Whether you’re mounting optics, assembling machinery, or tuning small fixtures, the Bondhus 10904 Ball-End L-Wrench delivers reliable performance and long service life.
Precision 5/64" Ball-End Hex L-Wrench
The 10904 is specifically sized for common 5/64" imperial hex fasteners:
Tip size: 5/64 inch hex, one of the most widely used small imperial sizes in mounts, clamps, electronics, and precision assemblies.
Ball-end tip: Engineered to enter the screw at up to a 25° angle, making it much easier to work when you can’t get perfectly straight on the fastener.
Imperial measurement system for a true, accurate fit on inch-based socket head cap screws and set screws.
The precisely machined ball tip helps reduce rounding and cam-out, protecting both the wrench and the fastener.
Long-Arm “L” Design – Reach & Leverage in a Compact Tool
The Bondhus 10904 is a long-arm L-wrench, giving you extra reach and torque without excess bulk:
Long arm length: 3.2 inches overall, providing improved leverage and the ability to reach recessed or obstructed screws.
Classic L-handle geometry lets you use the long arm as a lever for maximum torque, or the short arm for quick spinning and fast removal/installation.
Slim profile easily fits into tight assemblies, housings, rails, and other crowded spaces.
This makes the 10904 perfect for bench work, field kits, and tight-space fastener access.
Ball End – Work Easily at Up to 25° Angles
Bondhus pioneered the ball-end hex design, and the 10904 leverages that innovation:
Ball end inserts into the screw at up to a 25° angle, allowing you to work around obstacles and awkward angles that straight-cut hex keys can’t handle.
The ball profile “funnels” the tool into the screw head, speeding up engagement and making repetitive assembly work more efficient.
Designed for superior ball-end strength and working angle, reducing the risk of tip breakage and strip-out compared to cheap copies.
If your work regularly involves hard-to-reach screws, this ball-end design is a major productivity upgrade.
Protanium® High Torque Steel – Stronger, Tougher, Longer-Lasting
The Bondhus 10904 is made from the company’s proprietary Protanium® High Torque Steel:
Protanium steel is engineered to be up to 20% stronger than many competing tool steels, giving you more torque before bending or breaking.
Delivers more torque and twice the wear resistance of many standard steel hex keys, according to Bondhus.
Maintains tight tolerances at the tip for a secure fit even after repeated use.
This high-strength alloy makes the 10904 ideal for professional environments and high-cycle applications.
ProGuard™ Finish – Superior Corrosion Protection
To complement the Protanium steel core, Bondhus applies a ProGuard™ black finish:
ProGuard finish provides superior corrosion resistance, tested to be significantly more effective at preventing rust than many competing finishes.
Low-glare black color looks professional and is easy on the eyes under bright shop or range lighting.
Helps ensure the wrench stays in spec and serviceable over long-term use in oily, humid, or solvent-rich environments.
For shop and field users alike, this means more reliable, rust-resistant tools that keep performing year after year.
Compact & Shop-Friendly – Ideal for Multi-Station Use
Despite its rugged construction, the BALL-HEX “L” WRENCH 10904 is compact and easy to stock:
Overall long-arm length: 3.2" makes it easy to carry in a pocket, pouch, or range bag.
Commonly sold in 10-pack bulk configurations, so shops and maintenance teams can place a dedicated wrench at each workstation.
Lightweight yet strong, so it adds minimal weight to mobile tool rolls and field kits.
This combination of size, weight, and durability makes it a natural choice for professional tool setups.
