Magnetic suction wrench catheter locking wrench kit three-in-one set, H251 model, includes three wrenches in orange, grey and black with crescent, magnetic and locking designs for versatile workshop, plumbing, and DIY tool applications
H251 Magnetic Crescent Catheter Locking Wrench Set: Three Specialised Tools in One Kit

This three-piece wrench set combines distinct functional designs for various mechanical, plumbing, and DIY applications. The H251 model includes a crescent wrench for adjustable bolt sizing, a magnetic suction wrench for securing small metal components, and a catheter locking wrench designed for tubing and fitting work. With three different wrench types in one package, users have access to specialised tools for different tasks without needing separate purchases. The set's compact dimensions and lightweight construction make it suitable for workshop use, toolboxes, or on-site repairs where multiple wrench functions might be required. Each wrench has specific measurements and weights, providing distinct handling characteristics suited to their particular functions.
Features and Construction

The three wrenches in this set each serve different purposes while forming a cohesive toolkit. Their metal construction provides the necessary strength for light-to-medium duty applications, with each design optimised for specific mechanical tasks. The magnetic suction wrench incorporates magnetic components to hold small parts, while the catheter locking wrench features a design suited to gripping tubing and fittings securely.
Material and Build
The wrenches feature metal construction suitable for their intended mechanical functions. The magnetic suction wrench includes magnetic components that enable it to secure small metal parts during work, reducing the risk of dropping components. This material choice provides the necessary structural integrity for typical wrench applications while keeping the overall set weight manageable at approximately 94.3 grams total. Each wrench's build corresponds to its specific function, with the crescent design allowing adjustable sizing, the magnetic version offering part retention, and the locking design providing secure grip on tubing.
Size and Practical Fit
The three wrenches have distinct dimensions that influence their handling and storage. The orange wrench measures 15cm in length, 3.2cm in width, and 4.5cm in height, making it the most compact option. The grey wrench is slightly longer at 16.5cm while maintaining the same 3.2cm width and 4.5cm height. The black wrench shares the 16.5cm length but has increased width at 4.2cm and height at 5cm. These dimensional differences correspond to each wrench's specific function, with the larger black wrench likely providing more leverage or accommodating different components. The varied sizes allow users to select the appropriate tool based on both the task and working space constraints.
Uses and Placement

This wrench set supports multiple application scenarios through its combination of specialised designs. The crescent wrench handles adjustable bolt and nut sizing, the magnetic suction wrench works with small metal components, and the catheter locking wrench addresses tubing and fitting requirements. This versatility makes the set applicable across different environments and task types.
Event or Professional Use
In workshop or professional settings, this three-wrench combination provides quick access to different tool functions without requiring multiple separate purchases. The magnetic suction wrench can secure small screws, bolts, or other metal components during assembly or disassembly work. The catheter locking wrench offers specific utility for plumbing or fluid system applications where tubing needs secure gripping. The crescent wrench provides adjustable sizing for various bolt dimensions that might be encountered in repair or maintenance tasks. Having all three designs available supports efficiency in environments where different wrench types might be needed throughout a workday.
Everyday Home Use
For household DIY and maintenance, this set covers multiple common wrench requirements in a compact package. Home repairs often involve different fastener types, small component handling, and occasional plumbing work, making the three distinct wrench designs particularly useful. The lightweight construction at approximately 94.3 grams total makes the set easy to store in home toolboxes or carry to different repair locations. The magnetic function helps prevent loss of small metal parts during furniture assembly, bicycle repairs, or appliance maintenance. The compact dimensions allow for storage in limited space while still providing three functional tools.
Benefits and Buying Value

The combination of three specialised wrench designs in one set offers practical advantages for users with varied mechanical needs. Rather than purchasing separate tools for different functions, this kit provides multiple solutions in a single package. The distinct designs address different task requirements while maintaining a cohesive toolset approach.
Reuse and Low Maintenance
These metal wrenches are designed for repeated use across various applications. Their construction supports durability for typical wrench functions without requiring specialised maintenance. Keeping the tools in a dry storage location helps prevent corrosion and maintains their functional condition over time. The magnetic components in the suction wrench provide ongoing part-securing capability without needing replacement or adjustment. The set's design allows users to apply the appropriate wrench type to different tasks as needed, extending the toolkit's usefulness across multiple projects and repair scenarios.
Why Choose This Product
This wrench set provides three distinct functional designs in one compact package, offering versatility for users with varied mechanical needs. The combination of adjustable crescent, magnetic suction, and catheter locking functions addresses different task requirements without requiring separate tool purchases. The specific measurements of each wrench – 15cm x 3.2cm x 4.5cm for orange, 16.5cm x 3.2cm x 4.5cm for grey, and 16.5cm x 4.2cm x 5cm for black – correspond to their intended applications and handling characteristics. At approximately 94.3 grams total weight, the set remains portable while providing three functional tools. This approach makes practical sense for users who need multiple wrench types but prefer consolidated tool storage and purchase.
