15-piece dual-purpose wrench set: covers all specifications from 8mm to 24mm, forged from chromium-vanadium steel + lifetime warranty, sandblasted chrome for rust prevention and durability. Double-ended design with opening and socket, arc-shaped locking mechanism for stability, strong socket torque, longer and thicker handle for ease of use, easy to store in a bag for quick return to use, suitable for auto repair, home improvement, DIY and all-around applications.

It is truly a "all-purpose tool": one end has an arc-shaped opening that precisely fits the arc of the bolt, securely clamping and not prone to slipping, and it can easily fit into narrow corners; the other end is a high-gear sleeve that bites more tightly, ensuring no slippage during high-torque operations, and the twisting efficiency is directly doubled.Are you still frantically searching through a tool box for the missing wrenches? Are you collapsing from the lack of tools to loosen the bolts? The Nan Yu 15-piece dual-purpose wrench set not only neatly stores the "convenience + durability + efficiency" features in the tool cabinet - with one wrench having both an opening and a socket design, covering specifications from 8mm to 24mm - but also provides all the tools for auto repair, home improvement, and equipment maintenance in one set!
「Dual-ended Design」: One function for two tools, saving space and time
It is truly a "all-purpose tool": One end is an arc-shaped opening that fits the arc of the bolt, locking securely and not slipping easily, and can be easily inserted into narrow corners; the other end is a high-gear socket that bites more tightly, allowing for greater torque operations without slipping, and doubling the twisting efficiency.
No longer need to switch between opening wrenches and socket wrenches - loosen with the quick lock of the opening, tighten with the precise force of the socket, a single process flows smoothly, saving half the operation time. Whether it's removing car tires or installing furniture screws, you can "do it all in one go".
「Hardcore Chromium-Vanadium Steel Material」: Ultimate durability
If ordinary wrenches start to peel and deform after two uses? This set of wrenches is made of chromium-vanadium steel forging, with a matte chrome finish on the surface: It has full anti-rust capabilities, and after getting stained with oil, water, or dirt, it shines after a wipe; its hardness can withstand violent tests - for large torque operations, it doesn't bend or chip, and the official warranty is lifetime, allowing for decades of use with just one purchase, making it a "family heirloom" in the tool world.
「15-piece Full Specifications」: From 8mm to 24mm, covering 99% of daily scenarios
You can find it for any bolt size you can think of: 8/9/10mm for household small screws, 12/14/17mm for common car specifications, 21/22/24mm for large equipment bolts - even the easily overlooked 13mm double specification is provided for you. No need to improvise with tools anymore.
The included blue storage bag is an "obsessive's dream": Each wrench has its own dedicated slot, and after use, it is simply plugged in and returned to its place, hanging on the wall without taking up space. The next time you use it, you can glance and find the corresponding size at a glance, eliminating the need to "fish for needles in a haystack".
「Thickened and Extended Handle」: More than just a little bit of effort saved
No longer use the "hand-tightening until sore" small wrenches! This set of wrenches features an extended and thickened handle, fully leveraging the lever principle: for the same bolt, others need to exert all their strength, but you can easily handle it with just a gentle pull; the streamlined arc shape of the handle also fits the palm, reducing hand fatigue during long operations, and your working efficiency will soar!
Whether you are an auto mechanic, a construction worker, or a DIY enthusiast who loves tinkering at home, this Nan Yu dual-purpose wrench set is a "no-brainer" tool necessity - 15 pieces of full specifications + dual-ended dual use + lifetime warranty, one set solves all tightening problems, eliminating "tool anxiety" from your life!
