Company involved in a development project requires a metal quick fit solution for a reversible Harrow-point connected to a tine as showed in the pictures. The connection is currently with two bolts. The harrow point is very exposed in use, and especially the bolt and nuts are exposed to stress and tear. The current problem is deformation of thread and nut during use. The company is looking for a fastening mechanism to replace the bolt and nut solution. It must be fast to tighten / untighten and strong enough to withstand forces from a tractor The requirement will be around 2-300.000 units a year
