31PCS Magnetic Nut Driver Set, Impact Drill Driver Bit in Cr-V, SAE & Metric Power Nut Drivers with Quick-Release Extensions & 1/4" Hex Shank

A very solid/strong set of drivers. The whole set is quality, from the case to hold them to the actual drivers. When I first got them, I was surprised at the heavy weight (1.207Kg including case), but that in itself is a sign of quality. Unlike some sets where you get the heads that then fix on to a shaft, these drivers all have their own shaft built in, but there are three different length extension rods with locking ends that you can use to extend the shaft length. In fact, I found that the extension rods can also be used for holding hexagonal screwdriver heads, which also lock in place. Unlike a socket set this set is designed to fit into a drill bit rather than a socket wrench. The 31 pieces are all labelled with their size and have either a blue or red ring on them identifying metric mm or imperial inches sizing. The range of sizes is good ranging from 5/32” to 9/16” imperial and 4mm to 14mm metric. The depth of each socket is good, but varies with size. The overall quality is very good and although I am not familiar with the make KRETLAW they appear to be as good as the best.

This is a well laid out and compactly presented set of nut drivers. Split into two colour coded halves for imperial and metric, plus the inlusion of extension pieces to give up to a 20cm reach for hard to reach nutsThese all come well organised in a high quality rigid zipped pouch. The zipper is not branded but appears to function well

Used the 14mm bit on my impact driver and it worked ok, the bolt wasn't rusted or stuck solid. This seems to be a good set, haven't heard of this make before but looks to be sturdy enough, we come across so many small awkward nuts and bolts when working on the cars and this set looks to be very handy, whished we'd had this the other day as the tiny bits would have been very helpful, excluding the extensions the length of the bits are 65mm and the magnetic power is quite strong. The case is strong, a thick canvas and webbing, the zip runs round 3 sides so this case opens out flat and also has a strong hanging loop attached.

KRETLAW 31PCS Magnetic Nut Driver Set arrived well-packed. The set is strong and made from good-quality materials. It also comes with a pouch to keep everything organized and safe. Each driver bit is labelled with its size, making it easy to pick the one you need. Good value for money.

The magnetic tips are strong enough to securely hold fasteners, even when working in tricky positions or upside down. The magnets do not degrade over time or get clogged with metal shavings, which is a common issue with some lower-quality sets.The nut drivers fit snugly onto bolts and nuts, which reduces the risk of stripping or slipping. I particularly appreciated the accuracy of the sizing, especially in the smaller metric sizes.The set is designed for use with impact drivers, and it performs exceptionally well under the high torque that these tools generate. Even under heavy use, there was no chipping, cracking, or significant wear. The 1/4" hex shank allows for quick bit changes.

The set also includes 3 impact socket adapters (1/4'', 3/8'', and 1/2''), a 60mm magnetic bit holder, and 3 quick-release extensions (60mm, 100mm, and 150mm).The quality is outstanding, with attention to detail that shows in the powerful magnets embedded in each driver, ensuring a secure grip on nuts and bolts. The universal 1/4" hex shank works perfectly with my drill and wrench, making it incredibly convenient for various jobs.The set is stored in a compact, convenient case, keeping everything neatly organised and ready for use. For the price, this kit offers excellent value for money, and I'm really happy with the purchase.

I needed these for years. Helped me out all my projects together with ease! Everyone needs a set of they do lots of DIY projects. Sturdy nylons case keeps everything organize and accounted for.

Hier ist alles dabei, was das Bastlerherz freut, tolle Verarbeitung.Alles ist in einer Tasche gut gesichert an seinem Platz.Besonders gefallen mir die Bitverlängerungen und die

I’ve been acquiring various tools so that I have them available both at home and at my new shop space away from my house. I got these to close a gap and coincidentally needed these almost immediately to use on some fasteners where neither a wrench nor a standard nut driver were suitable to get the nuts started on the screws. The ad states that they can be used in impact drivers, but I’d try to avoid that, especially for tightening. The only thing odd about this set is that it has a few imperial and maybe metric sizes that, to my knowledge, have no use; for example 7/32, 9/32, and 11/32. Eliminating these might bring the cost down slightly.

Das Set ist prima. Es kommt in einer handlichen Box, die genauso sauber verarbeitet ist wie die Steckschlüssel selbst. Damit kann man prima Ordnung halten. Die Materialqualität scheint für mich völlig i.O. zu sein und der Preis ist meiner Meinung nach angemessen.

This is a well-made, comprehensive set of nut drivers. The variety of sizes is helpful, the sturdiness of the construction gives confidence about their longevity, the magnetic bases helps a great deal in securing bolts and getting them started, and the carrying case keeps it all together in a handy way. Good product!
