Description
Overview:
The Timco Hex Self-Drilling Screw is a steel fastener designed for fixing metal to metal in construction and industrial settings. At 5.5 x 38 mm, it combines a robust diameter with a practical length for reliable steel-to-steel connections. The self-drilling point cuts its own hole, removing the need for pilot drilling and speeding up installation. Suited to heavy section work, it is ideal for fastening into steel up to 12 mm thick when installed correctly. The hexagon head allows positive drive with a standard hex nut driver on a cordless drill or impact driver. Supplied in a pack of 100 for site use and maintenance teams, this model (MPN: H38B) is commonly used on roofing and cladding jobs where consistent, high-strength fixing is required.
