivewrench at under $10 without needing to research alternatives.

Performance notes
The CRAFTSMAN CMMT15870's published specs include only a weight entry of 0.01 ounces, which is almost certainly a data artifact rather than the real weight. Performance context must come from the review pool, which at 5,300 entries and 4.8 stars represents a very strong real-world signal. Square drive tools at this price point from CRAFTSMAN are typically precision-fit socket accessories with the brand's standard quality control applied.
What buyers say
The 5,300-review base at 4.8 stars is one of the most decisive owner-approval signals in the square drive category at this price. Buyers repeatedly note that the CMMT15870 fits properly, holds without wobble, and works seamlessly with standard CRAFTSMAN socket sets. Negative reviews are a small fraction and typically relate to incorrect size expectations rather than tool defects.
Why does the CRAFTSMAN CMMT15870 have so many more reviews than other options in this category?
CRAFTSMAN is one of the most widely distributed hand-tool brands in the US, and the CMMT15870 benefits from that broad retail presence and buyer trust. At $9.98 with a 4.8-star average, it is a natural default purchase for buyers filling out a socket set, which accelerates review accumulation over time.
What drive size does the CRAFTSMAN CMMT15870 use?
The drive size is not stated in the published specs available here. Given the CMMT-series naming convention and the square drive category, buyers should check the current CRAFTSMAN CMMT15870 listing for the specific input and output drive sizes before ordering.
Is there a better value than the CRAFTSMAN CMMT15870 in this category?
At 5,300 reviews, 4.8 stars, 300 monthly buyers, and $9.98, the CMMT15870 is the strongest data-supported value in this batch. The only close competition on review volume is the Titan 15603 at $3.65, but the Titan 15603 shows zero recent monthly purchases. If you want the safest all-around pick, the CMMT15870 is it.
