Hex L-shaped Wrench
We take an H5 size (5 mm across flats) S2 material L wrench as an example. The hardness is HRC 58-62. The minimum break torque is ≥25 N·m. This follows ISO 2936. In real use, you can safely put out 15-20 N·m of torque. This force is enough to tighten an M6×1.0, grade 12.9 internal hex bolt (recommended torque is about 12 N·m).
Turn Bolts Anywhere with Our Hex L-shaped Wrench
Do you need a tool that fits in your pocket? An internal hex wrench is the most portable tool. Our Hex L-shaped Wrench has an L shape. The long arm gives you high torque. You can tighten or remove rusty screws. The short arm lets you spin fast. It is good for the first few turns. We are a Shanghai factory. We have made fasteners for 20 years.
Check Our Torque Data and Hardness Levels
We take an H5 size (5 mm across flats) S2 material L wrench as an example. The hardness is HRC 58-62. The minimum break torque is ≥25 N·m. This follows ISO 2936. In real use, you can safely put out 15-20 N·m of torque. This force is enough to tighten an M6×1.0, grade 12.9 internal hex bolt (recommended torque is about 12 N·m). The size range is H2 (2 mm across flats) to H8 (8 mm across flats). This fits M3 to M10 internal hex bolts. The hex across flats tolerance is ±0.03 mm. This gives a tight fit with the bolt hex slot. It will not slip. The long arm length is about 100-150 mm based on the size. The short arm length is about 20-40 mm. We offer 45# steel and S2 alloy steel. 45# steel is an economic choice. Hardness is HRC 48-52. It works for normal loads. S2 alloy steel is a pro choice. Hardness is HRC 58-62. It has higher strength and better wear resistance.

Why Our Surface Finish and Ball End Option Help You
The production uses cold forming. The hex edges have a chamfer. This stops scratching on the bolt hole. Surface finish is nickel plating or black oxide. Nickel plating thickness is 5-10 μm. The surface is bright silver white. Neutral salt spray test lasts 48 hours with no rust. The nickel layer has a hardness of about HV 400-500. It wears better than zinc plating. For sizes H3 to H8, we can add a ball end. This lets you work at a 25-degree angle. It is good for tight spaces. But the torque ability of the ball end is about 60-70% of the straight end. Use it for the first turns only. Use the straight end for final tightening. We have our own R&D team. You can share your special needs. Free samples are ready for stock items. We support OEM and ODM orders. Cold headed parts start at 50,000 pieces. Mass production takes 2-3 weeks for standard parts. Custom products take 4 weeks. We can add color sleeves for size identification, folding sets, or ball end sets.
The entire product line is fully customizable.
