John Puhr, industry veteran with Triangle Fastener Corp. for over 35 years, is pleased to announce a new addition to their BLAZER Drill Screw line.
“Quick…what is the largest diameter self-drilling screw readily available from stock? If you said a ¼”, you would be correct until recently.”
Triangle Fastener Corp. (TFC) recently introduced the 5/16” diameter BLAZER 3 self-drilling screw in six lengths ranging from 1” to 8”. They will drill and tap metal thicknesses up to .210” and have a 3/8” HWH that allows you to use existing tools and equipment for installation. All parts are TRISEAL coated and offer 1,000 hours salt spray protection from corrosion when tested according to ASTM B117. They are available with or without a galvanized bonded EPDM sealing washer.
Puhr adds, “Consider the 5/16 diameter BLAZER 3 drill screw when your next project calls for increased shear or diaphragm requirements. It offers an additional 460 lbs. of shear strength over a ¼” diameter self-drilling screw. It also is a great “filler screw” when replacing ¼” diameter screw in a maintenance or retrofit situation.”
