Tidy up your wiring projects with this massive assortment of 170 black nylon snap bushings (also called cable grommets or hole plugs)! These little guys are used to line holes in metal, plastic, or wood panels to protect wires, cables, hoses, or pipes from sharp edges and provide insulation. The kit includes six different sizes to handle a wide range of jobs: 60 pcs of 5/16\ (8mm), 40 pcs of 3/8\ (10mm), 30 pcs of 1/2\ (11mm), 20 pcs of 5/8\ (16mm), 12 pcs of 3/4\ (19mm), and 8 pcs of 1\ (25mm). They're made from durable PA66 nylon, which is wear-resistant, corrosion-resistant, and long-lasting. Installation is a snap (literally) – just push them firmly into a correctly sized hole, and they lock securely in place. Perfect for organizing cables in computer cases, entertainment centers, automotive applications, electrical panels, DIY furniture, or any project where you need to pass something through a panel cleanly and safely. Everything comes neatly organized in a clear compartment storage box. An incredibly handy kit for any maker, technician, or DIY enthusiast's toolbox!
