Choose the drill-hole size, bolt length and pack quantity required for your fixing.Understanding the size selectorThe M6–M14 selector labels refer to the required drill-hole diameter, rather than the outside thread diameter. For example, JCP part JAB06/08075 uses a 6mm drill hole, has an 8mm thread diameter and is 75mm long. Check the exact anchor against the supplier sheet before drilling.Available options Drill-hole size groups: M6, M8, M10, M12 and M14.

Installation and finishThese are self-tapping anchors installed into a pre-drilled, cleaned hole. Use the exact part's specified hole depth, embedment, fixture thickness and tightening torque.
