23 Essential Maintenance Tools Every Technician Needs in 2025

Ever tried to fix a loose screw only to discover you’re missing the wrench you need? A simple mishap like this can turn a quick repair into an hours-long ordeal. In manufacturing, not having the right maintenance tools can lead to hours or days of unplanned downtime that cost a business tens of thousands of dollars unnecessarily, showing just how essential proper tool inventory management is.

In this guide, you’ll come to understand the essential tools that every maintenance technician should have in their tool set — from hand tools to electrical and power tools to storage and safety gear. Let’s dive in!

Hand Tools

Hand tools are the foundation of any maintenance toolbox, providing accurate, controlled means for performing minor fixes and major projects successfully. Maintenance techs should always have the following tools handy:

Screwdriver

Both flathead and Phillips screwdrivers tighten and loosen screws of various sizes. It’s required for opening device panels, fixing loose hinges or securing electrical components. Technicians should always have a screwdriver set on hand to assemble (and disassemble) machinery, make bracket adjustments and carry out all kinds of equipment maintenance.

Hammer

A hammer delivers impact for driving and removing nails as well as shaping materials. It’s used for securing fasteners, assembling machinery and misaligned parts and breaking apart stuck components.

Adjustable Wrench

An adjustable wrench supports a variety of nut and bolt sizes, limiting the need to carry multiple wrenches. Maintenance technicians need it to tighten and loosen bolts in equipment, make machine adjustments, assemble or disassemble components and secure pipe fittings or fasteners in tight spaces.

Allen Wrench

An Allen wrench, or hex key, is used to tighten or loosen hexagonal socket screws that are often used in machinery assemblies and for fastening panels. This tool helps to secure parts in tight spaces, making accurate adjustments and assembling or disassembling components that use hex fasteners.

Saw

A high-quality saw can cut through metal, plastic or wood with the proper blade. It’s essential to shape and trim with precision.

Pliers

Pliers let you bend, twist or hold objects firmly. They are particularly useful for gripping small and  slippery parts, cutting wires, removing staples and nails, crimping connectors and shaping metal or other materials.

Socket Set

A socket set secures nut and bolt fitting, mitigating risk of damage and speeding up maintenance processes. It is useful for quick adjustments and equipment assembly, offering efficiency with a variety of nut and bolt sizes.

Electrical Tools 

Electrical tools are needed to diagnose and repair electrical systems, from testing circuits and connections to stripping wires and securing terminals for effective troubleshooting and maintenance of electrical components.

Multimeter

A multimeter measures current, resistance and voltage to identify and troubleshoot electrical issues like faulty wires or testing power supplies.

Wire & Cable Stripper

Wire strippers remove the protective insulation from wires without damaging the conductor and help to prep wires for connections, splicing or terminal attachment. Electricians use them for clean, specific cuts to perform electrical tasks securely and safely. 

Crimper

A crimper attaches connectors to cable to keep connections secure and reliable and to mitigate risk of electrical faults. Maintenance technicians use this tool for equipment wiring and keeping systems from failing.

Power Tools 

Power tools make any maintenance task more efficient, saving time and allowing you to handle tougher materials with less effort.

Power Drill

A power drill is essential for boring holes in wood, metal or masonry and driving screws quickly, making it helpful for assembly, repairs and installing fixtures.

Impact Wrench

An impact wrench provides high torque output with limited strain on the technician. Use it to loosen or tighten stubborn nuts and bolts, especially when working in automotive or heavy machinery settings.

Circular Saw

A circular saw with proper blades can make straight cuts through wood, plastic or metal. Perform fast cuts with precision when using it to fabricate parts, trim materials or modify machine parts.

Orbital Sander

An orbital sander uses abrasive paper to smooth surfaces by rapidly moving it in small orbits. Achieve a polished look on wood, metal or plastic surfaces. Or use it to remove paint.

Storage 

Keep your maintenance tools organized, easy to locate and safe. Extend their lifespans by protecting them from dust, moisture and damage.

Tool Belt

A tool belt ensures that you always have your most important items on hand, saving you time and effort when performing a quick fix. It’s especially useful for tasks that you’re constantly moving or climbing ladders for.

Tool Box

A secure tool bag or box keeps your equipment safe and organized with proper storage. It prevents your tools from rolling around or getting misplaced at a job site, simplifying maintenance processes when you’re on the go.

Shelves

Shelves provide a larger storage space for items like power tools and spare parts. By designating areas for different types of tools and parts, you mitigate the risk of things going missing. This improves parts inventory management, eliminates clutter and saves time for a more efficient work environment.

Safety Gear

Safety gear is a must-have component of any maintenance routine to ensure technician safety and meet industry compliance protocols. This equipment keeps you safe from injuries and prolongs your ability to work comfortably.

Safety Goggles

Safety goggles provide crucial eye protection, keeping your eyes safe from flying debris, dust and sparks. Whether you’re working with corrosive materials or high-speed equipment, you must protect your vision.

Dust Masks

Dust masks filter out fine particles, keeping you from breathing in harmful airborne contaminants like dust and debris when performing tasks like sanding, cutting or working with chemicals. 

Ear Protection Headphones

High-decibel power tools can lead to hearing damage over time. Ear protection headphones reduce noise exposure, letting you focus on the job without risking your hearing.

Gloves

Gloves protect your hands from cuts, scrapes and chemical exposure when handling sharp, hot or dangerous materials. They also give you a firm grip for handling tools, assembling parts and working with slippery or heavy items.

Flashlight

Illuminate dark or cramped spaces to maintain proper vision when working to see what you’re doing and avoid mistakes. Even in bright areas, a focused flashlight beam is a must for effective precision work.

Maintenance Software 

In today’s digital age, computerized maintenance management system (CMMS) software is another critical tool for technicians and facility managers to operate more efficiently and cost-effectively. 

A CMMS software like Coast streamlines work orders, schedules preventive maintenance and inspections, and tracks inventory to limit equipment downtime. As maintenance technicians log every repair and inspection, leaders gain valuable data regarding tool usage and machinery wear and tear, helping with effective budgeting and scheduling. Maintenance software also stores all equipment data in one place, simplifying access to manuals and maintenance histories.
