Set specification: 18 pieces, covering 6/7/8/9/10/11/12/13/14/15/16/17/18/19/20/21/22/24mm (full-size coverage of commonly used bolts, eliminating the hassle of missing specifications)
Storage design: roll-up canvas tool bag (unfolded size: 71×39cm, folded size: 40×11×5cm), with independent card slot + orange edging, clear tool placement, and easy to carry without taking up space.
Weight: Total weight 2.3kg (individual weight 0.020–0.304kg, small size is lightweight, large size is sturdy)
II. Core Values: Full-Scenario Adaptability + Storage Revolution
1. Specification coverage "no dead ends"
From 6mm (such as electronic devices, bicycle screws) to 24mm (such as automobile chassis, mechanical bolts), 18 specifications are seamlessly connected to meet:

Vehicle maintenance: engine compartment (8-19mm), tire and wheel hub (17-22mm), chassis suspension (14-24mm);
Home improvement projects: furniture assembly (6-12mm), home appliance maintenance (7-14mm);
Industrial assembly: mechanical equipment (10-24mm), hardware installation (6-20mm).
2. Rolling storage "Instant tidying"
Canvas material: wear-resistant and tear-resistant, durable for outdoor/workshop environments;
Independent card slot: Each wrench is precisely inserted to avoid shaking and collision. When stored, it is "stable at a single insertion" and "easily found at a glance" when needed;
Foldable and portable: With a compact size of 40×11×5cm, it can easily fit into a tool bag or trunk, providing no burden during outdoor work.
III. Design and Material: Durable, Precise, and User-Friendly
1. Wrench craftsmanship
Material: Forged from chrome vanadium steel (Cr-V), with quenching and tempering treatment, it boasts high strength and excellent torsional resistance, making it resistant to deformation even after prolonged use;
Surface treatment: mirror polishing + anti-rust coating, preventing rust and jamming, easy to clean with oil stains;
Opening accuracy: Laser-cut openings ensure tight engagement, eliminating the risk of "slipping and damaging bolts", and are compatible with standard hex nuts.
2. Ergonomic details
Straight shank design: Natural force application angle, solid grip with large-sized wrenches (such as 21/24mm), and flexible operation with small-sized ones (such as 6/7mm);
Length adaptability: Small-sized short handles (e.g., 6mm in length and 104mm in length) are suitable for narrow spaces (such as the interior of a chassis), while large-sized long handles (e.g., 24mm in diameter and 288mm in length) facilitate the application of high torque.
IV. Applicable Scenarios & Comparative Advantages
✅ Compared to single-piece wrenches: The 18-piece set is fully equipped at once, avoiding the embarrassment of "missing specifications at the last minute" and offering better value for money;
✅ Compared to boxed sets: The rolled cloth bag is more portable and allows for 3 times faster storage (just roll it up and go vs. cumbersome unpacking/repacking with boxed sets);
✅ Compared to inferior sets: Cr-V material + precise openings, with 50% improved durability, bid farewell to the frustration of "the teeth slipping after just a few uses".
V. Usage and maintenance tips
Storage guidelines: After use, promptly return items to their designated locations, roll up the cloth bag tightly, and avoid jostling or abrasion of tools inside the bag;
Rust prevention maintenance: Clean and apply light anti-rust oil (such as WD-40) monthly, with extra attention in humid environments;
Safe operation: Choose the right specification before applying force to avoid damaging tools/bolts by using a "small wrench to tighten a large screw".
