Hexagon Self Drill Screws c/w Washer – for Steel 4.0 – 22.0mm
- Spiral drill point suitable for steel thicknesses 4.0 – 22.0mm
- 8mm Hexagon head with 16mm bonded washer
- Three stage organic coating
These screws have a ‘twist drill’ style point for fast drilling into steel up to 22.0mm, a high tech organic coating giving superior rust proofing qualities to standard zinc plating and a neoprene bonded washer for weathersealing and isolating.
HSP50W is ideal for fixing brick ties to extra heavy steelwork. A Neoprene Isolating Washer should also be used between the stainless steel tie and the steelwork to separate the dissimilar metals.
For screws into these steel thicknesses a Tek Screwdriver giving 1500 – 2500rpm should be used to ensure adequate drilling speed and driving torque
