Lindapter is the world's leading innovator in steelwork clamping systems. Their unique clamping systems eliminate the requirement to drill or weld steel. When compared to traditional steel clamping / connection methods, Lindapter provides faster installation, significantly reduced costs and preserves the integrity of the steelwork. Lindapter clamping systems are suitable for a variety of steel work ranging from steel beams to steel hollow sections. The 'Countersunk Head' version of the Hollo-Bolt is a suitable cavity fixing for hollow sections or conventional steelwork where access is available from one side only. It also ensures that the fixing protrusion from the steelwork is kept to a minimum whilst still using a plain drilled hole in the supporting section and the outer plate / bracket.
