Description
The Bondhus 10-Piece Metric & SAE Hex End L-Wrench w/ProGuard (20393) is an essential collection of specialty tools engineered for precision work with very small fasteners. This set is a twin pack, containing two separate 5-piece L-wrench sets—one with common metric sizes and the other with a range of SAE (inch) sizes. It is the ideal solution for professionals, hobbyists, and anyone who needs to work on miniature applications, such as electronics, precision instruments, and model making. Each L-wrench is crafted from Bondhus’ proprietary ProTanium High Torque Steel, a material designed for exceptional strength and wear resistance. The tools are finished with a ProGuard dry surface, which not only provides five times the corrosion resistance of other finishes but also offers a better, more secure grip. With precision-machined tips and chamfered ends, these wrenches are designed to fit perfectly into screw heads, preventing stripping and allowing for maximum torque transfer.
KEY FEATURES AND BENEFITS:
- Comprehensive Twin Pack: The set includes two separate 5-piece sets, giving you a total of 10 L-wrenches in both metric and SAE sizes, ensuring you have the right tool for a wide variety of small fasteners.
- ProTanium High Torque Steel: Made from a proprietary steel blend, these wrenches are up to 20% stronger than standard steel, offering superior strength and double the wear resistance for a longer tool life.
- ProGuard Finish: This specialized surface finish is environmentally friendly and provides five times more corrosion resistance than competitor finishes, protecting your tools from rust and providing a non-slip grip.
- Precision-Machined Tips: Each wrench tip is machined for an exact fit, reducing the risk of stripping or rounding out screw heads, which is critical when working with delicate and small components.
- Made in the USA: Bondhus tools are manufactured in the United States and are backed by a lifetime warranty, highlighting the commitment to quality and craftsmanship.

HOW TO USE:
- Identify the Correct Size: Determine the size of the hex screw you need to work with. If it’s a very small fastener, carefully try both the metric and SAE wrenches to find the one that fits snugly.
- Insert the Wrench: Choose the correct L-wrench from the set. Insert the short end of the wrench into the hex socket of the screw.
- Apply Torque: Grip the long end of the wrench. To loosen a screw, turn the wrench counter-clockwise. To tighten, turn it clockwise. Use controlled, steady pressure to avoid slipping.
- Repeat as Needed: For screws in hard-to-reach places, you can also use the long end of the wrench for reach, with the short end for turning. The short end is typically used for higher torque applications.
