Hangon Q-Bolts are made by integrating a threaded plug made from silicone and steel. They are designed for use on work pieces that need to be hung and on similar applications. This makes them perfect for use with eyebolts (sold separately). Q-Bolts are available in sizes from M3 up to M24, Pipe Threads G1/8 to G1, and fine pitch metric threads M8x0.75 and M10x1.0. Q-Bolts are great for tight masking and protection at hole entrances, making them suitable for e-coating.
