The Joyner Bolt is a quality UK made timber fixing, created to improve the time, speed and quality of grip when joining decking materials together. They are revolutionary new timber fixings, with an engineered 45mm x 45mm x 3mm square spiked head, designed to improve the experience and short falls of the coach bolt. The engineered spiked head helps to reduce the damage caused to the timber by tightening a standard coach bolt and a nut locking facility. The Joyner Bolt is suitable for use when joining timber to timber or timber to metal. M12 bolts available in a range of sizes.
