S-MD 12-14 HWH #5 SS304 Self-drilling Metal Screws

Self-drilling screw for fast assembly in one step

Perfect Sealing (PS) feature – specially engineered geometry below the head which prevents over-compression of the EPDM washer, helping to more reliably seal out water

Fast and robust drill tip for use on high-strength steel (up to grade S 450 GD) with Racing Tip technology – a wave-form cutting edge which removes chips much faster and helps prevent point burn-out

For more reliable fastenings with defined load values

Fastening sheet metal and profiles to steel substructures and framing, with or without intermediate insulation layers

Stainless steel (A2) for fastening in mildly corrosive environments

Thick metal-to-metal connections (up to 0.59 inch)
