bar clamps
Bar clamps are essential tools in woodworking and construction, designed to hold workpieces firmly together during gluing, assembly, or machining operations. These versatile tools consist of a long steel bar with a fixed jaw at one end and a sliding jaw that can be adjusted along the bar's length. The sliding mechanism allows for quick positioning and secure clamping of materials of various sizes. Modern bar clamps feature ergonomic handles for comfortable operation, non-marring pads to protect work surfaces, and heavy-duty construction for durability. They come in various lengths ranging from 12 inches to 8 feet, accommodating different project requirements. The clamping mechanism typically incorporates a quick-release feature that enables rapid jaw adjustments and a threaded screw for applying precise pressure. Advanced models may include features like converting to spreaders, built-in measuring scales, and parallel jaw alignment systems for more accurate clamping results.
