The fastest and easiest way of joining work /counter tops in a matter of seconds! The ZIPBOLT UT (10.500) connector is a new practical and innovative solution that saves time and money in assembling work / counter tops and panels. The Zipbolt UT requires a simple 5mm Allen key or hex bit as a driving tool and this ensures a very positive engagement. The NEW all metal Zipbolts which now have diecast gear housing are more durable and are able to achieve even higher torque levels than previously.
