The threads are as specified with 12.5mm long M4 thread on one end and 12.5mm No.8 woodscrew on the other. I cut down the M4 portion to 5mm long for my application. I needed a generous amount of Loctite on the M4 thread because the fit is so very loose in the M4 rubber isolators I was fitting. ## Features - Thread Diameter: M4(Machine screw); 4mm / 0.16"(Wood screw); Total Length: 25mm / 1" - Wood Screw Thread Length: 12.5mm / 0.49"; Machine Screw Thread Length: 12.5mm / 0.49" - Material: Carbon steel construction with zinc plated, high hardness, provides great corrosion resistance and antirust ability for long service life. - Advantage: The hanger bolt is good for wooden furniture jointing.
