1. Overview of basic parameters
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. Speci”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 “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 embarrassme”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 fru”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”.
