Durable Fastening – Thanks to 10.9 carbon steel
10.9 carbon steel is specified for high hardness and tensile strength, reducing the risk of bending or snapping under load. Corrosion-resistant and scratch-resistant finishes increase longevity in normal workshop environments.
Long-lasting joints and fewer replacements over time, suitable for repeated assembly and disassembly. Strong core material supports demanding mechanical and hobby tasks.
Cleaner, Low-Profile Assemblies – With Countersunk Hex Socket Head Screws
Countersunk flat heads sit flush with surfaces and widen the tension range while lowering average load during tightening, aiding even clamp distribution. Hex socket heads enable tightening with a matching wrench for accurate torque.
Flush finishes reduce snagging and look neater on furniture and panels. Easier torque control helps avoid over-tightening and damage to softer materials.
Secure Clamping and Faster Work – With Hex Nuts, Flat Washers and Wrench
Hex nuts allow precise tightening and carry larger loads, while flat washers increase bearing area to protect bolt heads and distribute clamping force. A single wrench is included to match hex socket heads for quick assembly.
Improved clamping reliability and extended fastener life. Faster installation and more consistent results for routine repairs and build projects.
