Description
Sunex Tools 26-Piece SAE/Metric Long Arm Hex Key Set (98526L) is a professional-grade solution for technicians, mechanics, and assemblers who require a reliable tool for internal hex-drive fasteners. By combining two full sets of measurements into one package, this set eliminates the need for multiple separate kits. The extended long-arm design is the primary functional advantage of this set, providing the necessary reach for recessed bolts and the leverage required to break loose rusted or over-tightened hardware.
Key Features and Benefits:
- Extended Reach Design: The long-arm configuration is engineered to provide access to fasteners located in tight or deep cavities where standard-length keys cannot reach. This added length also serves as a lever, reducing the physical effort required to apply high torque.
- Precision Chamfered Tips: Each key is finished with chamfered edges. This subtle grind on the tips removes sharp burrs, allowing the key to slide into the fastener head effortlessly and minimizing the risk of “rounding out” the bolt.
- High-Strength Material: The use of Chrome Vanadium (CR-V) steel ensures the tools maintain their shape and edge even after repeated use on high-torque applications.
- Dual-Standard Coverage: With 13 SAE and 13 metric sizes, this set provides a comprehensive range that covers almost any standard hex fastener encountered in automotive or industrial environments.
Specifications:
- Material: Chrome Vanadium (CR-V) Steel
- Size Range (SAE): 0.05″, 1/16″, 5/64″, 3/32″, 7/64″, 1/8″, 9/64″, 5/32″, 3/16″, 7/32″, 1/4″, 5/16″, 3/8″
- Size Range (Metric): 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 7mm, 8mm, 9mm, 10mm
- Included in the Box:
- 13 SAE Hex Keys
- 13 Metric Hex Keys
How to Use:
- Identify the Fastener: Determine if the bolt is SAE or metric and select the corresponding color-coded section of the caddy.
- Select the Size: Choose the hex key that fits snugly into the fastener. There should be no “play” or wobbling when the key is inserted.
- Insert the Key: Using the chamfered end, slide the key into the fastener head until it is fully seated at the bottom of the hex socket.
- Apply Torque: Use the long arm of the key as a handle for maximum leverage to loosen a tight bolt. For rapid spinning, you can insert the long arm into the bolt and use the short arm as the handle.
- Store Correctly: After the task is complete, wipe the key clean and return it to its indexed slot in the caddy to maintain organization.
Benefits of Using Sunex Tools 26-Piece SAE/Metric Long Arm Hex Key Set (98526L):
- Correct Size Availability: Ensures that you have the correct tool for nearly any hex fastener, whether it follows American or International measurement standards.
- Reduced Hand Strain: The long-arm design significantly reduces hand strain by providing a longer moment arm for torque, making it easier to manage stubborn bolts.
- Protected Hardware: Chamfered tips ensure the tool is perfectly seated before force is applied, protecting your expensive hardware from damage.
- Efficient Organization: The color-coded caddy allows for instant distinction between metric and SAE tools, saving time on the job.
Features:
- L-Key Profile: Provides two working lengths for every size, allowing for either high torque or high-speed applications.
- Black Oxide Finish: A protective coating that helps prevent rust and corrosion during long-term storage in humid environments.
- Indexed Caddy: The storage holder features embossed size markings for every key, ensuring you always know which tool is missing.
- Tight Tolerances: The keys are manufactured to strict dimensional standards to ensure a precise fit within fastener sockets.
- Compact Storage: The folding design of the caddy allows the 26-piece set to fit easily into shallow tool chest drawers or portable bags.
