This exclusive pack contains knobs and bolts arranged together to help secure and enhance your woodworking jig and fixture assemblies. They are designed to offer a supplemental and long term clamping strategy to your projects, and work seamlessly with any drill press, lathe or saw that accommodates a 5/16”-18 internal thread size (also most ¾ inch wide by 3/8 inch deep t-tracks). Whether you’re a professional or DIY enthusiast, these knobs are easy to use, remove and don’t require any tools. Exceptional Build Each knob is made with Polypropylene, a heat resistant thermoplastic known for its toughness and durability. However, its most noticeable feature is the robust, ergonomic design that’s smooth to touch and comfortable to handle – eliminating hand injuries caused by inferior quality and tiny, hard to turn nuts. In addition, we’ve chosen to use molded plated steel inserts. In doing so, we’ve taken away the threat of stripping, while offering a helping hand in fighting corrosion or rust. These items may be simplistic in function, but our engineers have made sure that you’ll actually feel the quality and craftsmanship that has gone into each knob. Highly Versatile Design With a spark of creativity, these knobs and bolts can work amazingly with an assortment of applications, including: • Fences • Featherboards • Motorized Anchor Systems • Routing Jigs • Flip Top Cabinets The possibilities are endless, making them a must-have for any shop.
